Seasonal simulations of the planetary boundary layer and boundary- layer stratocumulus clouds with a general circulation model.

Abstract

The UCLA general circulation model (GCM) has been used to simulate the seasonally varying planetary boundary layer (PBL), as well as boundary-layer stratus and stratocumulus clouds. The PBL depth is a prognostic variable of the GCM, incorporated through the use of a vertical coordinate system in which the PBL is identified with the lowest model layer. -from Authors
