Abstract

The conditions under which abnormal waves occur in the western part of the Japan Sea and the northwestern part of the Pacific Ocean are examined. A numerical study of the abnormal waves was performed for a selected monsoon condition in winter. The mechanism of abnormal wave development is clarified using a wave spectrum model. It was found from the directional spectra that the effect of wind duration plays a key role in abnormal wave generation. For typhoon conditions, the relation between a standard project typhoon and the abnormal waves induced, is considered and the simulation method of the typhoon model is improved by introducing the typhoon stagnation effect. Finally, it was shown that abnormal waves generated by typhoons are due to long typhoon stagnation.
