ATL : TROPICAL DEPRESSION ALEX - RECON DISCUSSION

[cycloneye]

This thread is for the members to discuss about the data that all the missions that NHC will have for this system,to then not interrupt the flowing of data in the main recon thread.

[KWT]

Recon reports looking pretty impressive it has to be said, I think the low pressure is more a reflection of the general low pressures present in the basin right now, like 2005 in some respects...

Advertised by ECMWF months ago in their monthly MSLP updates. With the data available,I say Alex at 11 PM.

thank you!!!!

(I can't get a smilie to post - the bowing down to you one so play like it is here)

when is the next flight guys?

[HURAKAN]

when is the next flight guys?

FLIGHT TWO - TEAL 71
A. 26/0600Z
B. AFXXX 0201A CYCLONE
C. 26/0200Z
D. 18.0N 84.5W
E. 26/0500Z TO 26/0900Z
F. SFC TO 10,000 FT

I wonder whether they will fly, I heard they don't tend to fly unless its a hurricane at night time?

Unless we get a major blow up directly over head I would not mind them waiting but, it's not that far..Waiting for them to task a Jet for above 10,000ft..more good model data.

For the new members that may not know,200z is the departure from the base, or 10:00 PM EDT.

How long will it take for them to reach the storm once they depart?

[RL3AO]

How long will it take for them to reach the storm once they depart?

2 1/2 to 3 hours I think.

They'll go. Tropical cyclone threatening land. Its their job.

[KWT]

Ah fair enough RL3AO, I just remember Derek saying before they typically won't go into a system at night unless its a hurricane, of course the fact it is rather close to land probably means this maybe one of the times they do go...

[clfenwi]

How long will it take for them to reach the storm once they depart?

It's 885 nautical miles from Keesler Air Force Base to the 5 PM position of the storm. Plane flies at around 310 knots, so it would take a little less than three hours to get there.

As for your question, KWT, you may be thinking of low level invest flights like this afternoon's. Those are only done during daylight hours. For established tropical cyclones, they do fly at night, at a higher altitude.

You could be right, but I seem to remember them not flying into invests at night.

[KWT]

Well given two people have said the same thing I'd assume your right on this case.

Still I expect if recon does go in there tonight I'd expect something around 40kts possibly even a touch higher given that convective bursting occuring right now.

where's pojo when we need her?

[BZSTORM]

so is recon still on for departure 10pm EST? I think thats 8pm BZ time so by my clock 4mins time??

[mf_dolphin]

Recon just departed Biloxi.

The Gulfstream IV-SP (G-IV) is a high altitude, high speed, twin turbofan jet aircraft acquired by AOC in 1996. The G-IV is currently configured for operational support of the National Hurricane Center synoptic surveillance mission and is expected to provide support for NOAA programs for many years to come. This mission is designed to collect, process and transmit vertical atmospheric soundings in the environment of the hurricane. The principle tool used for this task is the GPS dropwindsonde.

The dropsonde is released from the G-IV measuring and transmitting back to the aircraft the pressure, temperature, humidity, and GPS Doppler frequency shifts as it descends to earth. The Doppler shifts are used to compute the horizontal and vertical wind components. After analysis and processing of the dropsonde data the information is formatted into a TEMP-DROP message using the standard WMO format. The TEMP-DROP message is then transmitted to the National Centers for Environmental Prediction and the National Hurricane Center for inclusion into the global and hurricane model runs. The TEMP-DROP message is also provided to the hurricane forecaster providing real-time observations depicting the synoptic patterns surrounding the hurricane.

So when can we expect them to task The Gulfstream?
