【摘要】 利用滤纸法对2006年8月7日～16日祁连山山区地形云降水过程进行雨滴谱取样,获得了260份雨滴谱资料。本文对这些雨滴谱资料进行了分布特征分析,研究了雨滴谱参量的演变特征以及各档雨滴对总数密度、总雨强的贡献。最后拟合分析了雨滴谱Z-I关系。更多还原

【Abstract】 Adopting the filter paper technique, 260 raindrop size-distribution samples were obtained in the precipitation processes from August 7, 2006 to August 16, 2006 in Qilian Mountains region, in western China. In this paper, features of raindrop size distributions and the evolution of micro-structure parameters in mountain area are analyzed. The contribution of the raindrops in various diameter ranges to total number density and rainfall rate are discussed. Moreover, the relation between Z and I in these precipitations is also analyzed.更多还原
