Impact of Fully Coupled Hydrology-Atmosphere Processes on Atmosphere Conditions: Investigating the Performance of the WRF-Hydro Model in the Three River Source Region on the Tibetan Plateau, China

The newly developed WRF-Hydro model is a fully coupled atmospheric and hydrological processes suitable for studying the intertwined processes. This study utilizes system on Three-River source region. Nash-Sutcliffe efficiency runoff simulation 0.55 compared against observed daily discharge amount of three stations. simulations are better than WRF in terms six ground meteorological elements turbulent heat flux, to data from 14 stations located plateau residential area two flux around lake. Although overestimates soil moisture, higher anomaly correlation coefficient scores (0.955 versus 0.941) were achieved. time series basin average demonstrates that module WRF-hydro functions during unfrozen period. rainfall intensity frequency simulated by closer global precipitation mission (GPM) data, attributed convective available potential energy (CAPE) WRF-Hydro. results emphasized necessity atmospheric-hydrological when investigating land-atmosphere interactions complex topography hydrology
