The present study aims to improve the accuracy of forecasted wind and wave data generated by a wind-wave forcasting system over the entire Persian Gulf and Strait of Hormuz. A forecasting system has been developed and calibrated for winds and waves in the study area based on available observations. The performance of the developed forecasting system is favorably in agreement with the measured data; however, the model has deficiencies in capturing extreme events in certain situations. Hence, the simulated wind data are modified using a corrective method to obtain an optimum correlation factor between the simulated results and observations. This set of data is adopted as the input for the 3rd generation WaveWatch III wave model to simulate a new set of forecasted wave data. The output wave data are compared with the observations to evaluate the accuracy of the simulated wave estimations over the Persian Gulf.
