Irene Recon Reports

[cycloneye]

First Mission at 2 PM EDT.

[storms in NC]

Now will they be leaving at 2pm or geting there at 2pm

[USCG_Hurricane_Watcher]

First Mission at 2 PM EDT.

Is this the USAF flight out of Keesler or the NOAA flight out of MacDill?

[Hyperstorm]

First Mission at 2 PM EDT.

Is this the USAF flight out of Keesler or the NOAA flight out of MacDill?

You got it correct. USAF from Biloxi, NOAA from Tampa. They will be in the storm just before 2pm for a fix at that hour...

[EDR1222]

Will be interesting to see if they find a stronger storm.

[x-y-no]

Looks like the NOAA flight has been shifted to later (takeoff at 2pm). If true, that's too bad since the environmental data won't be in 0Z run of the models.

HOLA Luis!! Hope you enjoyed your birthday dinner last night!!

Can you please put up an offical thread for 96L, on a sticky? LOL, sounds funny, huh?

How do you figure? Data dump for the 00Z run of the GFS does not take place until 0300Z / 11 PM EST.

[Derek Ortt]

the later starts to the G-IV flights is to keep the sondes from going into the 18Z runs, or I should say half into 18Z and the other half into 0Z. This createst asymmetries which actually makes the forecasts worse

OK ... that makes sense. Thanks Derek.

They get to 74W and transmission stops...no reports for 50 minutes now...

I thought one plane was gonna check Irene and the other from NOAA was gonna check the weather conditions around irene, then they were gonna feed this info to the models, and I thought it odd that 2 planes were going for 2 differant reasons for the same system

is all of this because the models are having a heck of a time with Irene?
They don't generally send 2 do they?

This is what I heard...AF has the storm, NOAA has the surrounding areas...We'll see I guess.

No, this is typical for a storm relatively close to the U.S. The planes have separate missions. The WC-130 (the Air Force plane) flies at low levels to fix the center and get the wind and pressure obs from inside the storm. The Gulfstream-IV flies at high altitude in the area around the storm to release dropsondes that collect upper-air data (that as you correctly state) gets fed into the models. Each plane is doing the mission that it is designed for.

[Frank2]

No, the AF flight is the operational one, and the NOAA flight a operational/research mission.
