AB: Real-time forecasts with the Operational (FNMOC) and high-resolution Experimental (NRL-MRY) versions of the Navy Coupled Ocean Atmosphere Prediction System (COAMPS) were generated during the July 2001 Hyperspectral Coupled Ocean Dynamics Experiment. The oceanographic experiment centered on the New Jersey coastline at the Rutgers University Long-term Ecological Observatory (LEO) located in Tuckerton, NJ. The ensemble of Navy forecasts and standard NOAA forecasts were used to plan aircraft and shipboard operations, and to drive the Regional Ocean Modeling System (ROMS). The higher spatial and temporal resolution of the Experimental COAMPS showed a substantial improvement in the accuracy of forecast wind speed and direction, temperature, and relative humidity during the eight cycle experiment. Both the Operational and Experimental versions of the COAMPS model showed approximately equal skill in resolving synoptic scale features such as low-pressure areas associated with frontal systems. The high-resolution Experimental COAMPS performed exceptionally well in forecasting the variations and movement of mesoscale phenomena such as the New Jersey coastal sea breeze. The substantial gains of the higher spatial and temporal resolution at the mesoscale level, combined with the negligible losses in the resolution of larger scale atmospheric phenomena, indicates the Experimental COAMPS was a valuable tool for guiding research activities during the HYCODE experiment.
