摘要
鉴于大部分气象系统对外发布的降雨预报信息均为降雨预报图的形式而不能直接用于水库调度,设计了一种GFS降雨预报图数值化处理算法,可计算出降雨预报图中任意像素点的降雨数值预报信息,然后利用计算出的GFS降雨数值预报信息与洪水预报模型耦合来进行洪水预报,并以桓仁水库2010年的一场洪水为例进行了验证。结果表明,利用该算法计算出的降雨数值预报信息可应用于洪水预报,具有较好的应用前景。
Most rainfall forecast information released by the meteorological system is in the form of rainfall map, which can not be used to reservoir operation directly. So, this paper proposes an algorithm for numerical processing of GFS rainfall map, which can calculate the rainfall in any pixel of rainfall forecast map. The flood forecasting is carried out by integrating with the GFS rainfall forecast information and flood forecast model. Finally, a flood process of Huanren reservoir in 2010 is used to verify the proposed method. The results show that the new method can be applied to flood forecasting with good applicable prospects.
