Abstract
GSM (Global Spectral Model). A climate distribution data set by JMA (Japan Meteorological Agency) is applied to the wave and storm surge estimation for explosive cyclones and typhoons. Wind and atmospheric pressure conditions for the wave and storm surge estimation are obtained using two methods involving the GSM data set. One way is that the GSM data set is linearly interpolated while another is an empirical typhoon model based on the data set. The main results are summarized as follows; when linear interpolation is used in estimations of meteorological fields, it shows high correlation with long-term waves due to bomb low pressure. On the other hand, when using a typhoon model to estimate the weather field, it was confirmed that this method yields high accuracy to the peak value of local typhoon-generated waves.
