Abstract

Abstract

The uncertainties regarding these hydrological simulation results were further examined by three sets of numerical simulations using different precipitation forcing. It's found that the streamflow simulation using CFSR precipitation forcing exhibited a larger bias than simulations using EAG (East Asia Grid data) precipitation forcing. These results demonstrate the importance of the precipitation forcing chosen for hydrological simulation. Further comparative analysis suggests that the temporal disaggregation method for precipitation forcing preserves the strong diurnal variation, and is therefore also important when conducting hydrological simulations over the Huaihe River basin."
