Abstract

 Dynamical downscaling experiment of JRA55 for Typhoon Vera (Isewan Typhoon) using WRF was carried out. At First, the reproducivilities of five global reanalysis data for Typhoon Vera were compered, and it was shown that JRA55 has highest quality. There are some papers of the dynamic downscaling method for storm surge hindcast. In this study, domain size and resolution of the coarse domain were considered. The coarse domain size influences the typhoon route and central pressure, and large domain estimates large error of typhoon route and stronge typhoon. Threshold is whether the coarse domain fully includes the area of wind speed more than 15 m/s around the typhoon. On the other hand, the resolution of the coarse domain doesn't affect the typhoon route, and affect the typhoon strength.
