摘　　要：文章针对庐山气象观测站夏季主要风向与其他高山站存在偏差的现状,对比了汉阳峰和大月山两个新建自动气象站的风向观测数据与庐山气象观测站的风向数据。绘制了庐山气象观测站、大月山站和汉阳峰站的风向频率玫瑰图;并统计出同时段不同台站风向分布差异和各风速下的风向分布差异。最后,结合3站的地理位置,分析了庐山气象观测站夏季主导风向偏差原因。In view of the current situation of the main wind direction of Lushan meteorological observatory station in summer deviated from other high mountain stations,the wind direction observation data of Hanyang Peak and Dayue Mountain are compared with that of Lushan meteorological observation station.The wind direction frequency rose diagrams of Lushan meteorological observatory station,Dayueshan Mountain and Hanyang Peak are drawn.And the wind direction deviation distribution of different stations at the same time and the wind direction distribution difference under each wind speed are counted.Finally,combined with the geographical location of the three stations,the reasons for the main wind direction deviation of the Lushan meteorological observatory station in summer are analyzed.
