Cycloneye is the mission of the Global Hawk continues or is ended?
Thanks .

Thanks .

Still flying in the area but no data yet.

Latest animated VIS GIF showing convection filling in nicely this afternoon. Looking better:

[Miami Storm Tracker]

Was that an eddy at 15.5 and about 64 or did the llc just get pulled into the storms building around it. Looking a bit less elongated than earlier, and maybe even a little feeder pulling in for the south.

[ronjon]

The LLC is quite vigorous and all it needs to be a TD is more persistent convection.

Ok, so we should have to wait a bit before having the final results.

850 vorticity really tightening up now. Check out the difference three hours make. Vorticity to the NE also a little stronger but is only low level right now nothing at 500mb. I think the SW vorticity is going to win out.

Could NHC upgrade this to a TD based on data from the Global Hawk mission?
I'm NOT saying it is a TD now but I'm just curious.

Looks like convection is increasing but isn't it getting close to DMIN?

What a difference a day makes! We may have a TD at 11pm tonight.

This Global Hawk mission don't release data like the Air Force recon.



HIRAD is a multi-frequency, hurricane imaging, interferometric single-pol passive C-band radiometer, operating from 4 GHz to 7 GHz, with both cross-track and along-track resolution that measures strong ocean surface winds through heavy rain from an aircraft or space-based platform.


HIWRAP (High-Altitude Imaging Wind and Rain Airborne Profiler) is a dual-frequency radar (Ka- and Ku-band), dual-beam (300 and 400 incidence angle), conical scan, solid-state transmitter-based system, designed for operation on the high-altitude (20 km) Global Hawk UAV.


The Airborne Detector for Energetic Lightning Emissions (ADELE) detects gamma-rays and relativistic electrons associated with lightning and thunderstorm charging. The primary scientific target is terrestrial gamma-ray flashes (TGFs), brief (< 1 millisecond), extremely bright bursts of high energy radiation that have mostly been detected from satellites in low Earth orbit.


The High Altitude Monolithic Microwave integrated Circuit (MMIC) Sounding Radiometer (HAMSR) is a microwave atmospheric sounder developed by JPL under the NASA Instrument Incubator Program. Operating with 25 spectral channels in 3 bands (50-60 Ghz, 118 Ghz, 183 Ghz), it provides measurements that can be used to infer the 3-D distribution of temperature, water vapor, and cloud liquid water in the atmosphere, even in the presence of clouds.

Thanks Cycloneye.

I am just glad it is moving now. The past day and half was certainly frustrating to watch.

[NDG]

Pressure down to 1008mb at buoy 42060 just north of 97L

Have to agree. What a difference! Has the look it is going to develop. Land interaction will be it's biggest problem as the environment looks good for development (finally).

Got to think NHC will up the 2-day development chances again at 8pm EST outlook and we should see "code red" here.

Could get a depression to form pretty quickly now with the good environment and we may have one by 11pm EST tonight.

Well pressures are certainly falling now.

I'm confused, did the AF fly today or not.
