Summary:Knowing what is happening in the boundary layer of a hurricane (the area from the ocean surface up to about 1 km height) is very important for making accurate forecasts of how strong the hurricane will get. But measuring temperature, moisture, and wind so close to the ocean surface is dangerous and difficult. In the …
Paper on the direct measurement of important air-sea interaction parameters in tropical cyclones published in the Journal of Geophysical Research
Summary:Friction is what happens when two things rub up against each other; when this happens, they release heat. When this happens in the atmosphere, we call it “dissipative heating.” Tropical cyclones (TCs) mainly gather energy from the warm ocean at the boundary layer, the region from the surface of the ocean to an altitude of …

Paper on the new Doppler Wind Lidar on the NOAA Hurricane Hunters published in Remote Sensing
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 …
HRD Debrief for missions into Tropical Storm Chris – 19 July 2018
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

HRD Seminar – Prof. Mark Bourassa, Florida State University, Tallahassee, FL – 25 June 2018
Prof. Bourassa presented a seminar titled “Ocean Applications of Satellite Measurements of Winds and Currents Through Ka-Band Scatterometry”. ABSTRACT: Ka-band scatterometry is of great use for a wide range of applications, and can be used to measure ocean surface winds and surface currents at relatively high resolution compared to traditional scatterometry. The sensitivity to wind direction …
