SHOUT 2016 Hurricane Rapid Response Executes Science Flight #5 Above KARL

NASA/NOAA Global Hawk recovered at NASA Wallops, VA after a 24 hour mission supplying multi-sensor real-time data to the National Hurricane Center with 82 sondes deployed.

The NOAA UAS Program’s SHOUT launched the NASA Global Hawk at 1813 EDT September 22nd recovering at 1813 EDT September 23rd after conducting a multi-aircraft mission above Tropical Storm Karl. According the the National Hurricane Center (NHC), Karl has the opportunity to strengthen during the next couple of days while it is moving over warmer water and relatively low shear as it approaches Bermuda and turns North. The Bermuda Weather Service has issued a Tropical Storm Warning characterizing Karl as a “threat” with its closest point of approach to Bermuda to be 50 nm to the SSE at 0400 AST on Saturday, September 24th.

Fixes from several reconnaissance planes including the Global Hawk (red track), WC-130s, WP-3 (blue track), G-IV and satellites show the core of Karl closing in on Bermuda in about 24 hours. The team closely coordinated with the manned aircraft for sonde drops and to conduct inter-comparisons between the Global Hawk’s High-Altitude Imaging Wind and Rain Airborne Profiler (HIWRAP) and the WP-3’s Imaging Wind and Rain Airborne Profiler (IWRAP) above the storm. The JPL’s High Altitude Monolithic Microwave integrated Circuit (MMIC) Sounding Radiometer (HAMSR) is a microwave atmospheric sounder onboard the Global Hawk.

The SHOUT team is scheduled for a minimum turn-around take-off for science flight #6 at 1500 EDT on Saturday, September 24th in coordination with German, Swiss and US North Atlantic Waveguide and Downstream Impact Experiment (NAWDEX) which is currently flying manned aircraft from Iceland.
