An Evaluation of the Numazu Operating Area and Kagoshima Harbor, Japan, as Typhoon Havens

Abstract

This study evaluates the Numazu Operating Area and Kagoshima Harbor as possible typhoon havens. Characteristics of the areas under tropical cyclone conditions, including climatology, topographical effects on the wind, and wave action at each location are discussed. Problem areas to be considered if remaining in the operating area/harbor and suggested evasion procedures for ships are examined. The tracks of tropical cyclones from 1947-1974 for the western North Pacific were analyzed to assess the threat posed to each area by a tropical cyclone. Results show that neither area is an entirely safe haven. The Numazu Operating Area could be a haven under certain specified conditions but only as a last resort. Kagoshima Harbor should never be considered a typhoon haven.
