Abstract : The Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS) developed in the Marine Meteorology Division at the Naval Research Laboratory, was transitioned to Fleet Numerical Meteorological and Oceanographic Center (FNMOC) in September 1996, for evaluation as the next generation mesoscale forecast model for the Navy. The system allows multi-level grid nesting and has explicit treatment of precipitation and boundary layer effects to provide forecast of meso-alpha and meso-beta scale phenomena. The configuration of the system can cover a large domain with high resolution in the central region that is suitable for tropical cyclone forecasting such as the case presented here for Supertyphoon Herb that hit Taiwan island and caused severe damage. Performance of the COAMPS on the track forecast, wind and precipitation forecast, and interaction of the typhoon with topography is evaluated and analyzed.
