Abstract

In recent, years, the number of wave prediction models has proliferated. These models range from relatively simple parameterizations of significant wave height as a function of wind, duration and fetch to rather sophisticated solutions for the generation, propagation and dissipation of two-dimensional wave spectra. It is sometimes suggested that any wave model will provide reasonable answers when properly applied, and that most of the deviations between measured waves and predicted waves can be explained by discrepancies between actual and estimated wind fields. Although almost certainly much of the error in wave prediction is related to problems in determining a wind field, this paper examines the specific question of whether or not there are differences among these models such that even if the wind field were perfectly specified, there would remain significant deviations among predicted waves. First, wave generation under uniform wind fields are compared using nondimen-sional parameters.. Then, the models are again compared under conditions of time varying, space varying wind fields and with irregular fetch boundaries. It is concluded that, in the open ocean with long duration, slowly varying weather system, most models produce rather similar results; however, near a coastal or in regions with rapidly varying weather systems rather marked differences can be expected from the use of different models.
