Cumulus dynamics from reduced-order perspectives
Session ID#: 79231
Session Description:
The representation of cumulus convection in climate models usually relies on reduced-order cloud models (i.e. parameterizations). The details of how these models are formulated can have dramatic impacts on the representation of weather and climate phenomena. Thus, the assumptions used to simplify the underlying processes deserve careful scrutiny. This session aims to discuss recent advances in formulating and understanding reduced-order representations of cumulus convection, either from a theoretical, observational, or numerical perspective.
