2011 Tropical Waves

[RL3AO]

I know PK does this on a UK forum. Why not have one on the great storm2k?

Note: For identification time, I'll use the first time its mentioned in the Tropical Weather Discussion, not when it shows up on the surface analysis. Also, click to enlarge the satellite images.

Instead of using satellite imagery, I suggest TPW imagery as available here:

http://cimss.ssec.wisc.edu/tropic/real- ... /main.html

Most recent still images are here:
http://cimss.ssec.wisc.edu/tropic/real- ... s/?C=M;O=D

TPW images will show the wave a lot better than satellite. In fact, some waves may not be detectable by satellite at times.

Here's today's image. You can clearly see the wave axis along 48W. And you can see what looks like another wave about to emerge off the coast of Africa:

Good idea. Thanks for the archive link too.

Updated for wave #2.

Wave #2 removed after twelve hours. Maybe jumped the gun a bit?

I wonder if there is a list of first tropical waves and how much forming going to whenever satellites were around.

Not the area you were expecting was it?

Wave # 5 introduced at 18z

TROPICAL WAVE IS ALONG 59W S OF 12N MOVING W NEAR 15 KT. THIS IS
A LOW AMPLITUDE TROPICAL WAVE THAT WAVE FORMERLY CARRIED AS A
SURFACE TROUGH. IT HAS BEEN TRACKED BACK TO WEST AFRICA...AND IS
NOW APPROACHING TRINIDAD AND VENEZUELA. ISOLATED MODERATE
CONVECTION IS FROM 4N-12N BETWEEN 56W-62W.

Looking at TPW image, wave 6 looks to be coming soon near 30W.

I'm not seeing much continuity looking at waves 3, 4 and 5. Are you getting these wave locations from the NHC's outlook? That's an issue I've had with their outlooks over the years. The wave location/identification is highly dependent on who's doing the analysis. They're jumping all over the place from day to day. The same wave may have been identified twice so far.

Tropical Wave #7

Holder post until TWD comes out.

Oh yeah, at the Senegal coast!

Are you sure? Wave 3 was dropped yesterday at 18z at 73W then Wave 5 was added at 0z at 59W.

Just keep an eye on the continuity from day to day. Waves don't generally just dissipate (like #3 along 73W). They're just harder to identify at times.

Heres what the TWD said for wave 3


TROPICAL WAVE THAT IS INLAND OVER COLOMBIA ALONG 72W/73W S OF
13N HAS MOVED INTO AN AREA OF LOWER PRESSURE AND HAS BEEN
DROPPED FROM THE SURFACE ANALYSIS.
