Paper on the new basin-scale version of HWRF developed at HRD published in Weather and Forecasting

The Hurricane Weather Research and Forecasting Model (HWRF) has become an important tool for both hurricane forecasters and researchers. The current HWRF has three domains around only one tropical cyclone. Its inner domain makes forecasts on a grid with points 2 km apart and follows the tropical cyclone during the forecast. During hurricane season in […]

Paper on a preliminary test of the impact of data from a new satellite published in the Marine Technology Society Journal

Summary:  The new National Aeronautics and Space Administration CYclone Global Navigation Satellite System (CYGNSS) measures wind speed on the ocean surface. Because hurricanes happen over oceans where other wind data are usually not available, these new observations may be useful in pinpointing their positions and intensities. This study examines whether CYGNSS wind information will improve […]
