Abstract:In this study, the free-shear problem, a minimal version of baroclinic, quasi-geostrophic wave-CISK, is analyzed. The basic state consists of a zonal flow, unbounded above and below, with constant vertical shear and Brunt-Vaisala frequency and zero meridional gradient of the potential vorticity; and convective heating is parameterized in terms of the convergence

Abstract:The study considers deep moist convection involving only a liquid-vapor phase change. An alternative form of the classical thermodynamic equation for reversible saturated flow is derived. Four approximate forms of this equation are obtained and their relative errors compared to the full equation are evaluated by using parcel theroy. The best approximation is found to be an adequate representation of the full equation throughout

Abstract:A cumulus cloud's size, shape and internal properties can be predicted, provided that the rate of entrainment is determined by a suitable entrainment parameterization theory. A cumulus cloud model based on such a theory is analogous to mixed-layer models of the planetary boundary layer (PBL) and the upper ocean.

Title:An entraining jet model for cumulo-nimbus updraughts
Publication:Tellus, XIV, 422-434
Abstract:A model of a cumulo-nimbus updraught is presented, based on a steady-state, turbulent condensing plume, entraining environmental air according to the simple law that the inflow velocity at any height is proportional to the upward velocity of the plume.
