摘　　要：文章通过分析2021-08-19的1次持续时间长、雨量级小的层状云降水过程,以微雨雷达底层数据作为参考进行系统偏差订正,随后运用逐库法对毫米波云雷达回波进行订正,将订正后的结果与微雨雷达整层回波进行对比,验证订正效果,可为提高天气预报准确度及设计人工影响天气作业方案提供有效的数据支撑。By analyzing one stratiform cloud rainfall process featuring long duration and small rainfall grade happened on August 19,2021 and taking the underlying data of light drizzle radar as reference,this paper makes a correction for system deviation and then corrects the echo of millimeter wave cloud radar and makes the corrected results compared with whole layer echo of micro-rain radar,in order to verify the effect of correction and provide effective data support for the improvement of accuracy of weather report and design of operation scheme for artificial weather influence.
