Penetrative Convective Instabilities in Parallel Flows.
Abstract
An analysis has been performed of penetrative convective instabilities arising from the combined action of thermal and centrifugal buoyancy forces. The theory allows for the fact that in the atmosphere, convection arising in an unstable layer may penetrate into a neighboring stable region. The objective has been to examine the effect of various mean temperature and velocity profiles on the critical limit and convective penetration of the disturbances. The linearized perturbation equations have been solved employing an approximate technique. The results obtained indicate that nonlinear profiles are more unstable and penetrative than linear ones. The close analyogy between streamline curvature and thermal stratification effects has been demonstrated. (Author)
