Cyclone Center Talk
Either no storm or post-tropical would be applicable here. I'd go for post-tropical but the impact on the final analysis should be similar
Yes, Zovacor, this is quite frequent. Its an embedded storm and probably either the weakest or second weakest example is closest match
Quite the eye storm
later in the sequence of images we see the small eye storm become shear or curved band and now the target storm appears dominant
Nice example of two systems in same image - target storm (centre) is a curved band but there is a small eye storm in top right of image
Hi Shir-El. Indeed, many images are not close to examples. This is a shear storm type and I would judge to be closest to the third case.
Hi Edoan1, the white part is very cold and high clouds - very active convection.
More on Danny and its impacts at https://en.wikipedia.org/wiki/Hurricane_Danny_(1997) if interested.
I would agree on post-tropical. It has probably just transitioned after it had hit the gulf coast as a well presented cat 1 storm
I'd go weak embedded but the flat SE edge to cold clouds suggests substantial shear too so a real toss-up
Yes, the coldest cloud tops are white here so cold as to go off the scale. Very tall clouds to get that cold.
This one is being ripped apart by shear. Centre hard to tell but shear is NE-> SW. Either shear or no-storm in my view
Yes, dkolesch this is a remnant storm. There is evidence of low level circulation but no convection. Very weak shear or post-trop!
Maybe the very low clouds (grey) giving the mottled appearance? Otherwise looks fine to me. May have been a caching issue / partial download
I think either eye or strong curved-band would be reasonable here. It is pretty much 50:50. I would probably lean ever so slightly curved.
I'd classify as strong embedded center and place center estimate in the dark blue area enclosed by darkest blue/white semi-circle
Irene here is a reasonably strong embedded centre. It is relatively symmetric with some outflow
I would also have gone for a weak curved-band here. Unclear exactly where the centre is and little organisation.
I'd agree this is a no storm image. There are just a set of thunder clouds here with no obvious circulation
Someone forgot to put a coin in the satellite's electricity meter 😃. Clearly this should be classified as 'Other -> Edge effect'
This 1 a real humdinger. I leant #false-eye and classified as very strong #curved-band (centre S of 'eye'). What would you have chosen? Why?
Possible, but at this stage I'd go for an embedded storm as I would not be sure that wasn't a false-eye
This could be either curved band or perhaps embedded. Its a false-eye. I'd go curved-band on balance as curve dominant but not clear cut.
I'd say this is a very weak curved-band. Lots of spots of convection but very little structure
I think that best tracks data may be quite a long way out here ... curved band with centre almost off image right
My feeling, looking at the way the banding is spiralling in is that the centre is the 1st light blue blob just above largest dark blue band
I'd agree this is a false eye and would classify as a relatively strong curved band
I'd say the light blue dot above the dark blue banding may be an eye forming. Otherwise its a very strong embedded storm
Yes, a classic eye structure in the middle there. Probably middling-intensity due to lack of pronounced banding
Photo-bombed shear storm. Eye see you big brother.
I'd agree. Definite eye in this one.
Strong curved or embedded I would say.
I'm guessing that the eye storm is photo-bombing a #no-storm image here
May well be an eye with thin high cloud trying to be cleared out
This page might help WailingWolf: https://en.wikipedia.org/wiki/Fujiwhara_effect (and links therein obviously)
I'd say its too unstructured to be an eye-storm. Its probably a raggedy #curved-band here but its almost curved back on itself ...
very nice eye storm here. Almost buzzsaw like.
The flat clouds on N edge does suggest a degree of shear. Could also be embedded. Either would be a reasonable estimate here
I'd have gone for curved here but I see the argument for eye
Don't you just hate it when your younger better looking sibling photo bombs your selfie? 😃
Very nice #pinhole-eye indeed. Wouldn't want to be anywhere near this on a ship.
Yep, fairly weird alright. I'd go with a weak #curved-band on this one
It could also be curved-band or embedded though. I don't think its eye - this is a #false-eye in the largest cloud structure in my opinion
Its a strange storm alright. Tough one. I would probably lean to shear (North to South) with centre just at tip of the small circ. blob.
I'd probably tend #embedded but I can see an arguement for going #eye too.
This is either embedded or curved-band. You are right not an eye storm. I'd lean curved-band with centre at apex of 'hook' but embedded poss
If curved centre is between the band and the central cloud blob, its second weakest type and short curve. Either would be a good est. here.
If embedded then the centre is in darkest blue blob in centre and its weakest embedded with least tail
Hi, Steampunkgal, this one is marginal. It could be embedded (central blob) or curved (long band). I would be hard pressed to pick.
Thought about going for #eye (central hole in the warm clouds) but ended up going #curved-band. What would you have chosen for this one?
Somewhere in this storm was my 22,500th image. I'm going to claim it was this pretty one.
Agreed, this is very early storm and may be #no-storm or weak #curved-band. Centre as far as it exists would be somewhere left of centre.
Its a curved-band storm by my eye at least.
Hi DorosZoo, its certainly got multiple convective centres. I'd say the centre is somewhere near RHS of the centred blob of cold clouds
A rule of thumb is if >1 color warmer cloud its an eye. In this case is 4 colors warmer in eye so a strong eye candidate here.
I would say this is an eye. There is likely some thin high cloud giving the orange.
I'd concur with your skepticism here and personally classify as a #curved-band
I'd say this could be shear, eye or post-tropical. I'd be torn between a very weak eye and post-tropical. Prob. the latter?
I spy with my little eye ...
Indeed, impressive convective burst there.
#eye or #false-eye? I think #false-eye but hmmm it really could be an eye.
Hi, shwetha.lv, indeed the white clouds are the coldest. These are very high clouds.
Nice #curved-band example from Lola (Charlie, I will not eat a tomato ... :->)
Yes, this one a little tricky. I'd say it has a #false-eye + that the true centre is the dark blue blob in the middle of image. #embedded ?
In this case I would classify the storm as weak embedded with centre in the dark blue cloud mass somewhere near the island (white outline)
Hi Felmy, this may indeed be two circulations. About 5% or so of images incl. 2 storms. Where they do you should classify more central one.
This storm had more lives than a cat. At least 3 eyewall stages interspersed I thought?
Interesting decay phase. Curved or very weak eye? Was an eye prior
Tiny eye I assume?
I'd say #False-eye here. This looks like a curved-band storm trying to get organized to me.
That is some seriously cold cloud tops around the eye.
On its own would have been tempted to go eye. But if click on image takes to entire storm and on p.7 you see this is transition to embedded
Delicate #curved-band
I can't believe that this is an eye. Beforehand its curved and yet is there a more plausible classification than a very weak eye? #stumped
Will alert the zooniverse folks to this issue.
