| Abstract: | 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 . |
