余部峡谷における局地的強風の性状について

Abstract

Characteristics of local strong wind in Amarube area were studied from the results of a wind survey for three years in this area. The topography of this area is a deep gorge flowing out to Japan Sea crossing a small mountain range parallel to the coastal line. Wind direction in the gorge is forced towards the parallel to the center line form the general wind. Wind coming into the gorge straightly parallel to the center line from the sea is strengthen by the topography. The wind flowing into the gorge with a little angle from the center line shows large intentity of turbulence. And power spectrum of wind in such a case shows wide energy peak.