Hi Keaneo, I'd say no storm is a good guess here. There really isn't enough structure to justify anything beyond no-storm.
Eye? Its a really odd storm that looks extratropical most of time then this image pops out
I'd go for curved, too, probably the 4th or 5th strongest.
pinhole #eye
May be either embedded or strong shear - shear is from E to W (flattened Eastward flank of cold clouds)
Weak curved band slightly left of center or possibly even no-storm?
Raggedy-eye marks 500K up - awesome that its from Orson too (sorry, very bad pun there - I'll get my coat)
Whole series of these edge effects for this storm. Fixable?
Given its lack of structure I would also have said not eye at this stage but eye possibly emerging
Eye or not? I went embedded in the end but eye trying to form I think.
Jeepers
With this image I join the legends of the project bretarn and baha23 in the 20K club. Shear joy writ large?
I went eye false-eye eye false-eye and eventually there were no more daisy petals at false-eye. What would you have chosen?
Hi Shonenbatman, there is no real right or wrong. Your estimates help. Here I would put the curvature as dominant so go weak curved-band.
Another storm position issue with this storm. Kinda funky. Coming out of left field quite literally.
Is this a real eye or a false-eye? One of the harder images. Also storm not where best tracks thinks it should be?
comma
Very marginal between embedded and eye. I would likely have gone embedded too.
eye-spy?
warm eye.
Also, interestingly he made it almost to the Pacific coast before returning and regaining strength passing over FL. Was a monster.
Was this your 500th? 😃
Sunday brain-teaser: eye? curved? A badly made ommlette?
According to best tracks this storm had no windspeed at this point ... hmmmm.
storm top left is playing eye-spy here ...
eye-storm? Or ring donut?
Woah. You would not want to be anywhere near this in a boat.
I'd have gone for weakest eye given the coherency of the two bands and general structure. Its a late season warm storm.
I'd say curved band, the second weakest form but with a very cold curve
false-eye? I started this image 3 times and eventually decided strongest curved-band. What would others have classified as?
Could be an eye. However the two large spirals suggest winds into a center around the bogger blue blob so I'd prob. tend to embedded here.
the estimate will be good. And one real strength is when we get 10 estimates and they diverge it tells us s/thing useful viz. Uncertainty
I'd say this is a weak embedded (1st or 2nd strength). Central feature is the blob with white in middle. But so long as went weak (1/2)
Storm off to the East is not the target but much bigger. I think the BAMS paper said 5% of images incl. 2 storms. Always go w/more central.
Hi hlgoldsborough, this is a case where there are two storms. The target storm is over Bahamas and weak-shear / no-storm. (1/2)
Is Danny giving us a little eye here or not?
Hmmm I wonder could this be an eye storm? 😃
I'd go weak end curved or embedded. Probably embedded with center under northern blob on its right hand side of the coldest clouds
I'd say curved. Where the center is though ... well ...
A raggedy-doll eye
Nabi was an insane storm. Eye lasted forever. This is start but grew into a giga-eye later on. Take a look at the entire storm. Fascinating.
Could also argue tightly wound curved-band. I went eye with the lower left center 'hole' as eye FWIW. Later storm undoubtedly has eye.
eye or not?
I'd go #eye. My rule of thumb is if the center is 2 or more tones lighter than the surrounding bands then its likely an eye. Here is 3.
Do the BoM (I assume they are the relevant regional center) tend to come in lower than NHC for storm intensity?
Its an eye storm but which one is the real eye? I went for the one further south but flip a coin time?
Hi Tapper13, always try to mark the strongest feature near the image center. In this case its either curved or embedded (I'd choose this)
Is it playing I-spy with my little eye? Something beginning with WA? Western Australia
I'd have gone weakest shear here - marking the center as the weak eye like feature and then nearest red being almost directly west of this.
I'd classify as weakest shear except that there is no red point in view.
Is it just me or is Hernan all wound up here?
Its a quotation mark. Was there one spinning in the other hemisphere the other way to close the quote? I'd go embedded second weakest.
It may be going through an eye-wall-replacement cycle. Science team thoughts?
Carlos has two big gaps with no images in its lifetime. Assume we could recover these?
No doubt on this classification. Would not have wanted to be in a boat anywhere near this one ...
#no-eye - I'd go weak #embedded
Now that is more like an image to celebrate 15K classifications ...
I classified 15,000 images and all I got was #no-storm. Where is the big eye-storm to greet such a milestone huh? #no-fair
I thought it might be. Pretty cool that we can see some #erc in the images. Subject for future blogpost cch001 / knappster?
Cold-top clouds ... brrrrr. Chilly
Saturday quiz ... is the eye the small middle feature in the orange or the larger area bounded by yellow clouds? How would you classify?
We apologize for the poor picture quality. Please do not adjust your television set. Normal service shall be resumed shortly.
Giving me the warm-eye
Mind the curve
Deep blue eye
I'm not trying to be sexy. It's just my way of expressing myself when I move around. #elvis-quotes-for-Elvis(1998)
And it was my 14,500th image apparently to boot. Wasn't a tough one TBH.
Prothon, both you and the process are correct here. L hand image is 24 hours prior & gives us info on whether intensifying. R hand is target
Small but perfectly formed. Alvin (not to be confused with a chipmunk clearly ...)
The relatively flattened edge is windward (leading edge) and the long tail is leeward (the cloud stream). So W->E here
Not sure what I would call it but I would go 2nd curved-band w/ centre just to left and up a tad from the coldest blob (furthest right one)
Embedded is a good guess. Could equally be shear (all clouds streaming West to East). Center is either under or just to West of the top blob
Nobody is ever miles out. I could be way wrong 😃. Classify as you see it. We get each image several times by distinct people.
us to clean up and better understand the data in a globally consistent manner. Let us know if this helps at all?
The graph beneath and map shows the best tracks data - wind speed and pressure and track. This data is inhomogeneous and you are helping
Rebex, I would classify this one as strong shear with the center some distance to the East of the cold clouds.
This is cold!
best track data said this was 25-35 knots. I think the islanders would beg to disagree!
Unsurprisingly I went curved band. I think paradoxically it was the 13,000th image. Yes I really should get out more I agree.
more eye than storm here. Can we do a storm-eye rather than eye-storm classification?
Now, I'm pretty sure I've seen this one before somewhere ... 😃
The Saturday quiz image: How would you classify this? FWIW I went embedded although none really fit.
It does look like two storms interacting. Stronger one is bottom left but target storm will be nearest center which I wld go weak embedded
Its the zooniverse motif no?
