摘要
本文利用主特征提取法、统计权重法、综合概率法等方法 ,对Z R关系法、平均校准法、最优插值法、卡尔曼滤波和最优插值联合校准法、卡尔曼滤波校准法降水定量估测模式输出结果进行集成分析。初步结果表明 :统计权重法的集成结果与实况地面雨量计测得雨强值吻合较好 ,可以在估测区域降水量集成分析中进行业务试用。
In term of the methods of K L transform,statistical weight and probability mean we consensus the rainfall estimate values from the models of Z R ,Kalman filter,optimum interpolation,Kalman filter and optimum interpolationi and average calibration.Evidences suggest that the consensus results are close to the measurements from the automatic rain gauges in site and the statistical weight methods can be served as the operational methods to estimate the region rainfall.
