Comments:Second flight against hurricane Karl in the Atlantic. 81 sondes deployed. Global Hawk Completes Flight Over Karl with other "Hurricane Hunters" SHOUT 2016 Science Flight #6 conducts multi-aircraft mission above and around Tropical Storm Karl. NOAA UAS Program's Sensing Hazards with Operational Unmanned Technology (SHOUT) Team launched the NASA/NOAA Global Hawk over Tropical Storm Karl at 1447 EDT 24 September after a 20.5 hour turn-around from the last flight. With the mission to sample Tropical Storm/Hurricane Karl as it tracks rapidly off to the northeast following its turn near Bermuda, the crew hoped that this event would record Karl during intensification to hurricane strength. This sixth SHOUT science flight is being conducted in continued close coordination with the National Hurricane Center, Hurricane Research Division and the manned Hurricane Hunters including conducting inter-comparison formation flight tracks with NOAA WP-3 and G-IV. From the 11 PM September 24th National Hurricane Center (NHC) discussion, "Karl continues to produce a large area of cold-topped convection to the northeast of the center. However, data from the NOAA P-3, NOAA G-IV, and the NASA/NOAA Global Hawk aircraft indicate that the circulation is losing definition as the cyclone accelerates toward the northeast. The initial intensity of 55 kt is based on a combination of dropsonde, flight level, and SFMR winds from the three planes, and the central pressure of 992 mb is based on data from a Global Hawk dropsonde." This will be the second flight into Karl providing a nice connection between our first flight and later planned sampling by the North Atlantic Waveguide and Downstream Impact Experiment (NAWDEX) team after it undergoes ET and tracks toward Europe. The overarching scientific aim of NAWDEX is to increase the physical understanding and to quantify the effects of diabatic processes on disturbances to the jet stream near North America, their influence on downstream propagation across the North Atlantic, and consequences for high-impact weather in Europe. The field campaign will provide a unique observational dataset, sampling the key dynamics and processes associated with the triggering, propagation and downstream impact of disturbances along the North Atlantic waveguide. This final flight over Karl landed at ~1333 EST 25 September after a 23 hours flight and launching 81 dropsondes.