Hawaii uh-oh
Home sweet home 😃
It's Turbo (spot the guy with young boys ...)
I broke your colorscale. Sorry 'bout that, yours Bolaven
Someone please chuck another quid in the electricity meter ...
Not the most inspiring note to hit a dozen thou with but they all count. Keep up cch001 😃
I shall wrought terrible vengence upon thee with my caveman club of doom. Yours, Frank.
ying with your yang?
Looks like an Indian land cyclone as has been discussed in various parts before.
@DZM see e.g. http://talk.cyclonecenter.org/#/boards/BCC0000005/discussions/DCC0000052?page=1&comment_id=531790a821c81f0d94001403
Centre is just under the grey cloud. I'd classify as the second option under shear, marginally arguably the third.
It's a nailed on #shear-storm. You can see the circulation in the low white clouds with the cold high clouds displaced NE of centre.
brrrrrrr
Poor little Emily getting looked over by her big brother like that ...
My four year old gives his permission altho requests a cut of the royalties being half American 😃
My 4 year old classified this perfectly. If a 4 year old can do it you can too 😃
I would probably classify as #curved-band although it could indeed be an #eye - it is very interesting.
Is that an #edge or simply a #ledge?
Very small indeed
It's Australian land mass so may be correct. Very warm temperatures would be black.
wide-eyed and bushy tailed?
How did a storm with a clearly defined #eye in 1995 not get named?!?
Ryan spun up quick to this. 200 to go to 10,000 classifications. Do I get free upgrades and lounge entry when I get there?
#shear That or someone took two images cut them in half and photoshopped them back together again 😃
I suspect this is a #false-eye right? I went #shear storm. What would others have chosen?
#dizzy
Is Sam giving me the #cold-eye here?
Something strangely beguiling about classifying storms like this while the snow falls outside the window in the winter darkness ...
Its wound very tight and has tails out from different sectors suggesting strong outflow which of course begets strong inflow.
See http://en.wikipedia.org/wiki/List_of_named_tropical_cyclones in our period maggie once, bart thrice, lisa 5 times and two Marge's.
Possibly a whole bunch of other Simpsons characters, obviously.
There have been marge, maggie, bart and lisa but never Homer. Maybe we could have a simpsons themed campaign and #simpsons-storms on twitter
Ay caramba! - well it is typhoon Bart. History doesn't relate whether it ate anyone's shorts ...
Quite the tail to this one.
I'd put the center as the light blue dot in the middle of the dark blue / white in RHS blob. Almost an emerging eye perhaps w/high cirrus?
There is so much space between the two sets of cold cloudtops it could be more complicated than a simple replacement cycle.
This is a really odd image which is why I flagged it. Replacement cycles are fairly common but not clear that this is one or not.
Could hang this one on my wall ... 😃
Number 8000 up and its a doozy ... do keep up cch001 😃
Wikipedia to the rescue? http://en.wikipedia.org/wiki/Hurricane_Cesar–Douglas
So Cesar started in the Atlantic but here has crossed and is a curved band in the E Pacific. Correct?
The storm cch001 and I have been discussing gets more strange a few hours later. This one is cool but I would not know how to classify it!
abstract art 😃
Okay, so what would y'all classify this one as?!?
More #eye than #storm ... a whole set of these for this one. Its not the size of the ship its the motion of the ocean? 😃
It is indeed some impressively cold (high) cloud tops
Quite the curve.
Did someone say mind the #curve ?
Well its got a lot of spin evident from the warm low clouds that is for sure.
Very nice eye storm indeed
A real #eye ?
could easily be mistaken here for #two-eyes. Real #eye is the one more dead center of the image if you were wondering ...
Peekaboo #eye see you ... these two storms are close. No wonder the target storm is sheared.
I will never not ever eat a tomato? 😃
I also went strongest #embedded-center but it was very marginal. The eye looked like it was about to pop out any moment.
#eye? #not-eye? #eye? #not-eye? Did I get out of the left hand side of the bed or the right hand side this morning?
To my eye I would have said that the light blue dot in the center was an #emerging-eye feature. Depending what side of the bed I woke up on.
I had forgotten what a beast this had been. #monster
This one was very tough. What do you think? I went for an #embedded-center but it is so disorganized still it just seems to sit funny?
I would say either a weak embedded center or some shear. Definitely a storm
Not the tropical island getaway you were looking for? 😃
Yes, its really interesting how marginal this is. Its why automated techniques have issues and where you, the citizen scientists, can help!
Not sure. I do know that science team member Knappster did a back of envelope that in about 1-2% of images 2 or more storms will be visible.
Would be incredibly interesting to take these images that are the examples and just see how many times people correctly identified ...?
I agree. But even if you classified as some storm type you'd classify so weak it would not register as a tropical system of any strength.
and there is no 'right' answer in many cases as you'll see from much of the discussion here. Your clicks really do count.
is one of the real scientific strengths of getting multiple assessments of each image. Something we could never hope to get without you ...
Susan, yes some of them are. This one looks like #shear with the true storm centre to SW of main clouds. That some are not easy [cont ...]
This is a monster of an #eye-storm. Really cold clouds out every which way a long way.
This one is another very marginal decision. Emerging eye but still very cold. I went #embedded but either would be possible I guess
Thanks to Knappster of science team by the way for doing the calcs on proximal storms 😃
to both be in image. Most of time one or both are likely to be weak, but this may be an occasion when #2-storms complicates interpretation
Might be two systems #target-storm in centre and tail from second (larger?) storm in top right. About 1% of time #2-storms close enough
Something like if there is at least a two colour band dip in the centre then its an #eye but only 1 would be #strong-embedded?
We've had a couple of these marginals here lately. I wonder whether there is a rule of thumb about when it goes #strong-embedded to #eye?
Looking at the whole storm it looks like a case of storm indigestion. It burps that long tail out then swallows it back up a day or so later
This storm is #bad-geolocation in IbTRACS. Keeps saying centre is by African coast so imagery left shifted. Gets worse with time.
I would suspect #shear from the straight left hand edge to cold tops. Where the center is though is tough. Possibly just under the cold tops
This one was very tough. I went strong #curved-band but as either side was so much stronger and had #eye not quite sure ...?
#eye storm (barely) being #sheared apart.
I hadn't seen quite such a breakdown near a still intact #eye yet. It doesn't look highly sheared so any thoughts as to cause?
I can see a reasonable case could be made for all three possibilities though.
Personally I would go #embedded-center because the warm cloud 'hole' is not central in the cold cloud tops and no shear is apparent.
