ESTIMATION OF TYPHOON-GENERATED MAXIMUM WAVE HEIGHT ALONG THE PACIFIC COAST OF JAPAN BASED ON WAVE HINDCASTING

Masataka Yamaguchi, Yoshio Hatada

Abstract


Wave hindcastings in the West Pacific Ocean and at selected locations along the Pacific coast of Japan by the use of two wave prediction models are conducted for 118 typhoons which occurred from 1940 to 1991 to estimate maximum wave height at each point during a typhoon. Combination with maximum wave height data in the concerned area for 125 typhoons from 1934 to 1983 obtained by Yamaguchi et al.(1987a, 1987c) results in data sets of maximum wave heights caused by 243 typhoons from 1934 to 1991. Spatial distribution of the most extreme wave height and wave height for return period of 100 years, and their variation along the Pacific coast of Japan are re-examined on the basis of statistical analysis of the data and compared with the Yamaguchi et al. results (1987a, 1987c), in which case there is little change in the distribution except for the Western Kyushu coast. In addition, maximum wave height along the coast of the Japan Sea is evaluated in a similar manner.
