45th Anniversary of Hurricane Agnes

On June 19, 1972, a minimal Category-One hurricane named Agnes came ashore near Panama City, Florida.  While wind and storm-surge damage along the coast was small, the major impact from Agnes came afterward. Agnes developed from a disturbance over the Yucatan peninsula on June 14th.  As the system drifted eastward over the Yucatan Channel, it […]

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 […]

Book chapter on monitoring tropical cyclones with the Synthetic Aperture Radar published

  Satellite images taken from an instrument called the Synthetic Aperture Radar (SAR) that can see things on the earth’s surface that are about 100 m (300 ft) across are used study the wind in tropical cyclones. The SAR can see small swirls (called vortices) near the eye of the hurricane, small long, thin lines […]
