A33N:
Upper Tropospheric Clouds and Convection: Processes, Dynamics, and Feedbacks in Weather and Climate I

Submit an Abstract to this Session



Session ID#: 33422

Session Description:
Deep convection, stratiform anvils, and cirrus clouds all play significant roles in controlling the energy budgets and climate feedbacks. With advances in high-resolution modeling and the wealth of observations available, much progress has been made in understanding the nature of upper tropospheric clouds and convection. Recently, GEWEX has formed a working group on Process Evaluation Studies on Upper Tropospheric Clouds and Convection (UTCC PROES) to develop new observation based metrics to advance our understanding on the relation between convection and outflowing anvil properties, in particular their radiative heating, and resulting feedbacks. Motivated by this, we invite presentations on recent findings on UTCC and their dynamics and feedbacks at the process level. Both observational and modeling studies are encouraged to participate. In particular we invite submissions on various aspects of convective systems including links between precipitation, anvil and cirrus cloud dynamics, latent and radiative heating, and upscale feedbacks.
