20th anniversary of the first operational synoptic surveillance mission with the NOAA G-IV

  On 14 July, 1997, Tropical Storm Claudette was moving northeastward offshore the east coast of the US.  Eager to test the new Gulfstream-IV (G-IV) jet aircraft and the new Global Positioning System dropwindsonde, the National Hurricane Center tasked the first-ever operational synoptic surveillance mission geared toward improving track forecasts. Initial condition differences in the […]

Two part paper on convective bursts in hurricanes published in Monthly Weather Review

These two papers analyze extreme upward air currents, called “convective bursts,” in hurricanes that have been believed to be important for hurricane intensification. We use the Weather Research and Forecasting (WRF) model to look at convective bursts in two hurricanes: Hurricane Dean from 2007 and Hurricane Bill from 2009. In the first paper, we study […]

60th Anniversary of Hurricane Audrey

In the morning hours of June 27, 1957, Hurricane Audrey sent a 12-foot (3.7-m) storm surge over Cameron, Louisiana, as the storm lashed the area with 125 mph (205 km/hr) winds. Many residents were caught by surprise and had not evacuated, and the storm took some 400 lives. Audrey was an unusual June storm.  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 […]
