WAVE MODELLING: FUNDAMENTAL ASPECTS OF OCEAN WAVE MODELLING FOR APPLICATION IN A THIRD GENERATION MODEL

Objective


Investigations have been made on the influence of wind field generation on wave forecasts. It was found that different institutions come to different windfield patterns for a specified time and area. A comparison was made of the wave models HYPA and WAM applied to several selected storms in the North European shelf area which included deep water and shallow water conditions. In general it was found that satellite values for significant wave height and both wave model results agree fairly well. The wind speed measurements derived by the radar altimeter are too low in comparison to the ocean winds especially in strong wind situations. A new numerical model has been developed to determine the optimum route for a ship under the economic criteria of minimum total voyage costs.
In recent years the European wave modelling community has developed a new third generation wave model (WAM). This model, based on physical principles, compares favourably with existing second generation models To make further progress, it is necessary to get a better insight in the air-sea and sea-bottom interaction processes, that determine wave growth and attenuation. Fundamental research into these processes will lead to a better parametrization of the source terms in the wave model and thus to a better performance. In the proposed research an important role will be played by data assimilation, enabling the use of ERS-1 satellite data.
