Abstract: Based on the gale events and lightning data from April to September in Sichuan Province from 2016 to 2021, the gales are classified into thunderstorm gales and ordinary gales, and the spatiotemporal distribution characteristics of the two types of gales and their relationship with terrain factors are analyzed statistically. The results show that the two types of gales in Sichuan are characterized by more on the plateau and less in the basin. The gales are generally dominated by ordinary gales, and thunderstorm gales are relatively high at some stations in the basin. The occurrence frequency of different types of gales in each subarea has daily and monthly changes. For wind speed, the gale in the south of the basin is stronger, followed by the thunderstorm gale in the northeast of the basin and Panzhihua-Xichang region. For wind direction, ordinary gales in the western Sichuan plateau are mainly north wind and southwest wind, while the thunderstorm gales are mainly north wind, and the two types of gales in different regions of Panzhihua-Xichang region and the basin are mainly north wind and northeast wind. The occurrence frequency and wind speed of gales have a certain relationship with different terrain factors, and the general variation trend of different types of gales is similar. The frequency of occurrence increases with the increase of altitude, and increases first and then decreases with the increase of slope, roughness and undulation. The wind speed increases with the increase of altitude, increases first and then decreases with the increase of slope, the smaller the roughness and undulation, the greater the average wind speed and maximum wind speed.
