Аннотация: In this study the third generation spectral wind-wave model SWAN was used for simulations. For wind input data two types of wind reanalysis were chosen: NCEP/CFSR with 1-hour time step and NCEP/NCAR with time step of 6 hours. The final computational grid for rectangular mesh for the Baltic Sea is 0.05×0.05◦ . The simulated data were compared with instrumental data of the Sweden buoys and of the acoustic wave recorder fixed at the Russian oil platform. The results reveal that for the Baltic Sea it is more efficient to use rectangular mesh for the deep open area and irregular mesh near the coast. Simulations using wind data from NCEP/NCAR significantly decreases the quality of the results compared with NCEP/CFSR wind data: Bias increases in 10 times (-0.730), RMSE - in 2−3 times (0.89).
