A11N:
US CLIVAR Session on Improved Representation of Physical Processes in Global Models Posters


Session ID#: 9137

Session Description:
The use of detailed observations (e.g., from process studies or intensive field campaigns) to improve representing physical processes in global models is a research priority of US CLIVAR and the broader international community of earth scientists. Improved representation may be achieved via parameterizations or by explicit process representation. 
Pathways to improved model parameterizations are rarely obvious, but key elements include (1) identification of poorly represented physical processes,  (2) developing better understanding of these processes, (3) improving model representation of the process, and (4) evaluation of the effects of these changes on model simulation (e.g., forecast skill, mean state, or changes in fidelity, or other performance metrics).  This session is intended to facilitate progress by fostering dialogue among observationalists, theorists, and model developers. Submissions addressing interactions and exchange between different components of the climate system (e.g. air-sea/ice-ocean/land-atmosphere interactions) are particularly encouraged, as are advances facilitating scale-aware parameterization of subgrid-scale processes.
