利用常规、非常规天气观测资料及MM5数值模拟资料等对2004年11月9～10日山东青岛地区局地大暴雨过程进行了分析,结果表明:(1) 此次暴雨是冷锋前暖区的强降水;(2) 此次暴雨局地性强、突发性强、持续时间短;(3) 西太平洋的水汽是这次暴雨的主要水汽源;(4) 这次强降水发生时大气层结不稳定并不明显,对流层中低层存在对流不稳定,与山东夏季暴雨大气层结强烈不稳定有显著差异;(5) 低层辐合、高层辐散和较强的垂直上升运动是这次暴雨出现的有利动力条件,强降水期间并不必需对流层低层出现辐合;(6) 中低层位涡中心对预报具有很好的指示意义;(7) 青岛特殊的地形和这次降水关系密切.

A local torrential rainfall process during November 9 to 10 2004 is analyzed by using the normal observational data, abnormal observational data and MM5 numerical products etc. The results are shown: (1) The storm rainfall has occurred in warm area which is in front of the cold front. (2) The storm rainfall occurs more suddenly and continues very shortly. (3) The vapor from the West Pacific Ocean is the main vapor source in this storm rainfall process. (4) The atmosphere instability is not obvious when the strong rainfall occurs. Convective instability lies in mid-low level of troposphere. It differs greatly from torrential rainfalls in summer in Shandong province. (5) Convergence in low level, divergence in upper level and strong vertical rising actions are benefit to the torrential rainfall and convergence in low level of the troposphere is not indispensable during the torrential rainfall. (6) The center of potential vorticity in mid-low level is a guider to the torrential rainfall. (7) Terrain effect plays a main pole to the torrential rainfall.
