Abstract Thermal convection between two horizontal walls kept at small amplitude non- uniform temperatures of the form, and with 1, is numerically investigated. When the Rayleigh number is small, an upright cell is formed between two walls at0; the cell is tilted at2, and a flow with two-tier- structure cells occurs at. As the Rayleigh number is increased, Nusselt number increases smoothly for0 and2, but increases rather steeply for near the critical Rayleigh number(1708). When the wave number is small(0.5), multicellular convection occurs over one wave length, for all phase differences, and multiple solutions are found.
