In general, the mutual heating of components in a close binary system gives rise to rapid motions in their atmospheres. A simple model of this circulation is constructed, assuming axial symmetry and treating the incident radiation as a perturbation. The flow speeds decrease exponentially with optical depth, but are unrealistically high near the surface if the flow is taken to be laminar. A shear-flow instability gives rise to a turbulent surface layer, for which an order-of-magnitude model is constructed. It is pointed out that radiative cooling may have a major influence on the structure of the turbulent shear flow and that the turbulence may be much weaker than suggested in an earlier paper on rotationally driven circulation.
