Abstract
From 16 to 18 December 2014, a storm surge induced by an explosive cyclone struck the city of Nemuro causing immense damage due to flooding. This explosive cyclone was rapidly intensified along the east coast of Tohoku region and remained stationary near the Nemuro Bay. The central pressure reached 946hPa and significant sea level rise was observed. It is expected that explosive cyclones, which are strengthened with latitude, cannot be ignored in flood prevention in northern Japan region. In this study, the path of explosive cyclone and central pressure in the past decades are analyzed and compared with those of typhoons which was considered as meteorological external force in flood prevention law. Furthermore, we discuss the synoptic meteorological fields in which persistent explosive cyclones occurred in northern Japan.