I would personally classify as #curved-band with centre just to North of the easternmost island. Regardless it is #weak so #no-storm fine
I assume this is early in the life? Quite frequently this disorganized. May be #curved-band with center on LHS of northern blob. May be ...!
I'd say it is either #post-tropical or #highly-sheared. Could make the case centre near image centre with convection sheared strongly SE.
Is this a #raggedy-eye? I started thinking off dry intrusion but it hung around so long that I changed to eye. Fascinating storm.
Did I miss something? This just gave me a twenty image classification marathon for this storm ... w/o a break. Time for bed after that ...!
Lets hope we don't see anything like this this season huh?
2000th image a busted flush. Yes, I've been away but I'm finally free of assessments activities for a while. Did I miss much? :-s
This one didn't look like an eye until magnified, when it did, so I had to start over 😦. Pertinent to current blog post?
And 'wrong' is a nuanced word here because its hard to say for such a complex storm what the 'right' answer is.
The power of cyclonecenter is we get lots of classifications of each storm so don't worry about getting the odd one 'wrong'.
But the best is towards the end. This is real abstract art here ... 😃
Or this ...
This one for example ...
This is surely not an #eye ? Mind you looking through the storm it ahs some very very weird eyes at various times.
Before anyone says it - I know I should get out more ...
There I was doing the early images thinking #1500 was going to be a wash - some non-storm gumph. I got this. Almost as if you guys knew?😃
Will whoever forget to turn the centrifuge off please step up and admit it? 😃
And its watching ... YOU! For our British contingent of a certain age is this where Gordon the Gopher went after Philip Schofield moved on?
Tilt screen 90 degrees anti-clockwise (easier with tablet / laptop) ... this storm is alive ...
Monster #curved-band ? It was an #embedded-center prior - haven't seen too many storms make that transition so #not-very-confident
and no obvious land-sea interaction in the storm history.
But, caveat emptor there is no 'right' answer in such cases. Interesting case study storm. Wonder why it had such trouble. No obvious shear
So, it could be classified either as #eye or #embedded-center here. I would probably tend to #eye defining the northern one as the true #eye
Looking at the storm history page it looks like this storm repeatedly tries to attain a well-defined #eye. This is one of those times.
It certainly looks like it could be a very small pinhole #eye . I would have gone for #eye personally also
Pretty spectacular
I spy with my very very incredibly little eye ...
seperated by a really weak #eye-storm that almost dissipates.
This storm is really interesting - it has two periods when it is an #eye-storm and the second period includes two distinct strong eye storms
If you click on the 'view storm page' link under the image above then you can view thumbnails of the entire storm.
Beautiful #eye-storm
Looking at the whole storm history this is one seriously wierd storm. It has more lives than a cat.
#raggedy-eye
What happened to the left hand side of this storm? Surely too far from land to be land interaction?
I was torn between monster #curved-band and #embedded-center with monster banding. Could be either, I think.
Its a beautiful image. Yes, should be the medium / normal blue in this case. If you were in a ship you would not want to be near this one...
This #eye looks like its shedding a tear ...
And I may be totally wrong ...!
Eastern has a broader area of cold tops even though its smaller total cloud area. So its where most of the deep convection is in progress.
convective area being the dominant one and place the center under the white cloud top there.
to interactions between two #embedded-centre storms. Its marginal which is more significant. I'd go #embedded-centre with the Eastern
Hi VictoriaC, this one is rather tricky. I would be guided by the two significant convective areas. The two eye-like holes are likely due
Why am I left thinking krispy kreme donuts here? This is spectacular.
When two storms go to war? This one had me stumped. I went for #curved-band but it could just be something really strange (TM pending)
Is this for real? This looks like a badly cooked ommlette with garish food coloring.
Two storms this close together off Australia seems unusual. They kind of destroy each other then the North one regenerates.
How is it possible to be maintaining that structure with so much land interference and over such cool waters?
dunkin donuts. That aint no eye. Q is how on earth did this configuration come to pass?
Toughie - #embedded-center or #curved-band? This storm has a whole run of these where its a little bit of this little bit of that ...
Don't have to be #eye-storms to be #pretty. Structures in this are fascinating
Really perfectly round inner-storm on this one. Storm is fascinating when you look through the full storm page.
Why did this have me thinking aye-aye captain? Or should that be eye-eye captain?
If this is the 35Kts stated in best track plot then I'm changing my name by deed poll to Rumpelstiltskin ...
Do you get a prize for weird eyes? This thing had a neat little eye then this ...
Could also be a case where the best track estimate is questionable / uncertain. One of the reasons for projec is to identify such situations
Did a five year old get their crayon out? I plumped for curved band but to be honest its just a crayon mess isn't it?
I spy with my little #eye something beginning with hurricane. This is a beautiful compact little storm. Eerily round ...
Earlier in its life there are three strung out what look like #embedded-center beads SW to NE. Its by far the strangest storm I have done.
this storm has a #huge-eye. But eye never cold top surrounded in the set I saw. Well worth a closer look. Wierd storm
Luther?
This one spent its entire life North of the Aleutian islands. I know the tropics have been expanding but ...!!! geolocation errors?
This one just suddenly had a beautiful eye out of nowhere. Before that it was just an embedded center meandering about. You never know ...
Another #eye-storm - you need to get yourself a German ISP Chris ... 😃
I seem to be getting more when classifying in Germany than I did in the US (I'm at NDACC steering committee). Perhaps try a German ISP mask?
Neat little #eye-storm
Maybe I'm too dumb, but this is the first storm that has progressed back thru its lifetime not forwards in the set of six. Caught me out.
If it was under #shear or #land-interaction a reforming of the circulation is more likely
Eye or no eye? There had been dry intrusion which may have got dragged into the center. Tough call.
It could be worse. It could be like Nadine is (was?). That would be some truly funky moves on the Atlantic dance floor ...
The whole set for this storm are too zoomed ... can't see enough of the structure surrounding the storm.
Someone forgot to put money in the electricity meter for the satellite ...
This thing looks like its getting ripped apart like a slice of French Bread. #bit-of-everything ?
#raggedy-eyes I assume because there is some dry air intrusion wrapping in from the West?
It looks like it might be #limb imagery which can distort the view.
Certainly possible but near the main island of Japan which means could be #shear or #land-interaction. Possible low-level circ center to E?
Its possible but if it is the convection is very lop-sided. It could equally be #curved-band. Eyes are relatively speaking 'rare'.
This one had me flummoxed to say the least. The whole set was #limb imagery but this one was impossible to give an answer to.
Its not clear from the close-up whether it is over land or over ocean, but regardless it is near land and so possibly #land-interaction ?
