【摘要】 2016年6月23下午,江苏阜宁发生罕见的冰雹、龙卷特大自然灾害,造成了巨大的经济损失和人员伤亡。本文利用盐城SA新一代雷达资料分析此次过程的风暴特征,并与2018年5月12日邢台的冰雹大风天气过程进行简单对比。结果表明:阜宁龙卷发生于200 hPa高空急流出口区右侧,为500 hPa槽前强盛的西南暖湿气流控制,中层存在干冷空气,低层有明显的切变,环境场具有高对流有效位能（CAPE）、较强的垂直风切变（WSR）和较低的抬升凝结高度（LCL）;阜宁龙卷产生前,风暴的最大反射率因子强度(Z_max)、强回波中心高度（HT）、回波顶高（TOP）持续增加,垂直累积液态含水量（VIL）激增,龙卷发生前2个体扫,HT和VIL出现骤降;阜宁龙卷过程出现明显的三体散射现象,对大冰雹预警具有指示意义;阜宁龙卷风暴具有经典超级单体的钩状回波和强中气旋特征,并伴有TVS,是一例由庞大的超级单体风暴形成龙卷的特大灾害,相比于邢台冰雹大风过程,其旺盛阶段的风暴参数明显大于后者。更多还原

【Abstract】 The great natural disaster of a rare hail, tornado occurred in Funing of Jiangsu Province on 23 June 2016. It caused huge economic losses and casualties. Based on the observed data from Doppler radar（SA） in Yancheng, this process was analyzed, and then compared with the strong convective weather in Xingtai on 12 May 2018.The results show that the Funing tornado occurred at the right side of the 200 hPa high-altitude jet stream exit. It was controlled by the strong southwest warm and wet airflow at the front of the 500 hPa trough. There were dry cold air in the middle layer and obvious shear in lower layer. Its environmental field had strong convective available potential energy（CAPE）, vertical wind shear（WSR） and lower height of uplift condensation（LCL）. Before the Funing tornado, the maximum reflectivity factor(Z_max), strong echo center height（HT）, echo top height（TOP） continued to increase, the vertically integrated liquid water content（VIL） surged. In the 2 volume sweeps before the tornado, HT and VIL felled sharply. There was an obvious three-body scattering phenomenon in Funing tornado, which was an indication for early warning of hail. Funing tornado storm had the characteristics of hook echo and strong mesocyclone of classic super cell, accompanied by TVS. It was a huge disaster caused by huge super cell storm. Compared with the hail wind process in Xingtai, the storm parameters of Funing tornado at its vigorous stage were obviously larger than those of the latter.更多还原
