Recently, logarithmic mean temperature profiles have experimentally and numerically been found in turbulent Rayleigh-Bénard (RB) convection for large Rayleigh numbers beyond ∼ 1010. For very large Ra beyond 1014 these logarithmic profiles have been connected with the shear instability of the boundary layer. Here we offer an alternative interpretation of these profiles which also holds in the regime between 1010 < Ra < 1014 and connects them with plume hotspots.
