Dynamics and Impacts of Hydrologic Intensification
Session ID#: 248674
Session Description:
Hydrologic intensification is a unique facet of the climate response to greenhouse forcing, characterized by jointly amplified wet and dry extremes and coupled changes in sub-annual precipitation and evaporation. It has broad implications for ecosystems and society, but its evolution and impacts are very uncertain. This session invites research across the atmospheric, hydrologic, and terrestrial sciences to understand the diverse drivers and manifestations of hydrologic intensification and its impacts on terrestrial systems. We welcome research on the land and atmospheric dynamics of water-cycle amplification and links to climate feedbacks and eco-hydrologic change. We also invite submissions that focus on the impacts of this intensification on hydrologic stocks and fluxes (e.g., evapotranspiration, runoff, soil moisture, groundwater), vegetation, agriculture, the carbon cycle, and wet and dry extremes. Theoretical, observational, and modeling approaches are equally welcome.
