| 摘 要： | 从天气形势、物理量条件、卫星云图等几个方面,对2010年7月20～21日东北出现的一次较大程度的强降水过程进行分析,探讨此次东北暴雨的发生特点及原因。结果表明,副高北上与北方冷涡系统影响,在黑龙江省东、西部造成不同性质的降水。黑龙江省西部在冷涡系统影响下,系统不稳定,造成局地短时强降水;东部在副高外围水汽通道上,在哈尔滨南部地区冷暖空气配合、水汽辐合条件较好,造成暴雨。卫星云图上,西部冷涡中心以阵性对流天气降水为主,东部以连续的暖区降水为主。

| Abstract: | The weather situation,physical conditions,satellites images and so on of a heavy precipitation process happened from July 20 to 21,2010 in Northeast China were analyzed,the occurrence characteristics and causes of this rainstorm weather were studied.Results showed that,the interaction of northward-moving subtropical high with the northern cold vortex system produced different precipitation in East and West Heilongjiang Province.Under the influence of unstable cold vortex system,short-time heavy rainfall oft... |
