Abstract :In the study, the performance of the MIKE 21 SW insert ignore into journalissuearticles values(Spectral Wave); model using the three different wind fields, namely ERA-Interim, ERA5, and CFSR was evaluated in the Eastern Mediterranean Sea. Model results were calibrated with four buoy measurements by tuning physical model parameters. Wave simulations showed a strong sensitivity to the whitecapping parameter insert ignore into journalissuearticles values(Cds);. Calibrated MIKE 21 SW model run to validate at two buoy measurements. Considering the statistical error measures: insert ignore into journalissuearticles values(i); ERA-I predicted lower significant wave heights and wave periods than ERA5 and CFSR, insert ignore into journalissuearticles values(ii); statistical error measures insert ignore into journalissuearticles values(bias, RMSE, and SI); obtained with CFSR were calculated slightly higher than those obtained using ERA5 insert ignore into journalissuearticles values(iii); ERA5 performed slightly better in the hindcast of Eastern Mediterranean wave properties than ERA-I. As a result of all evaluations, the highest correlation coefficient insert ignore into journalissuearticles values(R);, relatively low statistical error measures, and slightly better accuracy were provided by the model settings forced with ERA5 wind fields.
