| 摘 要： | 利用常规观测资料、卫星云图、自动站气象观测资料和多普勒雷达等资料,对2011年6月16日玉林市南部一次中尺度强降水过程进行天气动力学和中尺度分析,结果表明:这次暴雨是在有利的大尺度环流下产生,通过中尺度系统激发而产生的。高空低槽和低空切变辐合是强降水产生的前提条件,中尺度对流云团强烈发展是强降水产生直接原因;分析红外云图的TBB、多普勒雷达反射率和基本速度、地形条件等方面都很好地阐述了本次强降水的暴雨中心。

| Abstract: | Basing on the conventional observation data,satellite cloud images,AWS data and Doppler radar echo data of June 16,2011 in Yulin City,the mesoscale heavy rainfall weather process in Southern Yulin was analyzed.The results show that:the rain occurs under the favorable large scale circulation,induced by the mesoscale systems.In background of upper trough and low-level shear convergence,the mesoscale convective cloud cluster strongly development is direct causes of the strong precipitation.The TBB of infrared satellite cloud,Doppler radar reflectivity and basic speed,and terrain effect have good indication of the rainstorm center. |
