Abstract: For buildings and structures in typhoon regions, they must be designed to withstand typhoon winds. The modeling accuracy of typhoon wind field in the atmospheric boundary layer is therefore very important. The currently-used typhoon wind field models for buildings and structures assume that the pressure of a typhoon does not vary with height above the ground. However, the observations made from recent field measurements do not support this assumption, and this assumption may affect the prediction of typhoon wind field. This paper thus presents a refined typhoon wind field model including variation of pressure with height. The refined typhoon wind field model is then applied to Typhoon York. The wind speed and direction computed from the refined typhoon wind field model are compared with those measured at the Waglan Island and the Di Wang Tower, and those predicted by the Yan Meng model and the Shapiro model. The comparison demonstrates that the refined typhoon wind field model gives more accurate wind speed and direction than other models.
