Changes of Water Vapor Budget over East Asia in Response to 4xCO2 Concentration Forcing
Water resources are essential for the economic development and social security in East Asia, especially under global warming. Based on newly released CMIP6 149-year simulation data from a pre-industrial control experiment (piControl) and a forced experiment on the abrupt quadrupling of CO2 concentra...

Water resources are essential for the economic development and social security in East Asia, especially under global warming.

Change of precipitation (P) demonstrates a spatial pattern of “Southern Flood and Northern Drought” (SFND) in eastern China, which can also be seen in the change of evaporation (E), though at a much smaller amplitude.
