Turbulent scales of the similarity theory of Monin - Obukhov in the mountain anisotropic boundary layer

In order to predict the propagation of shortwave electromagnetic waves (including optical ones) in the atmosphere, the studies of the characteristics of mountain turbulence have been made. For this purpose, multiyear observations of day and night stratifications of the turbulent atmosphere in the Sayan Solar Observatory were continued. A new mobile hardware-software ultrasonic complex AMK-03-4 designed to measure the characteristics of turbulent meteorological fields was used for measurements. New experimental data have been obtained for the turbulent scales of velocity V _* (friction velocity) and temperature T _*, which are important characteristics of turbulence in the Monin - Obukhov similarity theory. Comparison of the experimental results with the data obtained by the authors earlier at different times in different climatic and geographical regions was made. The positions of the similarity theory in the atmospheric boundary layer are experimentally confirmed. It is shown that the traditional similarity theory can be extended to any anisotropic (in particular, mountain) boundary layer. This solves the problem of forecasting the characteristics of turbulence in the anisotropic layer, including mountain regions.
