Abstract
Measurement results of main atmospheric parameters are given for different geographical areas and meteorological situations. A mobile ultrasonic meteosystem was used for the measurements. It is shown that turbulence in mountains has non-Kolmogorov character and pronounced features of coherent structure. The authors define coherent structures and specify their main properties. In particular, structure functions and values of the Kolmogorov and Obukhov constants vary for the coherent turbulence in comparison with the Kolmogorov incoherent one. The structure function of temperature fluctuations has been calculated on the base of model three-dimensional spectrum of coherent turbulence; the behavior of its asymptotes has been studied.
