Abstract

New results of measurements of the characteristics of the turbulent atmosphere in the mountain conditions of the Sayan Solar Observatory are presented. The results were obtained during long-term observations in 2018-2019. The obtained experimental data are compared with the data of early long-term observations over the territories of high-altitude observatories in conditions of different reliefs, at different seasons, in different climatic and geographical regions. The new mobile hardware and software ultrasonic complex AMK-03-4, designed to measure the characteristics of turbulent weather fields, was used for the measurements. Experimental data are 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. The range of experimentally observed Monin-Obukhov numbers in the positive region, where previously experimental data were not available, is significantly expanded. Comparison of new data for 2018-2019 with the data of early observations, it confirms the propositions of the similarity theory in the anisotropic atmospheric boundary layer. The data obtained are useful for predicting the characteristics of turbulence in mountainous regions.
