通过研究GFS未来2~10d分级降雨预报误差的分布规律,分析该信息用于实时调水决策的可行性。对大伙房水库以上流域2001年-2007年汛期GFS降雨预报信息进行分析,结合跨流域调水工程的实际特点进行降雨量级划分,并统计GFS降雨的概率分布,结果表明,该预报信息具有较高准确性,可以结合流域和水库特点用于实时调水决策。
This paper focuses on the GFS forecasted rainfall statistics and analyzes its availability in real-time operation. Based on classification and statistic for GFS forecasted rainfall in 2001-2007, we conclude that GFS forecasted rainfall reaches a high accuracy and can be taken into account in real-time reservoir operation decision making.
