Abstract :
Operational forecasts of significant wave height and period produced by the Naval Oceanographic Office (NAVOCEANO) were compared to wave height measurements obtained by the Topography Experiment (TOPEX) altimeter data. Comparisons were made between the satellite measurements and the forecast wave heights for forecast periods of 12, 24, 36, and 48 hours. The Spectral Wave Prediction System (SWAPS) operated by NAVOCEANO consists of a coupled system which includes a third-generation spectral wave model (WAM), shallow-water wave transformation models, and a harbor response model. This paper evaluates the forecast performance of only the WAM component of SWAPS implemented at a resolution of 28 km. The areas evaluated include the Mediterranean Sea, Red Sea, and the Arabian Gulf. The overall performance of the model is shown to be satisfactory for Navy operations
