During a test flight on 31 July, the NOAA Aircraft Operations Center (AOC) released a dropwindsonde and transmitted the wind, pressure, temperature, and humidity data to the ground and around the world via the Global Telecommunications System. Since the advent of dropsondes in the 1940s, only data from a few of the many observations could […]
Summary: The warm ocean provides the energy for tropical cyclones to form and intensify. Knowing what is happening in the air immediately above this warm ocean (called the boundary layer) tells us how that energy gets into the air. So, it is important to know what is happening there to accurately predict how strong a […]

Summary: The NASA CYclone Global Navigation Satellite System (CYGNSS) measures wind speed, but not direction, at the ocean surface. To test the impact of new observations before such a satellite system is launched, observations like those from the satellite are created from a weather model. This study uses these “simulated” observations to learn how to […]
Summary: Because satellites are observing the weather all the time, there are almost always satellite data available around hurricanes or tropical cyclones (TCs). On the other hand, Hurricane Hunter aircraft can only reach TCs when the storms are near land and when airplanes and crews are available. When Hurricane Hunter missions are planned, the regular […]
On July 27, 1943, U.S. Army Air Forces Lt. Col. Joseph B. Duckworth made the first deliberate flight into the eye of a hurricane. This historic event inaugurated the era of aircraft reconnaissance into tropical cyclones which greatly enhanced our understanding and forecasting of these storms. Duckworth was an Eastern Air Lines pilot prior to World War […]
HRD researchers discussed the results from the 4 P-3 missions into AL03 Tropical Storm Chris (8-9 July 2018). The agenda for the discussion was: Missions Overview (Jon Zawislak) Mission Summaries 20180708H1 TDR (Kelly Ryan) 20180708H2 TDR (Hui Christophersen) 20180709H1 TDR (Kelly Ryan) 20180709H2 TDR (Gus Alaka) Discussion Slides from the debrief are available at: ftp://ftp.aoml.noaa.gov/pub/hrd/blog/meetings/2018/HFP/2018HFP_Chris_Debrief.pptx
