Evaluation of the Precision of Doppler Radar Rainfall Estimation Using Different Algorithms in the Yishu River Watershed
沂沭河流域不同多普勒雷达降水量估算方法的效果评估

By means of the Doppler radar measurements and automatic precipitation station data collected during nine precipitation processes in the Yishu River watershed in 2005 and 2006, the improved window probability matching method (WPMM), improved genetic algorithm (IGA) and the optimization method (OM) are employed to determine the relationship between radar echo intensity (Z) and precipitation intensity (R). The evaluation of the Z-R relation from WPMM, IGA and OM is analyzed and compared with that of the empir...
