摘　　要：文章利用5个自动气象站的小时雨量数据与吴忠新一代天气雷达对应时段的反射率数据以及OHP产品数据,形成雷达估测小时雨量-自动站雨量数据对,并对所得数据样本进行了对比分析。同时利用雷达反射率获取自动站雨量数据,选择最优化方法得到Z-I关系中的A、b系数,由评估结果可知能在一定程度上提升吴忠雷达的定量估测降水能力。By using the hourly rainfall data of five automatic weather stations and the reflectivity data of Wuzhong new generation weather radar and the data of OHP products,the pairs of radar estimated hourly rainfall data are formed and the data samples are compared and analyzed.At the same time,the radar reflectivity is used to obtain the rainfall data of the automatic station and the coefficient of A and b in Z-I relation are obtained by the optimization method.According to the evaluation results,it can improve capability of quantitative precipitation estimation to some extent in Wuzhong radar.
