Abstract

A new theoretical approach to mountain flow is presented. The boundary value problem of stratified flow over a high ridge of arbitrary shape is solved by an iterative scheme using integral equations. The dynamical effects of boundary layer heating and cooling are also obtained. The shape as well as the size of a ridge is shown to be of importance for the resulting flow. The gross effect of boundary layer heating over the ridge is to dampen the perturbation in the airflow, while cooling has the reverse effect.
