Impact of human water use on atmospheric extremes in regional climate simulations
The project analyzes existing simulations from European regional climate model downscaling experiments (CORDEX) plus self-provided new climate simulations, incorporating direct water budget modifications at the land surface and in the subsurface, in particular, human water use (including urban) related to groundwater pumping and irrigation. The analyses are accompanied by additional, event-based simulations, applying a (non-identical) twin model setup of varying complexity to further extract long- and short- range relations in space and time between subsurface hydrodynamics and land surface processes with the atmospheric circulation under direct human modification. The project will also analyze the high- resolution Hans-Ertel-Centre reanalysis data (COSMO-REA6). Software and analyses will be made publicly available via Module D in ClimXtreme.
