We consider natural convection of viscoplastic fluids in a vertical channel with differentially heated side walls. Further to the horizontal gradient, a linear vertical temperature gradient is imposed on both walls to facilitate the study of the buoyancy layers forming on the walls. We show that for sufficiently small yield stress, a boundary layer forms on each wall. Asymptotic techniques are then used to describe the behaviour of the boundary layer as yield stress and stratification parameter vary.
