A31E:
Processes of (Sub) Cloud Scales: Modeling, Observation, and Parameterization for Larger-Scale Models IV Posters

Submit an Abstract to this Session



Session ID#: 25064

Session Description:
Clouds continue to defy our understanding and are major sources of uncertainty in weather forecasting and climate projection. Key to addressing such outstanding cloud challenges are the processes that occur on space-time scales at individual clouds or smaller, including entrainment/detrainment, turbulent mixing, turbulence, cloud microphysics, boundary layer processes, radiation, and process interactions. These (sub) cloud processes pose particular challenges to modeling studies, observations, as well as parameterization development. The parameterizations will likely become more important as weather and climate models increase their resolutions. This session focuses on modeling (e.g., CRM, LES and DNS), observation, and parameterization of such (sub) cloud processes. Also invited are studies on unified treatment of different processes, and integration from observations to theories to models.
