H33G:
Teleconnections in Hydrological Systems at Decadal Timescales: Challenges for Hydrological Modeling and Projection Uncertainties Posters


Session ID#: 8481

Session Description:
Hydrological systems are very sensitive to changes in global and regional climate. Recent and future climate change is expected to increase potential evapotranspiration and possible complex changes in rainfall variability and event distributions which can impact on soil moisture, streamflow, groundwater recharge, magnitude/frequency of fluvial floods and droughts. High-resolution simulations from global to regional climate models can be used to force hydrological models and provide regional projections of hydrological changes at catchment scales.

 Regional climate models, however, have serious problems in reproducing teleconnections between global climate oscillations and regional hydrosystems. This can result from lateral boundary forcing or by uncertainties related to internal climate variability, especially at the decadal timescale. This session therefore solicits abstracts on research providing new approaches or insights into understanding decadal teleconnections between regional hydrosystems and global/internal climate modes of variability, which reduce uncertainties in modeling hydrological changes.
