通过建立雨滴分档模式，结合部分观测资料，对中国北方常见的三类典型层状云系：强锋面抬升层状云系、气旋尺度辐合层状云系及弱锋面抬升层状云系的云中水成物总比含水量、降水强度及地面雨滴谱进行了数值模拟，并与观测值进行了比较分析。结果表明，雨滴分档模式较一般使用的单参数 Ｍａｒｓｈａｌｌ － Ｐａｌｍｅｒ（ Ｍ － Ｐ） 分布的参数化模式更能反映雨滴的自然演变特征。 By establishing raindrops subdivision mode and combining with some observation data, three typical stratiform clouds in northern China are strongly stratified uplift stratiform clouds, cyclonic scale convergence stratiform clouds and weak front uplift stratiform clouds The ratio of total hydrate in the clouds to water content, precipitation intensity and ground raindrops were numerically simulated and compared with the observed values. The results show that the raindrop sub - file mode can better reflect the natural evolution of raindrops than the one - parameter Marshall - Palmer (M - P) distribution parameterization model.
