Meteorological data during typhoons, measured at 46 JMA meteorological observatories in Japan from 1975 to 1997, are analyzed from the viewpoint of building damage. The number of typhoons used for the present analysis ranges from 29 at Sapporo to 110 at Okinawa. Special attention is paid to the gust factor and the intensity and amount of precipitation at and after the occurrence of the maximum peak gust. Based on the results, a simple model of the gust factor is provided, in which the effect of terrain roughness is considered. Furthermore a stochastic model is proposed for the amount of precipitation as a function of the shortest distance between the typhoon center and the observation site. These models can be incorporated into a prediction model of typhoon-induced building damage, which the authors are now developing.