Is there #storm-2-storm-interaction
Either no storm or post-tropical would be applicable here. I'd go for post-tropical but the impact on the final analysis should be similar
Yes, Zovacor, this is quite frequent. Its an embedded storm and probably either the weakest or second weakest example is closest match
Quite the eye storm
later in the sequence of images we see the small eye storm become shear or curved band and now the target storm appears dominant
Nice example of two systems in same image - target storm (centre) is a curved band but there is a small eye storm in top right of image
Hi Shir-El. Indeed, many images are not close to examples. This is a shear storm type and I would judge to be closest to the third case.
Hi Edoan1, the white part is very cold and high clouds - very active convection.
More on Danny and its impacts at https://en.wikipedia.org/wiki/Hurricane_Danny_(1997) if interested.
I would agree on post-tropical. It has probably just transitioned after it had hit the gulf coast as a well presented cat 1 storm
I'd go weak embedded but the flat SE edge to cold clouds suggests substantial shear too so a real toss-up
Yes, the coldest cloud tops are white here so cold as to go off the scale. Very tall clouds to get that cold.
This one is being ripped apart by shear. Centre hard to tell but shear is NE-> SW. Either shear or no-storm in my view
Yes, dkolesch this is a remnant storm. There is evidence of low level circulation but no convection. Very weak shear or post-trop!
Maybe the very low clouds (grey) giving the mottled appearance? Otherwise looks fine to me. May have been a caching issue / partial download
I think either eye or strong curved-band would be reasonable here. It is pretty much 50:50. I would probably lean ever so slightly curved.
I'd classify as strong embedded center and place center estimate in the dark blue area enclosed by darkest blue/white semi-circle
Irene here is a reasonably strong embedded centre. It is relatively symmetric with some outflow
I would also have gone for a weak curved-band here. Unclear exactly where the centre is and little organisation.
I'd agree this is a no storm image. There are just a set of thunder clouds here with no obvious circulation
Someone forgot to put a coin in the satellite's electricity meter 😃. Clearly this should be classified as 'Other -> Edge effect'
This 1 a real humdinger. I leant #false-eye and classified as very strong #curved-band (centre S of 'eye'). What would you have chosen? Why?
Possible, but at this stage I'd go for an embedded storm as I would not be sure that wasn't a false-eye
This could be either curved band or perhaps embedded. Its a false-eye. I'd go curved-band on balance as curve dominant but not clear cut.
I'd say this is a very weak curved-band. Lots of spots of convection but very little structure
I think that best tracks data may be quite a long way out here ... curved band with centre almost off image right
My feeling, looking at the way the banding is spiralling in is that the centre is the 1st light blue blob just above largest dark blue band
I'd agree this is a false eye and would classify as a relatively strong curved band
I'd say the light blue dot above the dark blue banding may be an eye forming. Otherwise its a very strong embedded storm
Yes, a classic eye structure in the middle there. Probably middling-intensity due to lack of pronounced banding
Photo-bombed shear storm. Eye see you big brother.
I'd agree. Definite eye in this one.
Strong curved or embedded I would say.
I'm guessing that the eye storm is photo-bombing a #no-storm image here
May well be an eye with thin high cloud trying to be cleared out
This page might help WailingWolf: https://en.wikipedia.org/wiki/Fujiwhara_effect (and links therein obviously)
I'd say its too unstructured to be an eye-storm. Its probably a raggedy #curved-band here but its almost curved back on itself ...
very nice eye storm here. Almost buzzsaw like.
The flat clouds on N edge does suggest a degree of shear. Could also be embedded. Either would be a reasonable estimate here
I'd have gone for curved here but I see the argument for eye
Don't you just hate it when your younger better looking sibling photo bombs your selfie? 😃
Very nice #pinhole-eye indeed. Wouldn't want to be anywhere near this on a ship.
Yep, fairly weird alright. I'd go with a weak #curved-band on this one
It could also be curved-band or embedded though. I don't think its eye - this is a #false-eye in the largest cloud structure in my opinion
Its a strange storm alright. Tough one. I would probably lean to shear (North to South) with centre just at tip of the small circ. blob.
I'd probably tend #embedded but I can see an arguement for going #eye too.
This is either embedded or curved-band. You are right not an eye storm. I'd lean curved-band with centre at apex of 'hook' but embedded poss
If curved centre is between the band and the central cloud blob, its second weakest type and short curve. Either would be a good est. here.
If embedded then the centre is in darkest blue blob in centre and its weakest embedded with least tail
Hi, Steampunkgal, this one is marginal. It could be embedded (central blob) or curved (long band). I would be hard pressed to pick.
Thought about going for #eye (central hole in the warm clouds) but ended up going #curved-band. What would you have chosen for this one?
Somewhere in this storm was my 22,500th image. I'm going to claim it was this pretty one.
Agreed, this is very early storm and may be #no-storm or weak #curved-band. Centre as far as it exists would be somewhere left of centre.
Its a curved-band storm by my eye at least.
Hi DorosZoo, its certainly got multiple convective centres. I'd say the centre is somewhere near RHS of the centred blob of cold clouds
A rule of thumb is if >1 color warmer cloud its an eye. In this case is 4 colors warmer in eye so a strong eye candidate here.
I would say this is an eye. There is likely some thin high cloud giving the orange.
I'd concur with your skepticism here and personally classify as a #curved-band
I'd say this could be shear, eye or post-tropical. I'd be torn between a very weak eye and post-tropical. Prob. the latter?
I spy with my little eye ...
Indeed, impressive convective burst there.
#eye or #false-eye? I think #false-eye but hmmm it really could be an eye.
Hi, shwetha.lv, indeed the white clouds are the coldest. These are very high clouds.
Nice #curved-band example from Lola (Charlie, I will not eat a tomato ... :->)
Yes, this one a little tricky. I'd say it has a #false-eye + that the true centre is the dark blue blob in the middle of image. #embedded ?
In this case I would classify the storm as weak embedded with centre in the dark blue cloud mass somewhere near the island (white outline)
Hi Felmy, this may indeed be two circulations. About 5% or so of images incl. 2 storms. Where they do you should classify more central one.
This storm had more lives than a cat. At least 3 eyewall stages interspersed I thought?
Interesting decay phase. Curved or very weak eye? Was an eye prior
Tiny eye I assume?
I'd say #False-eye here. This looks like a curved-band storm trying to get organized to me.
That is some seriously cold cloud tops around the eye.
On its own would have been tempted to go eye. But if click on image takes to entire storm and on p.7 you see this is transition to embedded
Delicate #curved-band
I can't believe that this is an eye. Beforehand its curved and yet is there a more plausible classification than a very weak eye? #stumped
Will alert the zooniverse folks to this issue.
