It is well known that some topography causes a wind increase and unexpected gust factors. To examine the characteristics of the gust factors by every wind direction throughout Kyushu area, the authors have organized a database of strong wind data classified into non-typhoon and typhoon. The authors have confirmed the different tendencies of gust factors according to the wind direction at several terrains using the database. The database shows that the gust factors of winds by typhoons are generally higher than by non-typhoons even when the wind speed is high. And the authors have found that the gust factor at Imajuku, the western part of Fukuoka City, is much higher in southern wind direction. Such a database on the gust factors is useful to estimate a peak gust in strong winds.
