TD 27 Recon Discussion

[cycloneye]

Let's post the comments about what the crew finds here and leave the sticky recon thread for the data to be posted.

[P.K.]

Plane currently descending then. Every time I try to post in the recon thread you beat me to it by a couple of seconds. (I deleted the last one)

LOL Yes plane very soon will enter the system.

[SouthFloridawx]

can someone decode the dropsounde? Also Luis at what height are they measuring the winds so I know what to reduce the flight level winds to.

80 or 90?

[P.K.]

The plane is 300m up looking at the mini obs.

[cycloneye]

I confess that I dont know how to decode the dropsondes.

A Vortex Message comming shortly.

[SouthFloridawx]

The plane is 300m up looking at the mini obs.

does that mean reduce to 70% of it's value...

[P.K.]

lol, I find it easier looking at the raw data.

1733. 1429N 06805W 00306 5029 198 015 226 226 016 00281 0000000000
Time...Lat....Long.....Pressure Height..Absolute D-Value...Wind Dir.. 30 second wind speed....Air Temp...Dew Point...Max 10 second wind....Radar Alt.....0 means data is not suspect

I'm not sure of the wind conversion they use from 300m though.

Edit - Ah dropsondes, slightly different there. The one you posted had a pressure reading of 1019hPa by the looks of it

That is correct.

Remember, whenever they are flying weak systems (near 1500ft.) you generally use 70%. It is 80% for 850mb and 90% for 700mb.

is that 300 Meters?

I would think the reduction would be less than 90% then

ok thanks for clearing that up... it confuses me...

[P.K.]

Looks like it to me. Usually they fly at 500m in these systems though.

[cjrciadt]

Vortex where are thou?

Second plane just taken off?

[cycloneye]

Aparently that are making two passes before the vortex message.Right now they crossed once again the center looking for west winds.If they dont find those this could be downgraded but if the vortex comes it means that they found a closed circulation.

P.K. that is a training mission as the identification says not says Cyclone.

I was starting to wonder if there was a center anymore....

What do you think Luis?

I don't think there is... looks like a bunch of sheared mess.

[cycloneye]

They are taking their time to have a vortex message and that says to me they are have a hard time to close a circulation.Let's see what happens in the next few minutes.

What are the co-ordinates of the center?
