ATL: COLIN - Recon Discussion

[artist]

Here we can discuss RECON findings.

Seems they have found ssw winds as well as I believe it was 40 kt winds as well.

[artist]

ok, here is what I was mentioning above on the kts found -

163330 1925N 06039W 9771 00321 0136 +227 +188 121034 034 036 000 00

[x-y-no]

It's a sharper wave than I expected them to find.

It'll be interesting to see what wind direction they find on the SW side.

[artist]

ok, this really surprsies me, look at these winds -

Sorry, but does anyone have the key to decode these HDOBs? I have forgotten how.

the last column is whether they feel there is an error with the obs or not - 00 means none
the 4 columns before that - the one next to the error column is the winds seen from the sfmr at the surface- on board radar I believe, the 3 before that the last 2 numbers are the knots found at flight level.


ooops, that should be 2 columns away from the error column is the sfmr (on board radar) - not the one next to it, then the 2 to the left of it are actually flight level readings.

That's a nice big patch of TS winds ... Way off east of the axis of course ...

Heavily sheared but I'm somewhat surprised how strong it still is.

[artist]

hope that helps.
and here is the NHC's recon page, scroll down for pdf's that will explain -

you can also go to http://www.tropicalatlantic.com/recon/ which has a decoder set up for you -

you beat me to it!

Based on that data, it is probably a 45 kt wave/low.

For land about to get hit, a 45 kt tropical storm and a 45 kt low would do the same impacts.

Will be very interesting to see what recon gets when they fly next time...

seems there is a flight on the way. Left from Kessler I believe.

[cycloneye]

artist, the first mission today departed from St Croix?

yeah, that's why I am confused, unless they had trouble with the plane. They didn't finish sending any obs today past the 17th obs. so maybe a new plane on the way?

[thetruesms]

I was going to say, leaving now seems a bit early for a 6Z fix from St. Croix

[KWT]

So is that the next mission, 06z from St.Croix. They normally don't do it for invests (which effectivly it is) but obviously since it maybe developing they may well go into the system.

[cycloneye]

What you are posting at the recon thread may be or a training mission or as you said sending another plane to ST Croix. By the way,it not says this header=0104A INVEST instead is WXWXA

[clfenwi]

Given that the plane is meandering around 98° W, it appears that AF304 is a training mission. Seems likely to me that the next mission is the one scheduled to launch at 1630Z, tomorrow.

[artist]

according to this is there not a scheduled 2230 today which is what time this one left?
