Prediction of Sea Surface Wind Distribution with a Three Dimensional Wind Model

Abstract

In late years 3 dimensional non-linear wind prediction model that a result of high precision is provided are put to practical use. When we predict wave, it is often that we adopt SMB method in a closedown sea area like a bay. It is the fact that sea surface wind of that case converts AMEDAS data of a neighborhood by a simple coefficient by a geographical condition. However, an observation spot of wind in the inland strongly takes influence of the neighboring topography. Therefore, it is thought that it becomes a cause to lose precision of wave prediction to use a uniform coefficient. If a place of wind is correct, as for the wave prediction by SMB method, practical precision is provided. Thus, We suggest a method to predict sea surface wind in 3 dimensional non-linear wind prediction model.