Hi Keaneo, I'd say no storm is a good guess here. There really isn't enough structure to justify anything beyond no-storm.
Eye? Its a really odd storm that looks extratropical most of time then this image pops out
I'd go for curved, too, probably the 4th or 5th strongest.
pinhole #eye
May be either embedded or strong shear - shear is from E to W (flattened Eastward flank of cold clouds)
Weak curved band slightly left of center or possibly even no-storm?
Raggedy-eye marks 500K up - awesome that its from Orson too (sorry, very bad pun there - I'll get my coat)
Whole series of these edge effects for this storm. Fixable?
Given its lack of structure I would also have said not eye at this stage but eye possibly emerging
Eye or not? I went embedded in the end but eye trying to form I think.
Jeepers
With this image I join the legends of the project bretarn and baha23 in the 20K club. Shear joy writ large?
I went eye false-eye eye false-eye and eventually there were no more daisy petals at false-eye. What would you have chosen?
Hi Shonenbatman, there is no real right or wrong. Your estimates help. Here I would put the curvature as dominant so go weak curved-band.
Another storm position issue with this storm. Kinda funky. Coming out of left field quite literally.
Is this a real eye or a false-eye? One of the harder images. Also storm not where best tracks thinks it should be?
comma
Very marginal between embedded and eye. I would likely have gone embedded too.
eye-spy?
warm eye.
Also, interestingly he made it almost to the Pacific coast before returning and regaining strength passing over FL. Was a monster.
Was this your 500th? 😃
Sunday brain-teaser: eye? curved? A badly made ommlette?
According to best tracks this storm had no windspeed at this point ... hmmmm.
storm top left is playing eye-spy here ...
eye-storm? Or ring donut?
Woah. You would not want to be anywhere near this in a boat.
I'd have gone for weakest eye given the coherency of the two bands and general structure. Its a late season warm storm.
I'd say curved band, the second weakest form but with a very cold curve
false-eye? I started this image 3 times and eventually decided strongest curved-band. What would others have classified as?
Could be an eye. However the two large spirals suggest winds into a center around the bogger blue blob so I'd prob. tend to embedded here.
the estimate will be good. And one real strength is when we get 10 estimates and they diverge it tells us s/thing useful viz. Uncertainty
I'd say this is a weak embedded (1st or 2nd strength). Central feature is the blob with white in middle. But so long as went weak (1/2)
Storm off to the East is not the target but much bigger. I think the BAMS paper said 5% of images incl. 2 storms. Always go w/more central.
Hi hlgoldsborough, this is a case where there are two storms. The target storm is over Bahamas and weak-shear / no-storm. (1/2)
Is Danny giving us a little eye here or not?
Hmmm I wonder could this be an eye storm? 😃
I'd go weak end curved or embedded. Probably embedded with center under northern blob on its right hand side of the coldest clouds
I'd say curved. Where the center is though ... well ...
A raggedy-doll eye
Nabi was an insane storm. Eye lasted forever. This is start but grew into a giga-eye later on. Take a look at the entire storm. Fascinating.
Could also argue tightly wound curved-band. I went eye with the lower left center 'hole' as eye FWIW. Later storm undoubtedly has eye.
eye or not?
I'd go #eye. My rule of thumb is if the center is 2 or more tones lighter than the surrounding bands then its likely an eye. Here is 3.
Do the BoM (I assume they are the relevant regional center) tend to come in lower than NHC for storm intensity?
Its an eye storm but which one is the real eye? I went for the one further south but flip a coin time?
Hi Tapper13, always try to mark the strongest feature near the image center. In this case its either curved or embedded (I'd choose this)
Is it playing I-spy with my little eye?
Something beginning with WA?
Western Australia
I'd have gone weakest shear here - marking the center as the weak eye like feature and then nearest red being almost directly west of this.
I'd classify as weakest shear except that there is no red point in view.
Is it just me or is Hernan all wound up here?
Its a quotation mark. Was there one spinning in the other hemisphere the other way to close the quote? I'd go embedded second weakest.
It may be going through an eye-wall-replacement cycle. Science team thoughts?
Carlos has two big gaps with no images in its lifetime. Assume we could recover these?
No doubt on this classification. Would not have wanted to be in a boat anywhere near this one ...
#no-eye - I'd go weak #embedded
Now that is more like an image to celebrate 15K classifications ...
I classified 15,000 images and all I got was #no-storm. Where is the big eye-storm to greet such a milestone huh? #no-fair
I thought it might be. Pretty cool that we can see some #erc in the images. Subject for future blogpost cch001 / knappster?
Cold-top clouds ... brrrrr. Chilly
Saturday quiz ... is the eye the small middle feature in the orange or the larger area bounded by yellow clouds? How would you classify?
We apologize for the poor picture quality. Please do not adjust your television set. Normal service shall be resumed shortly.
Giving me the warm-eye
Mind the curve
Deep blue eye
I'm not trying to be sexy. It's just my way of expressing myself when I move around. #elvis-quotes-for-Elvis(1998)
And it was my 14,500th image apparently to boot. Wasn't a tough one TBH.
Prothon, both you and the process are correct here. L hand image is 24 hours prior & gives us info on whether intensifying. R hand is target
Small but perfectly formed. Alvin (not to be confused with a chipmunk clearly ...)
The relatively flattened edge is windward (leading edge) and the long tail is leeward (the cloud stream). So W->E here
Not sure what I would call it but I would go 2nd curved-band w/ centre just to left and up a tad from the coldest blob (furthest right one)
Embedded is a good guess. Could equally be shear (all clouds streaming West to East). Center is either under or just to West of the top blob
Nobody is ever miles out. I could be way wrong 😃. Classify as you see it. We get each image several times by distinct people.
us to clean up and better understand the data in a globally consistent manner. Let us know if this helps at all?
The graph beneath and map shows the best tracks data - wind speed and pressure and track. This data is inhomogeneous and you are helping
Rebex, I would classify this one as strong shear with the center some distance to the East of the cold clouds.
This is cold!
best track data said this was 25-35 knots. I think the islanders would beg to disagree!
Unsurprisingly I went curved band. I think paradoxically it was the 13,000th image. Yes I really should get out more I agree.
more eye than storm here. Can we do a storm-eye rather than eye-storm classification?
Now, I'm pretty sure I've seen this one before somewhere ... 😃
The Saturday quiz image: How would you classify this? FWIW I went embedded although none really fit.
It does look like two storms interacting. Stronger one is bottom left but target storm will be nearest center which I wld go weak embedded
Its the zooniverse motif no?
