Cloud-Aerosol-Precipitation Interactions and Their Parameterizations in the Context of Weather and Climate

Session ID#: 77838

Session Description:
Over the last decades, studies of cloud-aerosol-precipitation interactions (CAPI) have evolved. These studies have started by focusing on aerosol-induced microphysical changes in cloud-particle sizes, and moved to feedbacks between aerosol, microphysics, thermodynamics, radiation, and dynamics. CAPI studies have also moved from CAPI in a small cloud system or a single cloud to a mesoscale or a larger-scale cloud system for a better understanding of CAPI in the context of weather and climate. With this evolution, the parameterization of CAPI in weather and climate models has evolved, although lack of the understanding of CAPI has slowed down the development of the CAPI parameterization. Hence, this session invites all observational, experimental and modeling studies of CAPI that enhance the understanding of CAPI, and adopt the traditional microphysical approach and/or the recent approach including those feedbacks. Studies associated with the development of the CAPI parameterization and its application to models are also welcome.
