Simulation of future climate variations using global circulation model and downscaling model

Precipitation is the main cause of variability in the water balance over space and time on the earth surface, and changes in precipitation have important implications for hydrology and water resources. Precipitation varies in space and time as result of the general circulation patterns of atmospheri...
