Abstract

Wind is the only driving force for all wave models and hence a wave model can only be as good as the wind field that drives the model. Ideally, wind specification must be such as to allow the important physical processes of wave generation, growth and dissipation to be appropriately represented in a wave model. In earlier discussions, three processes of the wave generation and growth were identified. These are: Phillips’ resonance mechanism, Miles’ shear flow mechanism and Hasselmann’s nonlinear wave-wave interaction mechanism. Further, according to recent studies, wave breaking is considered to be the most important dissipation mechanism over open ocean. In order for these processes to be suitably represented, wind specification on a meso- to micro-scale would be required over an ocean basin. Such a wind specification is rather ideal and cannot be attained on a routine basis at present.
