Research Abstract

This study investigates developmental mechanism of locally strong winds and air mass transformation associated with summertime cool easterly wind, called in Yamase in Japan, and winter monsoon by regarding the Tsugaru Strait, Mutsu bay, and the surrounding region as one system. In terms of distribution and structure of the strong winds, representative atmospheric fields inducing the strong winds, and interannual variation of the strong wind occurrence, this study is the first to show characteristics of the surface winds within and adjacent to the Tsugaru Strait.
