A new coupled ocean-wave model has been developed and tested as a new component of the Coupled OceanAtmosphere Mesoscale Prediction System COAMPS . The modeling system is comprised of the Simulating WAves Nearshore SWAN wave model and the Navy Coastal Ocean Model NCOM. The models are two-way coupled using the Earth System Modeling Framework ESMF. The ocean model has been modified to incorporate the effect of the Stokes drift current, wave radiation stresses due to horizontal gradients of the momentum flux of surface waves, enhancement of bottom drag in shallow water, and enhanced vertical mixing due to Langmuir turbulence. The wave model ingests surface currents wave-current interaction and water levels. The system is designed to support the Navys ocean forecast requirements for regional and coastal domains. Validation studies for the Florida Straits and Virginia coastal area are presented. The system will run at the Naval Oceanographic Office and at the Fleet Numerical Meteorology and Oceanography Center.
