Turbulent fluxes of liquid water and buoyancy in partly cloudy layers.

Abstract

A simple convective mass flux model is used to derive expressions for the fluxes of liquid water and buoyancy in partly cloudy turbulent layers. The results differ radically from those suggested in some previous studies. Physical interpretation is given, and examples are presented. Implications for the dynamics of partly cloudy boundary layers are discussed, and the aftermath of cloud- top entrainment instability is analyzed. -Author
