| 摘 要： | 2010年8月11至13日,陇南市连续发生强降雨,引发暴洪、泥石流和滑坡等地质灾害.本文讨论暴雨的天气实况、环流背景和物理特征,从云图和降雨特征分析降雨机理.研究发现,副高边缘低槽东移形成低涡,在涡旋过程中单点降落,是形成暴雨的根本原因;又因单点的强度太大,短时形成灾害.

| Abstract: | From August 11 th to 13 th of 2001,continuous heavy rains occurred in Longnan,triggering flash floods,debris flows,landslides and other geological disasters.This article discusses the weather condition,atmospheric circulation background and their physical characteristics.The rainfall mechanism is also analyzed in terms of nephograms and precipitation characteristics.The low groove at the edge of the subtropical high pressure developed into low vortexes as it moved eastward,because of which storms formed;the vortexes and storms were so strong at certain points as to cause disasters. |
