利用青海西宁多普勒天气雷达和常规观测资料,对2010年7月6日发生在青海高原东部海晏县境内的一次短时强对流天气进行了分析。结果表明：哈密附近沿西北气流快速东移南下的短波槽是这次海晏强对流天气的主要影响系统,在雷达回波图上表现为有中气旋相伴随的强降水类型的超级单体特征。最大液态含水量第一次爆发式增长随即降低对应强降水开始,第二次降低对应冰雹降落,风廓线图上40 kft以下双层连续无资料区的逐渐破坏直到完全建立对应降水从开始到减弱的过程。强回波区〉50 dBZ、在降水回波中包裹着中气旋以及＂弓＂型回波后侧的V字形槽口是此次过程中强降水超级单体区别于其它类型超级单体的主要特征。〉50 dBZ回波高度伸展到-10℃层高度以上而没有到达-20℃高度,是这次过程中无大冰雹降落的主要原因。

Based on conventional sounding data and Doppler radar information of Xi＇ning station in Qinghai Plateau,a short-time strong convective weather process occurred in Haiyan on July 6,2010 was analyzed.The result shows that the short wave trough along the north-west stream in Hami area moving southeastward was the main influencing system,the heavy rainfall supercell accompanied with mesocyclone is the dominating characteristic on radar echoes chart,the first time when the integrated liquid water content increasing explosively and then decreasing immediately was corresponding to the starting of strong rainfall,and the second decrease of VIL was corresponding to hail falling.The course of successive double-layers with no data below 40 kft from destructing gradually to buiding-up completely on wind profile chart was just corresponding to the whole rainfall process.The main character of the rainfall suppercell during this weather process was that the reflectivity factor was more than 50 dBZ,and precipitation echo enwrapped the middle cyclone,as well as the V-shaped notch was behind the bow echo,which were different from other type suppercells.The height of radar echoes more than 50 dBZ ranged from-10 ℃ and-20 ℃ level,which resulted in no large hail falling during this weather progress.
