Paper on the new basin-scale version of HWRF developed at HRD released online 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 changes to the intensity of tropical waves during the hurricane season released online in the Journal of Climate

African easterly waves (AEWs) are areas of low air pressure that move westward across North Africa and into the Atlantic Ocean. AEWs can cause intense thunderstorms, and, once over the warm waters of the Atlantic Ocean, they may become tropical cyclones that might affect the Caribbean and North America. In summer, many AEWs form in, […]

Paper on easterly waves in the Eastern Pacific that can form into tropical cyclones published in The Journal of the Atmospheric Sciences

“Easterly waves” are areas of low air pressure in the tropics that move westward and may become tropical cyclones. The most well-known type of easterly wave is the “African easterly wave,” which moves from West Africa north of the equator into the Atlantic Ocean and sometimes into the Pacific. Although almost all Northeast Pacific tropical […]

Paper on a new way to run forecast models with multiple hurricanes at the same time published in Weather and Forecasting

Summary: HWRF is NOAA’s primary model for tropical cyclone (tropical depressions, tropical storms, and hurricanes) forecast. The distance between places where forecasts are made in the model (the grid resolution) must be small to make accurate forecasts. However, the amount of computer power needed increases as these points get closer together. To save computer power, […]
