Aerosol-Cloud-Drizzle-Turbulence Interactions in Boundary Layer Clouds.

摘要

The long term-goal of this project is to provide an improved description and understanding of the effects of aerosol-cloud interactions and drizzle and entrainment processes in boundary layer clouds for the purpose of developing, improving, and evaluating cloud and boundary layer representations in LES, mesoscale and large-scale forecast models. The scientific objectives are to: (1) document the structure and characteristics of entrainment circulations in marine stratocumulus and fair-weather-cumuli, (2) characterize the vertical distribution of drizzle and how it relates to cloud and mesoscale circulations; (3) investigate the relative role of cloud thickness, cloud turbulence intensity, and aerosols on precipitation production; (4) study the processing of aerosols by cloud processes; and (5) explore mass, moisture, and aerosol transports across interfacial regions at cloud base and at the capping inversion.
