Review of downslope windstorms in Japan

Hiroyuki Kusaka and Hironori Fudeyasu

Abstract

In Japan, at least 28 local winds are known by name, most of them associated with downslope windstorms and gap winds. To review these windstorms, we categorize them based largely on the atmospheric conditions and formation mechanisms, and then focus on representative examples. These representative cases include the \"Yamaji kaze\", a typical downslope windstorm, the \"Hirodo kaze\", a downslope windstorm induced by a nearby typhoon (intense tropical cyclone), and the \"Karak kaze\", a downslope wind with a clear diurnal variation. Other downslope winds such as the \"Inami kaze\" and the gap wind \"Kiyokawa
