| 摘 要： | 以淮河流域内6部CINRAD雷达基数据资料以及高密度自动雨量站观测资料为源,在应用多种方法进行降水估算和校准,并采用主成分集成方法进行集成应用的基础上,采用"先估算降水再拼图"和"重叠区域选取最大值"的方法来进行整个流域的降水估算结果拼图,从而实现了整个淮河流域的降水估算。从2007年7月初降水过程应用结果来看,经过校准以后估算误差在45%以下,并且能够反映出缺少地面雨量观测站的区域的降水分布,是一种切实可行的淮河流域降水估算的方法。 |

| Abstract: | A method of multi-radar rainfall estimation in Huaihe river is introduced. The method emphasizes the combined use of 6 radars in the area. The processing steps include base-data collection,conversion from radar reflectivity to rainfall rate,rain gauge correction,different rainfall consensus and rainfall mosaics. The step of rainfall mosaics include two sides: rainfall estimation first and then mosaics and maximum selection. During July 2007 the method have been applied in Huaihe river. The application showe... |
