UNCERTAINTY OF OCEAN WAVE HINDCASTS DUE TO WIND MODELING

Two wind models were developed and their results were compared with da ta gathered during the Wangara experiment, so as to characterize their uncertainty. One of the models was adopted to generate the wind field s used as input to a second generation wave model. The relative error in the wind speed was considered in order to assess the uncertainties of the predictions or the significant wave height. Different time step s for the wind input were also used to determine their effect on the p redicted significant wave height.
