Abstract
The results of numerical simulation of some features of the structure of the nocturnal atmospheric boundary layer over the urbanized surface are presented. The mesoscale model includes improved nonlocal parametrization of turbulence developed based on the three-parameter model of turbulence. The turbulent Prandtl number appears to be stably dependent on the gradient Richardson number, and the vertical turbulent heat transport is contragradient. It was shown that the structural features of an “upside-down” boundary layer are detected in the stable atmospheric boundary layer.
