摘要: 运用常规天气图资料,并根据地面自动站和多普勒雷达等资料,综合分析了2007年8月10-12日大连地区暴雨天气过程。结果表明:地面中尺度气旋的生成和发展是产生大暴雨的动力条件,低空急流的建立为暴雨产生提供了大量水汽,稳定的高压坝是暴雨落区在大连出现的必要前提。

Abstract: Based on the synoptic charts data and the ground automatic station data as well as Doppler radar data, the heavy rainfall process happened from 10 to 12 August, 2007 was analyzed in Dalian, Liaoning province. The results indicate that the generation and development of surface mesoscale cyclone is the dynamic conditions causing the heavy rainfall process. The lower level jet provides a lot of water vapor for the development of the heavy rainfall. The steady high pressure barrier is indispensable to make the rainstorm falling areas fall occurrence in Dalian.
