Application of Fine-Mesh Grid Numerical Model LSP Products in Hydrometeorological Service

In this article, we establish a statistical forecast model by using the T639, GER and JMA predicted rainfall products at grids as meteorological factors and the upstream hydrological precipitation data in Hanjiang River basin as the predictor, The test results show that the proposed method may reflect the distribution of the precipitation in the basin objectively, particularly for heavy rains. It may provide a scientific reference for fl ood control and drought relief at Danjiangkou reservoir storage scheduling, and the technique may be beneficial for similar issues.
