Paper on calculating and using wind speed and direction from the new NASA CYclone Global Navigation Satellite System (CYGNSS) released online in the Journal of Atmospheric and Oceanic Technology

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 …

Paper on combining satellite data and data from the Global Hawk aircraft to improve forecasts published in Weather and Forecasting

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 …

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

Paper on the potential impact of wind measurements from CYGNSS on forecasts published in Monthly Weather Review

Summary: The CYclone Global Navigation Satellite System (CYGNSS) was launched into space on December 15, 2016, to improve hurricane (tropical cyclone) forecasts by measuring wind speed on the ocean surface. Since the tropical cyclones mostly occur over oceans where other wind data are usually not available, the new observations can measure their wind speeds. This …

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 …

AOML and HRD researchers at 33rd AMS Conference on Hurricanes and Tropical Meteorology, Ponte Vedra, FL – 15-20 April 2018

Thirty-one AOML and HRD scientists participated in the recent 33rd AMS Conference on Hurricanes and Tropical Meteorology in Ponte Vedra, FL, as authors or co-authors on 65 presentations and 19 posters. Roughly 783 presentations (507 oral presentations in 67 sessions and 276 posters in 2 session) were submitted to the conference. Of the 567 TC-related presentations …
