ESTIMATION CHARACTERISTICS OF THREE THIRD GENERATION WAVE HINDCASTING MODELS FOR TYPHOON LAN

Abstract

 In Typhoon Lan which came to Japan in 2017, disaster occurred in a wide area on the coast of Japan and long waves were observed in Tokyo bay. In this study, we estimated the wave field generated by the typhoon Lan using three kinds of third generation wave hindcasting models (WAVEWATCH III, SWAN and WAM). Then, the estimation characteristics of three models were clarified by using the contour map, the time series, and the directional spectrum of the wave conditions of the coastal area.
