Outline of Final Research Achievements

Due to change the horizontal place of generation and intensity of snowfalls by passing route of cyclones, it is difficult to understand the actual status of extreme snowfall phenomenon in the areas of the Pacific Ocean. In this study, spatio-temporal fluctuations of snow depth distribution were analyzed in a climatological context to assess the regional characteristics of snowfall amount and intensity after the cyclone passage the south coast of Japan. The result demonstrate the annual frequency of heavy snowfall varies depending on the areas, and the gradient of snow depth distribution of on the mountain tends to be smaller than those of the area facing the Sea of Japan.
