Abstract

Abstract

The southeastern coastal region of China faces the threat of typhoons from the Northwest Pacific every year， and coastal transmission lines may suffer severe damage. However， due to insufficient measured data， it is often impossible to accurately estimate the extreme wind speed in typhoon climates. A full-path simulation method based on random forest was used to simulate typhoons in the Northwest Pacific， and the YM wind field model was used to carry out typhoon wind field simulations. The extreme wind speeds of a transmission line site under 50-year and 100-year return periods were obtained as 33.7 m/s and 35.8 m/s， respectively. The distribution maps of the extreme wind speeds in Wenzhou and Yueqing were plotted， which suggested that typhoon wind speeds in inland areas showed a decreasing trend. The impacts of microtopography on the extreme wind speeds of typhoons were further analyzed. The computational fluid dynamics （CFD） method was used to calculated the acceleration ratio of the wind speed under real topography to subsequently correct the extreme wind speed distribution map. The corrected results revealed a significant increase in the extreme wind speed， indicating the microtopographic region had a notable amplifying effect on the typhoon design wind speed.
