摘　　要：利用 2 0 0 1年 6、7月份的新疆天山山区降水资料 ,对其山区中雨滴谱谱型进行了 M- P分布和Γ分布拟合分析 ,研究了微结构参量演变特征同时分析了各档雨滴对总数密度、总雨强的贡献 ,及大滴的破碎、小滴的形成情况 ,讨论了天山山区的降水与其他地区降水的异同点。The features of raindrop size distributions and evolution of microstructure parameters in mountain area are analyzed and M-P distribution and Г distribution are developed based on the precipitation data observed in Tianshan area from June to July 2001.The contribution of the raindrops in various diameter ranges to total number density and rainfall intensity as well as the formation and brokenness of small raindrops are discussed.Moreover,similarities and differences between precipitation in Tianshan area and that in other region are also studied.