Hawaii uh-oh
Home sweet home 😃
It's Turbo (spot the guy with young boys ...)
I broke your colorscale. Sorry 'bout that, yours Bolaven
Someone please chuck another quid in the electricity meter ...
Not the most inspiring note to hit a dozen thou with but they all count. Keep up cch001 😃
I shall wrought terrible vengence upon thee with my caveman club of doom. Yours, Frank.
ying with your yang?
Looks like an Indian land cyclone as has been discussed in various parts before.
@DZM see e.g. http://talk.cyclonecenter.org/#/boards/BCC0000005/discussions/DCC0000052?page=1&comment_id=531790a821c81f0d94001403
Centre is just under the grey cloud. I'd classify as the second option under shear, marginally arguably the third.
It's a nailed on #shear-storm. You can see the circulation in the low white clouds with the cold high clouds displaced NE of centre.
brrrrrrr
Poor little Emily getting looked over by her big brother like that ...
My four year old gives his permission altho requests a cut of the royalties being half American 😃
My 4 year old classified this perfectly. If a 4 year old can do it you can too 😃
I would probably classify as #curved-band although it could indeed be an #eye - it is very interesting.
Is that an #edge or simply a #ledge?
Very small indeed
It's Australian land mass so may be correct. Very warm temperatures would be black.
wide-eyed and bushy tailed?
How did a storm with a clearly defined #eye in 1995 not get named?!?
Ryan spun up quick to this. 200 to go to 10,000 classifications. Do I get free upgrades and lounge entry when I get there?
#shear That or someone took two images cut them in half and photoshopped them back together again 😃
I suspect this is a #false-eye right? I went #shear storm. What would others have chosen?
#dizzy
Is Sam giving me the #cold-eye here?
Something strangely beguiling about classifying storms like this while the snow falls outside the window in the winter darkness ...
Its wound very tight and has tails out from different sectors suggesting strong outflow which of course begets strong inflow.
See http://en.wikipedia.org/wiki/List_of_named_tropical_cyclones in our period maggie once, bart thrice, lisa 5 times and two Marge's.
Possibly a whole bunch of other Simpsons characters, obviously.
There have been marge, maggie, bart and lisa but never Homer. Maybe we could have a simpsons themed campaign and #simpsons-storms on twitter
Ay caramba! - well it is typhoon Bart. History doesn't relate whether it ate anyone's shorts ...
Quite the tail to this one.
I'd put the center as the light blue dot in the middle of the dark blue / white in RHS blob. Almost an emerging eye perhaps w/high cirrus?
There is so much space between the two sets of cold cloudtops it could be more complicated than a simple replacement cycle.
This is a really odd image which is why I flagged it. Replacement cycles are fairly common but not clear that this is one or not.
Could hang this one on my wall ... 😃
brrrrrrr
Number 8000 up and its a doozy ... do keep up cch001 😃
Wikipedia to the rescue? http://en.wikipedia.org/wiki/Hurricane_Cesar–Douglas
So Cesar started in the Atlantic but here has crossed and is a curved band in the E Pacific. Correct?
The storm cch001 and I have been discussing gets more strange a few hours later. This one is cool but I would not know how to classify it!
abstract art 😃
Okay, so what would y'all classify this one as?!?
More #eye than #storm ... a whole set of these for this one. Its not the size of the ship its the motion of the ocean? 😃
It is indeed some impressively cold (high) cloud tops
Quite the curve.
Did someone say mind the #curve ?
Well its got a lot of spin evident from the warm low clouds that is for sure.
Very nice eye storm indeed
A real #eye ?
could easily be mistaken here for #two-eyes. Real #eye is the one more dead center of the image if you were wondering ...
Peekaboo #eye see you ... these two storms are close. No wonder the target storm is sheared.
I will never not ever eat a tomato? 😃
I also went strongest #embedded-center but it was very marginal. The eye looked like it was about to pop out any moment.
#eye? #not-eye? #eye? #not-eye? Did I get out of the left hand side of the bed or the right hand side this morning?
To my eye I would have said that the light blue dot in the center was an #emerging-eye feature. Depending what side of the bed I woke up on.
I had forgotten what a beast this had been. #monster
This one was very tough. What do you think? I went for an #embedded-center but it is so disorganized still it just seems to sit funny?
I would say either a weak embedded center or some shear. Definitely a storm
Not the tropical island getaway you were looking for? 😃
Yes, its really interesting how marginal this is. Its why automated techniques have issues and where you, the citizen scientists, can help!
Not sure. I do know that science team member Knappster did a back of envelope that in about 1-2% of images 2 or more storms will be visible.
Would be incredibly interesting to take these images that are the examples and just see how many times people correctly identified ...?
I agree. But even if you classified as some storm type you'd classify so weak it would not register as a tropical system of any strength.
and there is no 'right' answer in many cases as you'll see from much of the discussion here. Your clicks really do count.
is one of the real scientific strengths of getting multiple assessments of each image. Something we could never hope to get without you ...
Susan, yes some of them are. This one looks like #shear with the true storm centre to SW of main clouds. That some are not easy [cont ...]
This is a monster of an #eye-storm. Really cold clouds out every which way a long way.
This one is another very marginal decision. Emerging eye but still very cold. I went #embedded but either would be possible I guess
Thanks to Knappster of science team by the way for doing the calcs on proximal storms 😃
to both be in image. Most of time one or both are likely to be weak, but this may be an occasion when #2-storms complicates interpretation
Might be two systems #target-storm in centre and tail from second (larger?) storm in top right. About 1% of time #2-storms close enough
Something like if there is at least a two colour band dip in the centre then its an #eye but only 1 would be #strong-embedded?
We've had a couple of these marginals here lately. I wonder whether there is a rule of thumb about when it goes #strong-embedded to #eye?
Looking at the whole storm it looks like a case of storm indigestion. It burps that long tail out then swallows it back up a day or so later
This storm is #bad-geolocation in IbTRACS. Keeps saying centre is by African coast so imagery left shifted. Gets worse with time.
I would suspect #shear from the straight left hand edge to cold tops. Where the center is though is tough. Possibly just under the cold tops
This one was very tough. I went strong #curved-band but as either side was so much stronger and had #eye not quite sure ...?
#eye storm (barely) being #sheared apart.
I hadn't seen quite such a breakdown near a still intact #eye yet. It doesn't look highly sheared so any thoughts as to cause?
I can see a reasonable case could be made for all three possibilities though.
Personally I would go #embedded-center because the warm cloud 'hole' is not central in the cold cloud tops and no shear is apparent.
