摘 要: 以综合利用水库群工程为背景,分析了美国全球预报系统(GFS)发布的降雨预报信息利用方式及其可利用性,进而对大伙房流域2001-2007年17场洪水后未来10d的预报降雨量和实际降雨量进行分析比较。结果表明,雨后大伙房水库流域GFS降雨预报信息精度更高,结合短期降雨可用于水库群调度决策。 Based on the background of comprehensive utilization reservoir group project, the paper analyzes the grading utilization modes and availability of rainfall forecast information which provided by the Global Forecast System(GFS). Comparing and analyzing next ten days forecasting precipitation and actual precipitation after 17 flood from 2001 to 2007 in Dahuofang watershed, the result shows that GFS rainfall forecast information after heavy rain has high accuracy in Dahuofang reservoir watershed, and it can be used for the actual decision making of inter-basin water transfer project.
