| 摘 要： | 利用伊宁新一代天气雷达资料，结合高空和地面观测资料，分析了2010年7月19日伊犁地区一次局地暴雨天气过程。结果表明：此次强对流天气过程的主要影响系统为500 hPa中亚低槽、200hpa高空急流、低层风速辐合和地面雷暴高压。较强的层结不稳定和低层垂直风切变有利于对流的产生；云图和雷达资料分析表明，此次局地暴雨是由中尺度强对流云团产生，具有典型的对流单体形成、发展成回波短带合并形成带状回波，该带状回波最后演变成一个尺度较大的弓形回波。

| Abstract: | Yining new generation of weather radar data by combining aerial and ground observation data, analyze the July 19,2010YiLi Prefecture time of storm weather process. The results showed that: the strong convective system, the main influence in Central Asia for the 500hpa trough,200hpa upper level jet, low-level wind convergence, and thunderstorms high ground. Strong unstable stratification and low-level vertical wind shear are conducive to the generation of convection; Cloud and radar data analysis indicate that the principal of mesoscale strong convective clouds by rainstorm is produced, the typical convection monomer formation, development into echo short with merger form bands echo, this ribbon echo eventually turned into a measure larger bow echo. |
