Wind data were obtained from NCEP CFSR, NASA MERRA, JRA-25, ECMWF Operational, ECMWF ERA40, and ECMWF ERA-Interim. Wave data were obtained in 1996 at three locations in the Black Sea within the NATO TU-WAVES project. The quality of wind fields was assessed by comparing them with satellite data. These wind data were used as forcing fields for the generation of wind waves. Time series of predicted significant wave height (H-mo), mean wave period (T-m02), and mean wave direction (DIR) were compared with observations at three offshore buoys in the Black Sea and its performance was quantified in terms of statistical parameters. In addition, wave model performance in terms of significant wave height was also assessed by comparing them against satellite data. The main scope of this work is the impact of the different available wind field products on the wave hindcast performance. In addition, the sensitivity of wave model forecasts due to variations in spatial and temporal resolutions of the wind field products was investigated. Finally, the impact of using various wind field products on predicting extreme wave events was analyzed by focussing on storm peaks and on an individual storm event in October 1996. The numerical results revealed that the CFSR winds are more suitable in comparison with the others for modelling both normal and extreme events in the Black Sea. The results also show that wave model output is critically sensitive to the choice of the wind field product, such that the quality of the wind fields is reflected in the quality of the wave predictions. A finer wind spatial resolution leads to an improvement of the wave model predictions, while a finer temporal resolution in the wind fields generally does not significantly improve agreement between observed and simulated wave data.eninfo:eu-repo/semantics/closedAccessBlack SeaSemi-enclosed basinsSWANWave predictionWind reanalysesWind wavesCoastal regionsPerformanceSwanImprovementAccuracyJra-25GrowthEngineeringOceanographyForecastingNASASensitivity analysisStormsWater wavesBlack seaSemi-enclosed basinsSWANWave predictionsWind waveExtreme eventPredictionSatellite dataSemienclosed seaSensitivity analysisSignificant wave heightWave modelingWind fieldWind waveOcean currentsArticle0003670233000162-s2.0-8494189701016117853Engineering, oceanOceanographyWave Energy; Wind Power; Data Buoy
