Wave forecast
The operational wave forecasting system is named WW3MED and it is based on WAVEWATCHIII (v6.07). The system consists of a model at the horizontal resolution of 1/32° covering the entire Mediterranean Sea, and nine nested grids chosen in the Italian seas at the horizontal resolution of 1/128°. The forcing, represented by the surface wind components, is provided by the operational weather forecast system SKIRON by the University of Athens; lateral conditions for the higher resolutions domains, which consist of bidimensional wave spectra, are derived from the Mediterranean simulation. Bathymetry has been generated from the General Bathymetric Chart of the Oceans (GEBCO_2021), which provides global elevation data on a 15 arc-second grid.
The forecasts run daily over five days, and the results are available on each grid hourly
