西南地区东部、华南等地将有小到中雨或雨夹雪；

The eastern part of Southwest China and South China will suffer small to moderate rain or sleet.

结果表明，从相对误差来看，双线偏振雷达使普通雷达的小雨高估、大雨低估的测量误差趋势减弱，它对小到中雨的测量结果优于普通雷达。

The result indicates that the underestimation of the rainfall rate during heavy rain and the overestimation during light rain become small by ZDR method.
