摘要

The primary objectives of the research are to numerically simulate stratus,stratocumulus, and cumulus clouds in the marine boundary layer. This will include the formation, evolution, and dissolution of the clouds and the area covered by the cloud fields. If a large enough domain can be covered, then the change from one type of cloud to another would be investigated. Also the change from open cell to closed cell type convection and the formation of cloud streets could be investigated. Another objective is to increase our understanding of conditions in the marine boundary layer. What determines the vertical profiles of humidity, temperature, and cloud characteristics in space and time. What causes the changing depth of the boundary layer. What are its interaction with the clouds in and out of the boundary layer. A third objective is to compare various numerical models among themselves and with observations.
