Description
Bulk models of the planetary boundary layer (PBL) conventionally rely on diagnostic forms of the turbulence kinetic energy (TKE) equation to determine the entrainment rate. During episodes of rapid deepening or shallowing, the local time rate of change of the vertically integrated TKE becomes significant compared to the difference between gross production and dissipation. A method is presented to determine the entrainment rate in a bulk PBL model...

Description
The concept of "moist available energy," defined by Lorenz is applied to study the potential energy available for cumulus convection in a conditionally unstable atmosphere.
