青岛区域性低涡暴雨的气候特征及预报

Climatic Feature and Analysis of Regional Vortex Heavy Rain over Qingdao Area

对青岛1961～2002年的区域性暴雨个例(3个以上基本测站出现≥50mm降水)进行了分析,指出西南涡、西北涡以及切变涡是造成青岛区域性暴雨最主要的影响系统,其路径不同,所产生暴雨的区域及范围不同,急流的位置及动向和切变线位置是判断暴雨落区的重要因素。

The analysis of regional heavy rain over Qingdao, Shandong Province during 1961—2002 is made.The results show that the south vortex( 25—35°N,100—110°E ),the north vortex (35—40°N,92—105°E )and the shear vortex are the main synoptic systems of regional heavy rain over Qingdao area. The difference of the route and position of vortex will cause the difference of heavy rain area.
