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.
