Paper on the impact of ocean surface waves in intensity forecasts published in The Journal of Geophysical Research Oceans

Ocean surface waves affect the exchange of momentum and energy between the ocean and the atmosphere.  However, the impact on tropical cyclone intensity and structure in fully coupled numerical models has not been well-understood. This study used a regional atmosphere-ocean-wave coupled model to study the wave impacts.  Simulations of 21 real tropical cyclones were conducted. … Continue reading Paper on the impact of ocean surface waves in intensity forecasts published in The Journal of Geophysical Research Oceans

Recap of Julia and Lisa flights

NOAA conducted two flights into Julia and five into Lisa during October of this year, all in the Caribbean Sea. The main purpose of all the missions was to gather Doppler Radar and dropwindsonde data for ingestion into NOAA's computer models to improve forecasts. Flight tracks of missions into Julia (left) and Lisa (right) during … Continue reading Recap of Julia and Lisa flights

HRD scientists attend Hurricane Forecast Improvement Program Annual Meeting

Last week, researchers from HRD attended the 2022 Hurricane Forecast Improvement Program (HFIP) Annual Meeting in Miami, Florida.  Group photo of some of the participants of the 2022 HFIP Annual Meeting, both in person and virtually.  The primary objective of this meeting was to discuss key HFIP strategies including advances to NOAA's next-generation Hurricane Analysis and Forecast … Continue reading HRD scientists attend Hurricane Forecast Improvement Program Annual Meeting

Hurricane and Ocean Testbed Technical Workshop

NOAA P-3 data and satellite imagery overlain during a mission into Lisa. Data from the Imaging Wind and Rain Airborne Profiler (showing wind and rain directly below the aircraft), Tail Doppler radar (measuring wind speed and direction throughout the storm), Wide-Swath Radar Altimeter (wave height below the aircraft), and flight-level instruments are all shown. During … Continue reading Hurricane and Ocean Testbed Technical Workshop

Recap of Hurricane Ian flights

In September, NOAA conducted 15 missions in and around Hurricane Ian before its historic landfall in Florida. Among these were 8 P-3 missions and 7 synoptic surveillance missions conducted by the G-IV. One hundred forty-three dropwindsondes were released along with 18 Airborne Expendable Bathythermographs to measure profiles in the atmosphere and the ocean underneath Ian. … Continue reading Recap of Hurricane Ian flights
