| 摘 要： | 讨论变分校准法用于雷达－雨量计系统联合探测降水。由雷达反射率因子Ｚ和地面降水强度Ｉ实时地获得最优Ｚ－Ｉ关系，在求解欧拉方程时采用多重网格法，不仅可提高计算结果的精度，还可大大提高计算速度。

| Abstract: | This paper concerns a scheme for a radar rainguage system in measuring rainfall treated by variational calibration. The optimal Z I relation is established with real time data and the multigrid method is used in solving the Euler equation. These considerations can improve data accuracy in a target region and save time as well. |
