Abstract: Based on the data of 13 meteorological observation stations in Xichang, the distribution characteristics of force seven and above wind in Xichang are analyzed, and the following conclusions are drawn: (1) Force 7 and above winds in Xichang occur in each month, with large seasonal differences. (2) The number of days and the maximum wind speed are characterized by more (large) in valley plains in the middle, less (small) in mountains on both sides, decreasing (small) from north to south. (3) The daily extreme wind direction shows symmetry and orientate. The south-north symmetry is strong, and the east-west symmetry is weak. The locking directions corresponding to different station locations are also different, and the single station locking direction has strong continuity.
