A34F:
Insights on Clouds, Convection, and Climate Sensitivity from Idealized Modeling Studies II


Submit an Abstract to this Session


Session ID#: 58382

Session Description:
The response of clouds to warming is the largest source of uncertainty in estimates of climate sensitivity and depends on convective processes which are largely parameterized in climate models. Convective self-aggregation, in which convection spontaneously organizes without external drivers, has potentially large but unknown implications for climate sensitivity. Radiative-convective equilibrium (RCE) is one idealized framework that has been used to phrase important questions about the coupling of clouds and convection to the climate system, and has the advantage of being accessible by a wide variety of models, including both those with explicit and parameterized convection. Contributions are solicited from studies using models, ranging from cloud-resolving to climate scales, that address changes in clouds and convection with warming, cloud feedbacks and climate sensitivity, and self-aggregation and its role in climate. Submissions of results from models configured in RCE, including but not limited to the recently organized RCEMIP intercomparison, are particularly encouraged.
