Abstract

An evaluation of the Global Forecasting System (GFS) and Navy Operational Global Atmospheric Prediction System (NOGAPS) forecasting skill of tropical cyclogenesis is presented. To better determine how successful the GFS and NOGAPS modes are at anticipating tropical cyclogenesis, the percentage of successful forecasts of all tropical lows are examined for the 2003 season. Preliminary analyses of Tropical Storm Bertha show that both the GFS and NOGAPS anticipated development in the northeastern Gulf of Mexico. The GFS model is also found to have a much stronger vortex at 72 hours than the NPGAPS counterpart.
