Direct numerical simulations of Rayleigh-Bénard flow with induced wall shearing have been performed on a 6912x3456x384 grid. Large coherent thermal structures emerge from the heated plate and meander. The vorticity formations are visualized with the Q-criterion. The zooms show small-scale structures in the flow.
