Results of an extensive investigation of probability distribution functions (pdf’s) for Rayleigh–Benard convection, in the hard turbulence regime, are presented. It is seen that the pdf’s exhibit a high degree of internal universality. In certain cases this universality is established within two Kolmogorov scales of a boundary. A discussion of the factors leading to universality is presented.
