Description WAM cycle 4 third-generation wave model Spatial resolution = 0.5 degree The wind forcing: ECMWF and NCEP/NCAR global reanalysis Grid: spherical grid (31X14 sea grid points) Integrated parameters and total sea and swell spectra output are obtained at every 3 hours Coverage Entire Black Sea basin: grid from 27.5E to 42E and from 41.0N to 47.0N (31X14 grid points) Validation The model is adapted for fetch-limited conditions and validated against buoy measurements in several points around the Black Sea and satellite data. Implementation Hindcast Time span: 01/01/1948 – 30/06/2009 Wave regimes: wind sea, swell Wave output parameters for wind sea, swell and total sea Hs – significant wave height Tm – mean wave period Tp – peak wave period Theta – mean wave angle
