| 摘 要： | 利用M icaps实时资料、高分辨率T639零场资料、NCEP再分析资料、雷达资料,对2009年4月18日夜间～21日白天辽宁省降水系统的宏观特点及物理量场的结构特征进行了分析。结果表明,中、低纬高空槽的合并加强与地面江淮气旋北上是此次降水过程的主要影响系统,东部高压的阻挡及低空急流对水汽的不断输送是造成近3 d多持续降水的主要降水机制;500 hPa以下高度为水汽辐合区,同时又是上升运动区,700 hPa是急流区,也是水汽输送最强区;雷达回波的零度层亮带与高度场、温度场配置相互吻合。

| Abstract: | Macroscopic characteristics of precipitation systems and physical elements of the structural characteristics during the April 18th night to 21st day of 2009 in Liaoning were analyzed using Micaps real-time data,high resolution initial data of T639 zero field data,NCEP reanalysis data and Radar data.The results showed that the main impact system of the precipitation is the upper trough of middle and lower latitudes merger strengthened and with the ground JiangHuai cyclone north,east high pressure blocking an... |
