A51D:
Cloud-Scale Processes: Modeling, Observation, and Parameterization for Larger Scale Models II Posters


Session ID#: 8916

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 those processes that occur on space-time scales of individual clouds and smaller, including entrainment/detrainment, turbulent mixing, turbulence, cloud microphysics, cloud-aerosol interactions, boundary layer processes, radiation, and process interactions. These (sub-) cloud processes, whose parameterizations will likely become more important as weather and climate models increase their resolutions, pose particular challenges to modeling studies, observations, as well as parameterization development..This session focuses on modeling (e.g., LES and DNS), observations, and parameterization of such (sub-) cloud processes. Also invited are studies on their interactions and unified treatment of different processes, and integration from observations to theories to models.
