鈴鹿山脈周辺の降雨について

Abstract

Analyzing the detailed data on rainfall during the warm season for three years (1967-1969)which include the data of our own observations around the the Suzuka Mountains and other me-teorological elements, a few characteristic features of the heavy rainfall were clarified with someproblems concerning them were revealed.In the case of heavy rainfall in which the maximum 24-hour precipitation was about 200 mmor more, strong easterly wind prevailed in the lower troposphere, the middle and lower tropo-sphere was nearly saturated with water vapour, and the static stability was nearly neutral. Theheavy rainfall area around the mountains shifted more or less westward according to the easterlycomponent of the wind in the upper troposphere. Such eontribution of the upper wind to the orog-raphic rainfall was theoretically considered after the dynamical model proposed by Sarker (1966).Comparing the results with the observation, it was suggested that our consideration wasrealistic.
