Abstract
It is the purpose of this paper to develop the forecast method of wind disasters based on the topographical analysis. In the first place, we analyze the topographical structure of the regions which became the object of this study with some topographical factors, and construct the landform classification map. Secondly, we dicide the dangerous condition of each region in the landform classification map according to the direction of the wind. In the present paper, we try to forecast wind disasters on Hachijo Island, Okinoerabu Island and Ishigaki Island, and the basic results for the forecast method of wind disasters were obtaind with the topographical classification system.
