A43J:
Process-Oriented Evaluation of Climate Model Physics Using Observations and High-Resolution Models I


Session ID#: 10940

Session Description:
Current uncertainty in climate projection is caused in large part by uncertainty in representation of physical processes in climate models. To mitigate this uncertainty for more reliable climate projections, it is critical to appropriately evaluate and constrain such uncertainties at a fundamental process level. In this session, we solicit presentations that contribute to the evaluation and improvement of global climate models with a particular emphasis on physical processes that have typically been represented by parameterizations. Specific focus of this session includes innovative use of available observations (satellite, aircraft or ground-based) or high resolution modeling to diagnose key aspects of physical processes. Presentations of new validation metrics for evaluating model physics and their applications to constrain key uncertainties in formulation of parameterization are encouraged. Presentations on how the process-based constraint on model physics impacts the overall model performance of climate simulation are also welcomed.
