| 摘 要： | 利用单多普勒天气雷达的反射率因子、径向速度数据和双多普勒雷达反演的三维风场,分析了一次强烈雹暴的产生、发展和维持机制.主要结果为:该雹暴是产生于中等偏上垂直风切变和较大的对流有效位能条件下的右移风暴,它在旧无序多单体风暴的右侧产生.旧的多单体风暴和雹暴初始阶段主要雷达回波区域负的径向速度(向着雷达的速度)占主导地位,随...

| Abstract: | Using the data of radar reflectivity,radial velocity from a single Doppler radar and three-dimensional wind data retrieved from dual-Doppler radar,the formation,development,and maintenance mechanisms of a severe hailstorm were analyzed.The results showed that the hailstorm formed on the right side of an old disordered multi-cell storm and moved rightward,with moderate or higher vertical wind shear and large convective available potential energy(CAPE).In the old disordered multi-cell storm and at the initial... |
