Attention is focused on the case in which the thickness of both sublayers (stable and unstable) is identical, which was not investigated before. Influence of stratification is more evident at small values of Rayleigh numbers (large values of Ekman numbers), at large Rayleigh numbers is almost negligible. For small Rayleigh numbers in the case of uniform stratification a large-scale columnar convection is developed in the whole volume, in the case of non-uniform stratification it is suppressed to the unstably stratified region but slightly penetrates to the stably stratified one, except the case of large Prandtl numbers when the convection significantly penetrate to the stably stratified region.
