Linking Clouds, Convection and Circulation: Insights from Models, Theory and Observations
Session ID#: 85470
Session Description:
Atmospheric moist convection plays crucial roles in circulation & climate. The condensation heating drives atmospheric movement ranging from convective to planetary scale. The cloud-radiative effect is crucial for many dynamic systems, such as the Madden-Julian Oscillation, & remains one of the most uncertain climate feedbacks. Wind-evaporation-SST feedback modulates the evolution of many important phenomena, including ENSO, hurricanes, & monsoons. Despite recent progress, fundamental understanding of interactions between moist process & the large-scale circulation & climate at different spatial/temporal scales remains elusive. This session will explore advances in the coupling between moisture, cloud, circulation, & climate. The related topics include, but not limited to, interactions between convection & large-scale circulations, cloud-radiative & other moisture-involved feedbacks & their implications in climate, responses of convective systems & extreme weather to circulation or climate changes, & so on. Observational, modeling (idealized/comprehensive), & theoretical studies are all welcome.
