ATL : TROPICAL DEPRESSION ALEX - RECON DISCUSSION

[cycloneye]

Pressure a tad lower at the final pass of this mission,989.8 mbs.

[KWT]

Yeah there is so little difference its probably just Alex showing some fluctuation in terms of pressure.

990mbs probably is about right.

[cycloneye]

The next mission departs around 4:30 PM EDT or 3:30 PM CDT.

FLIGHT TWO - TEAL 70
A. 29/0000, 0600Z
B. AFXXX 0701A ALEX
C. 28/2030Z
D. 21.1N 93.4W
E. 28/2300Z TO 29/0600Z
F. SFC TO 10,000 FT

[KWT]

Yep, will be very interesting to see what recon find next time in, I'd expect some slight strengthening to occur as the storm gets into slowly lower shear.

[cycloneye]

The Gulfstream jet that samples the upper atmosphere is at this time flying over 40,000 feet.

29/0000Z
B. NOAA9 0601A ALEX
C. 28/1730Z..........CORRECTED
D. NA
E. NA
F. 41,000 TO 45,000 FT

[brunota2003]

Yep...Google Earth shows it has dropped 3 sondes thus far

[Aquawind]

Gulfstream data should be in the 00Z model runs then! YAY!! With the weak steering currents and nearly stationary movement this could be interesting tonight.

[cycloneye]

I dont know a lot about the dropsondes data but I see the area of 200mb with light winds. However, I would like to see from any of our pro mets to come and explain all those numbers and graphics the dropsonde of the Gulfstream jet has.

[cycloneye]

There are two planes in the air right now,the GulfStream jet and the AF304.

[KWT]

I have a sneaky feeling recon will find a stronger system when it gets there, convection is going up over the center for the first time in a while with any real meaning.

[cycloneye]

Plane will decend shortly to operational altitud.

[KWT]

Then we can see whether the convective bursting that has been occuring recently has helped to strengthen Alex.

[cycloneye]

In a few minutes we will know how strong Alex is as plane is on operational altitud.

[brunota2003]

The nontasked mission from NOAA (P3 research type) just took off.

[cycloneye]

I think the reduction in this mission is not 75% right?

[KWT]

Expecting to see winds that once again justify 50kts, so whilst it may or may not offically be stronger, the winds will overall be higher, I also expect a slightly lower pressure again.

[CrazyC83]

Flying at 850mb = reduction of 80%.

Need 60 kt FL winds to support current intensity on that basis, need 80 kt to support Hurricane Alex.

[cycloneye]

Lets see how the winds correspond to that.By the way,the plane apparently will not make a pass before the 7 PM CDT advisory as is flying NW.

[brunota2003]

They must of seen something they were interested in...or the NHC wanted to check out...they are in the area of colder cloud tops, so

[clfenwi]

brunota said what I was about to comment, looks like they went off course a bit to check out the convection. Probably will bend back in for a center pass fix for the advisory.
