【摘要】 利用中尺度数值模式(MM5 v3.5)对2003年4月17~18日山东春季大暴雨过程进行了数值模拟。在较为准确的模拟基础上,分析了该暴雨过程的形势演变和水汽条件,计算了暴雨发生过程中山东省范围水汽输送、水汽收支和空中各相态水物质的量值大小及其转化关系。初步揭示了具体降水天气系统中的水循环过程和云水资源转化特征。更多还原

【Abstract】 By using non-hydrostatic model MM5 v3.5,a heavy rain occurred on 17 April 2003 in Shandong province was investigated.The evolutionary process,development mechanism and the water vapor condition of this case were analyzed.The amount of import,export and income of the water vapor in Shandong region were calculated,the content of various state of water and the transform relations among them in cloud were analyzed.The results are helpful for explaining the characteristics of the water vapor cycle in a rainfall process.更多还原