I would personally classify as #curved-band with centre just to North of the easternmost island. Regardless it is #weak so #no-storm fine
I assume this is early in the life? Quite frequently this disorganized. May be #curved-band with center on LHS of northern blob. May be ...!
I'd say it is either #post-tropical or #highly-sheared. Could make the case centre near image centre with convection sheared strongly SE.
Is this a #raggedy-eye? I started thinking off dry intrusion but it hung around so long that I changed to eye. Fascinating storm.
Did I miss something? This just gave me a twenty image classification marathon for this storm ... w/o a break. Time for bed after that ...!
Lets hope we don't see anything like this this season huh?
2000th image a busted flush. Yes, I've been away but I'm finally free of assessments activities for a while. Did I miss much? :-s
This one didn't look like an eye until magnified, when it did, so I had to start over 😦. Pertinent to current blog post?
And 'wrong' is a nuanced word here because its hard to say for such a complex storm what the 'right' answer is.
The power of cyclonecenter is we get lots of classifications of each storm so don't worry about getting the odd one 'wrong'.
But the best is towards the end. This is real abstract art here ... 😃
Or this ...
This one for example ...
This is surely not an #eye ? Mind you looking through the storm it ahs some very very weird eyes at various times.
Before anyone says it - I know I should get out more ...
There I was doing the early images thinking #1500 was going to be a wash - some non-storm gumph. I got this. Almost as if you guys knew?😃
Will whoever forget to turn the centrifuge off please step up and admit it? 😃
And its watching ... YOU! For our British contingent of a certain age is this where Gordon the Gopher went after Philip Schofield moved on?
Tilt screen 90 degrees anti-clockwise (easier with tablet / laptop) ... this storm is alive ...
Monster #curved-band ? It was an #embedded-center prior - haven't seen too many storms make that transition so #not-very-confident
and no obvious land-sea interaction in the storm history.
But, caveat emptor there is no 'right' answer in such cases. Interesting case study storm. Wonder why it had such trouble. No obvious shear
So, it could be classified either as #eye or #embedded-center here. I would probably tend to #eye defining the northern one as the true #eye
Looking at the storm history page it looks like this storm repeatedly tries to attain a well-defined #eye. This is one of those times.
It certainly looks like it could be a very small pinhole #eye . I would have gone for #eye personally also
Pretty spectacular
I spy with my very very incredibly little eye ...
seperated by a really weak #eye-storm that almost dissipates.
This storm is really interesting - it has two periods when it is an #eye-storm and the second period includes two distinct strong eye storms
If you click on the 'view storm page' link under the image above then you can view thumbnails of the entire storm.
Beautiful #eye-storm
Looking at the whole storm history this is one seriously wierd storm. It has more lives than a cat.
#raggedy-eye
What happened to the left hand side of this storm? Surely too far from land to be land interaction?
I was torn between monster #curved-band and #embedded-center with monster banding. Could be either, I think.
Its a beautiful image. Yes, should be the medium / normal blue in this case. If you were in a ship you would not want to be near this one...
This #eye looks like its shedding a tear ...
And I may be totally wrong ...!
Eastern has a broader area of cold tops even though its smaller total cloud area. So its where most of the deep convection is in progress.
convective area being the dominant one and place the center under the white cloud top there.
to interactions between two #embedded-centre storms. Its marginal which is more significant. I'd go #embedded-centre with the Eastern
Hi VictoriaC, this one is rather tricky. I would be guided by the two significant convective areas. The two eye-like holes are likely due
Why am I left thinking krispy kreme donuts here? This is spectacular.
When two storms go to war? This one had me stumped. I went for #curved-band but it could just be something really strange (TM pending)
Is this for real? This looks like a badly cooked ommlette with garish food coloring.
Two storms this close together off Australia seems unusual. They kind of destroy each other then the North one regenerates.
How is it possible to be maintaining that structure with so much land interference and over such cool waters?
dunkin donuts. That aint no eye. Q is how on earth did this configuration come to pass?
Toughie - #embedded-center or #curved-band? This storm has a whole run of these where its a little bit of this little bit of that ...
Don't have to be #eye-storms to be #pretty. Structures in this are fascinating
Really perfectly round inner-storm on this one. Storm is fascinating when you look through the full storm page.
Why did this have me thinking aye-aye captain? Or should that be eye-eye captain?
If this is the 35Kts stated in best track plot then I'm changing my name by deed poll to Rumpelstiltskin ...
Do you get a prize for weird eyes? This thing had a neat little eye then this ...
Could also be a case where the best track estimate is questionable / uncertain. One of the reasons for projec is to identify such situations
Did a five year old get their crayon out? I plumped for curved band but to be honest its just a crayon mess isn't it?
I spy with my little #eye something beginning with hurricane. This is a beautiful compact little storm. Eerily round ...
Earlier in its life there are three strung out what look like #embedded-center beads SW to NE. Its by far the strangest storm I have done.
this storm has a #huge-eye. But eye never cold top surrounded in the set I saw. Well worth a closer look. Wierd storm
Luther?
This one spent its entire life North of the Aleutian islands. I know the tropics have been expanding but ...!!! geolocation errors?
This one just suddenly had a beautiful eye out of nowhere. Before that it was just an embedded center meandering about. You never know ...
Another #eye-storm - you need to get yourself a German ISP Chris ... 😃
I seem to be getting more when classifying in Germany than I did in the US (I'm at NDACC steering committee). Perhaps try a German ISP mask?
Neat little #eye-storm
Maybe I'm too dumb, but this is the first storm that has progressed back thru its lifetime not forwards in the set of six. Caught me out.
If it was under #shear or #land-interaction a reforming of the circulation is more likely
Eye or no eye? There had been dry intrusion which may have got dragged into the center. Tough call.
It could be worse. It could be like Nadine is (was?). That would be some truly funky moves on the Atlantic dance floor ...
The whole set for this storm are too zoomed ... can't see enough of the structure surrounding the storm.
Someone forgot to put money in the electricity meter for the satellite ...
This thing looks like its getting ripped apart like a slice of French Bread. #bit-of-everything ?
#raggedy-eyes I assume because there is some dry air intrusion wrapping in from the West?
It looks like it might be #limb imagery which can distort the view.
Certainly possible but near the main island of Japan which means could be #shear or #land-interaction. Possible low-level circ center to E?
Its possible but if it is the convection is very lop-sided. It could equally be #curved-band. Eyes are relatively speaking 'rare'.
This one had me flummoxed to say the least. The whole set was #limb imagery but this one was impossible to give an answer to.
Its not clear from the close-up whether it is over land or over ocean, but regardless it is near land and so possibly #land-interaction ?
Is there #storm-2-storm-interaction
