Regional Climate: Modeling, Analysis, and Impacts

Session ID#: 157843

Session Description:
This session focuses on the state of the art in modeling and analysis of regional climate and regional climate impacts on subseasonal-to-multidecadal-to-centennial timescales. Contributions are solicited on coordinated modeling experiments such as CORDEX; novel approaches for model evaluation and analysis, especially process-oriented analysis of climate extremes in observations and simulations; new developments such as coupled earth system modeling at regional scales and convection permitting simulations; ensemble methods and uncertainty analyses; and assessing the added value of regional modeling. Results from the use of regional models for process understanding, downscaling of IPCC climate change scenarios, and modeling and analysis of climate impacts are also encouraged.
