摘要
在统计美国全球预报系统（GFS）桓仁流域的数值降雨预报与实际降雨结果的基础上，考虑不同预见期加权，分析了预见期为1～3d的降雨预报的可利用性．分析结果表明，考虑预见期加权的GFS降雨预报较不考虑预见期加权的预报可利用性明显提高．该方法对水库调度运行有重要的实际指导意义．
Based on the statistical analysis of global forecast system（GFS） forecasting rainfall and actual rainfall in Huanren basin, considering different forecast horizon weights, the availability of GFS rainfall forecast in a period of 1-3 days is analyzed. The computing results show that the availability of GFS rainfall forecast considering forecast horizon weights is obviously higher than that without considering forecast horizon weights. The proposed method has a great significance for reservoir operation.
