| 摘 要： | 本文通过对2003年6月22日和7月14日二次暴雨天气过程的多普勒天气雷达资料的分析，发现中低空的水汽辐合、中低空急流和低层垂直风切变引起的辐合是引起强降水的重要原因。表明多普勒天气雷达已成为暴雨短时预报的一种重要工具。

| Abstract: | By using the Doppler weather radar data on June 22 and July 14,2003 in Lianyungaog,two heavy rain cases were contrastively analyzed .The results indicated that mid-and low level vapour convergence,mid-and low level jet and convergence caused by wind's low-level vertical wind shear were accompanied by severe precipitation.It has played an important role in rainstorm nowcasting through analysis of the evolution of Doppler weather radar data. |
