摘要
2009年山西省引进了中国气象科学研究院人影中心的MM5云参数化模式并初步实现了业务化运行，生成的云物理量产品主要有温度场、高度场、水汽场和各种云中水成物粒子的比含水量以及水平和垂直分布状况。该模式的初始场为T213预报场资料，采用10km的分辨率。本文选择了2010年4月19日-21日山西省一次春季层状云降水过程作为分析个例，应用雷达、NCEP水汽场再分析资料，并重点采用该MM5中尺度云参数化模式输出的数据，对山西省春季层状云的宏微观结构特别是云系垂直方向上的微物理结构进行了详细的分析，在此基础上总结出本次春季层状云降水的宏微观结构特征。
The MM5 cloud parameterized model of Chinese Academy of Meteorological Sciences was introduced to Shanxi province in 2009. It runs regularly. Its results of cloud physical include temperature field, height field, vapor field and the horizontal and vertical distribution of the particles of hydrometeor in different cloud. Its initial field is the data of T213 forecast fields and its resolution is 10KM. The spring April 19 to 21, 2010 was taken as an example. The spring stratiform clou precipita as macro tion process of stratiform clouds in and micro structure were analyzed based on radar data, the vapor field reanalysis data of NCEP and the output data of MM5 cloud parameterized model The macro and micro structure of the spring stratiform clouds were got on this basis.
