| 摘 要： | 对2010年7月16日和2011年7月15日两次冷涡位置相似,造成的天气不尽相同的冷涡天气过程,从环流背景、物理量场、卫星云图进行了分析,结果表明：高空冷涡和低层中尺度切变是主要影响系统;由于中低层温度场配置不同、低层切变位置不同、导致天气不同;强对流天气与SI指数的负值区、K指数大值区及CAPE的高值区有较好的对应关系;卫星云图上是一个边缘整齐光滑的对流积雨云团。

| Abstract: | The two cold vortex position were similar between on July 16,2010 and July 15,2011,but they caused different weather during the cold vortex.The circulation background,physical quantity,satellite image were analyzed,the results showed that: upper cold vortex and low-level mesoscale shear are the main influence systems.Because the lower temperature configuration,the low-level shear in different positions,resulting to the weather are different;severe convective weather area with negative SI index,K index value... |
