摘要
利用多普勒天气雷达资料,结合宁夏精细化预报产品,对2003年9月5日的一场降水过程进行了雷达气象学和中小尺度天气学分析,得到了一些初步结果.分析表明:多普勒雷达降水回波强度变化、降水回波总面积、强回波面积与降水过程相吻合.多普勒速度场、回波顶高、垂直累积液态含水量、对应的上升气流以及温度平流对这次降水具有预报指示意义.
Radar and mesoscale meteorology analysis was conducted on a rainfall taken place on September 5 2003 by using Doppler radar data and mesoscale numerical weather forecast model products. The results suggested that the change of rainfall echo intensity, echo area of intensive precipitation and total area of echo were corresponding to the change of precipitation. The vortex in Doppler velocity field, echo tops, vertical integrated liquid, lift stream and cold advection are significant in this rainfall case.
