This article mainly carries on the analysis with new weather radar data characteristic in this rainfall process. With the analysis of the reflection factor, the wind profile and the rainfall estimation, we know that the strong wind vertical change and sufficient water vapor condition have the extremely vital role to the development and the maintenance of the convection storm; The new weather radar has the very good instruction function to the weather forecast, specially at the rainfall estimated and in the catastrophe weather forecast and the short-time forecast.

本文主要对这次降水过程中的新一代天气雷达资料特征进行分析，通过对反射率因子、风廓线和降水估测等主要产品的分析，表明较强的风的垂直切变、充足的水汽条件对对流风暴的发展和维持有非常重要的作用；新一代天气雷达对气象预报工作有很好的指导作用，特别在降水估计、灾害性天气预报和短时临近预报中有非常重要的意义。
