Mediterranean Sea Waves Analysis and Forecast (Copernicus Marine Service MED-Waves, MEDWAΜ4 system)

The Mediterranean Sea Waves Analysis and Forecast system is composed by hourly wave parameters at 1/24º horizontal resolution covering the Mediterranean Sea and extending up to 18.125W into the Atlantic Ocean. Med-Waves modelling system is based on WAM Cycle 6 wave model and resolves the prognostic part of the wave spectrum with 24 directional and 32 logarithmically distributed frequency bins, while model solutions are corrected by an optimal interpolation data assimilation scheme of along track satellite significant wave height observations. The atmospheric forcing is provided by the operational ECMWF model. The wave model is forced with hourly averaged surface currents and sea level obtained from CMS Med MFC at 1/24° resolution. The wave system includes 2 forecast cycles providing Mediterranean wave analysis and 10 days of wave forecasts.
