摘　　要：使用常规观测资料、台风路径资料、庐山地形和观测站雨量资料,采用统计方法和对比分析,对庐山夏季强降水的特征及其与台风活动的关系进行分析,结果表明:①每年7—9月是庐山的盛夏季节,也是台风活动高发期,其降水特征表现为阵性明显、雨强较大。②庐山夏季强降水的影响系统主要为台风系统,其次是西风带系统、副高边缘系统和东风波系统。③影响庐山的台风路径主要是中路且可以细分为中路Ⅰ型和中路Ⅱ型。在对庐山无影响的中路台风个例分析中,登陆后台风中心位置没有越过北纬25°N线是关键指标。④庐山地形对台风降水的影响十分明显,受庐山地形影响产生的降水往往是山下站点的几倍。Using conventional weather data,the typhoon path data,Lushan topography and rainfall data from observation stations,the basic characteristics of Lushan summer severe precipitation and the relations between Lushan summer severe precipitation and typhoon activities were analyzed with statistical and comparative analysis methods.The results show the following：（1） Midsummer season of the Lushan Mountain is from July to September.This is also a period of high incidence season of typhoon activity.The precipitation characteristics are obvious shower with greater rainfall intensity.（2） Weather systems of Lushan summer precipitation are mainly typhoon system,followed by the westerly wind belt system,the limbic system of the subtropical high as well as easterly wave system.（3） Typhoon paths impacted on Lushan is mainly Middle Road,and it is subdivided into RoadⅠtype and Road Ⅱtype.In the cases of typhoon in Middle Road without impact on Lushan,the landed center site not crossed latitude 25°N is a key indicator.（4） The impacts of Lushan terrain on typhoon precipitation are evident.The precipitation influenced by the topography is often several times than that on the foot.
