Abstract

<p>For reasonable designs of transmission towers, it is effective to consider the directional characteristics of wind loads. This paper deals with extreme wind speeds on each directional sector for whole territory of Japan, especially focusing on the contribution of typhoons. The statistical analyses of annual maximum wind speeds on ground observations reveals the directional characteristics of extreme winds and positional relationship between storm centers and observation points. Maximum (1961-2015) and annual maximum wind speeds in west and northwest wind sectors tend to be recorded when typhoon had not been approaching, despite the maximum wind speeds for other wind sectors are mainly caused by typhoons. Over Japan, west and northwest wind fields are out of stronger wind area in the right semi-circle of typhoon. This trend is explained by the typhoon wind profile and traveling velocity.</p>
