Abstract
This study examined hindcast accuracy on numerical models of wind and waves during typhoons. By using meteorological objective analysis data GPV provided form Japan Meteorological Agency (JMA), the mesoscale model MM5 with typhoon bogus and data assimilation and 3rd generation wave model WAM, we estimated the wind and waves with high accuracy as compared to a parametric model such as 2D-typhoon model. Additionally, we obtained similar result by using GPV provided from National Centers for Environmental Prediction (NCEP) with a coarser spatial resolution than JMA's GPV though there were some problems to be solved. So the estimation model of wind and waves in this study is applied to hindcast high waves needed for computation of design wave.
