Boundary Layer Clouds

Clouds can form at the top of mixed layers, and at the bottom of stable boundary layers. The amount and distribution of short and long-wave radiative flux divergence in the boundary layer are altered by clouds, and these effects are emerging as important aspects of the climate-change problem. In addition, the radiative effects combine with latent heating to modulate BL dynamics, turbulence generation, and evolution. This chapter provides a brief review of cloud thermodynamics, radiative processes, the role of entrainment, and descriptions of fogs, cumulus and stratocumulus clouds.
