摘　　要：为延长水文预报有效预见期,提高预报精度,采用WRF模型降雨预报作为输入,建立针对长江上游的WRF定量降雨预报模型,利用2014年WRF模型对长江上游的预报结果,采用水文气象耦合的方式,研究输入资料在空间尺度变化的情况下对水文预报的影响。Hydrological and meteorological coupling prediction is an important mean to prolong the effective forecast pe-riod and improve the accuracy .A quantitative precipitation forecasting model is developed for the upper Yangtze River Basin , in which the WRF model is taken as the input and the hydrological and meteorological coupling scheme is adopt -ed.Based on the forecasting results of the WRF model for the upper Yangtze River Basin in 2014 , effects of the spatial scale change of the input data on the hydrological forecast are investigated .
