H Dolly Recon Discussion Thread

[cycloneye]

Lets see if NHC sends or not the plane down to 94L later this morning.Discussions about the data from the plane will be posted here.

If they go,it will depart around 11:45 AM EDT.

ATLANTIC REQUIREMENTS
1. SUSPECT AREA...(LESSER ANTILLES)
FLIGHT ONE...TEAL 70
A. 16/1800Z
B. AFXXX 01AAA INVEST
C. 16/1545Z
D. 13.5N 56.0W
E. 16/1700Z TO 16/2200Z
F. SFC TO 10,000 FT

[cycloneye]

They will fly into 94L.

[HURAKAN]

I have class later today but will keep in touch. Very interesting.

[cycloneye]

Thunder44,will you have a contest today? The question for the contest would be if recon finds or not a closed circulation.

[Gustywind]

Hope they won't find any circulation Cycloneye:eek:

Is this pretty typical to fly into an invest? Is it because it is so close to land?

They will fly into most invests that threaten land that could be near depression/storm stregth.

pojo,there is a discussion thread already.

is this the direction column?

no that is the winds.

winds 314* at 049kts

[pojo]

Here is the numbers and what they mean

061230 1658N 08215W 7000 03000 9000 +108 +108 352159 161 145 100 00
Taking the last line:

1) 06:12:30 GMT
2) 16.58N
3) 82.15W
4) Static pressure in airplane of 700.0hPa
5) Geopotential height of 3000m
6) 30 second surface pressure mean extrapolation of 900.0hPa
7) 30 second mean air temperature of +10.8C
8) 30 second mean dew point of +10.8C
9) 30 second mean wind direction of 352 degrees
10) 30 second mean wind of 159kts
11) Ten second gust of 161kts
12) Peak ten second SFMR surface wind of 145kts
13) SFMR precipitation rate of 100mmh[sup]-1[/sup]
14) Suspect data codes are as follows:

First column indicates status of positional variables as follows:
0 All parameters of nominal accuracy
1 Lat/lon questionable
2 Geopotential altitude or static pressure questionable
3 Both lat/lon and GA/PS questionable

Second column indicates status of meteorological variables as follows:
0 All parameters of nominal accuracy
1 T or TD questionable
2 Flight-level winds questionable
3 SFMR parameter(s) questionable
4 T/TD and FL winds questionable
5 T/TD and SFMR questionable
6 FL winds and SFMR questionable
9 T/TD, FL winds, and SFMR questionable

Is someone going to do those maps this time?

[cycloneye]

pojo,do you have information about if the plane took of or not as no obs haved been released yet?

[Thunder44]

Is someone going to do those maps this time?

I might do them when they start descending.

By the way, no recon contest for invests, because I don't know if they will report back a VDM. The contests will start if this develops to a TD.

no idea... I'm back in Biloxi.
