| 摘 要： | 将“713”测雨雷达和GMS卫星云图资料引入PSU／NCAR中尺度模型，以改变初始湿度场，对两个不同类型的江淮暴雨过程进行了数值模拟敏感试验，并与控制试验作了比较分析。结果表明：加入雷达和卫星资料，能通过水汽和辐合上升运动的调整有效降水过程，引入雷达和（或）卫星资料所产生的影响有所不同。

| Abstract: | The sensitivity experiments (STE) of numerical simulation,in which the radar and/or satellite data were incorporated into the PSU/NCAR mesoscale model to modify the initial moisture field,for two kinds of heavy rainfall processes over the Changjiang Huaihe river basin have been performed and compared with the control experiment (CTE) without using radar and satellite data.The results show that there is a great improvement in the simulation for 24 hour precipitation forecasts through the adjustment of water vapour and ascending motion by incorporating of radar and satellite data into the mesoscale model.The area and amount of rainfall obtained by STE are more in agreement with the obtained fact than those from CTE.The impact of radar and/or satellite data on simulation result is different for different types of rainfall process. |
