Another look at the scale analysis for deep moist convection.

Abstract

In this note, a more rational approach is given to specify the parameters G and B in the scale analysis of Lipps and Hemler. The thermodynamic equation is written in a different form so that a closed expression for B can be derived. The present values of G and B are very similar to those in the previous scale analysis. A new result is that the time scale tau is expressed in terms of the moist convective instability rather than the inverse of the Brunt- Vaisala frequency. -from Authors
