台風による強風ハザードの評価：台風ノモグラムの開発

Abstract

The strong winds are observed over Japan, although the distribution is varied because of the mountainous terrain. The topography effect resulting in the strong winds associated with tropical cyclones (TCs) is intimately linked to the TC tracks. The purpose of this study is to examine the distribution of surface winds associated with TCs over Japan, based on numerical experiments. Using ensemble experiments with several TC cases, we detected the distribution of surface winds associated with TC tracks and developed a disaster-prevention graph so called “Typhoon Nomogram” at each location in Japan. The Typhoon Nomogram is useful for understanding the variability in the distribution of surface winds over Japan which depend on TC tracks and is useful for reducing the wind disasters caused by TCs.
