Abstract

It is shown that the known experimental synoptic spectra of the atmospheric turbulence (spectrum of Van der Hoven, 1957; spectrum of Kolesnikov, Monin, 1965) represent the sum of the solitary spectra of coherent structures with various sizes (with variety outer scales). The spectrums registered by us near to a mirror of the Baikal Solar Vacuum Telescope (BSVT) of the Baikal astrophysical observatory and in a under dome room of the Big Alt-Azimuth Telescope (BТА) of the Special astrophysical observatory are presented too. Apparently, the good coincidence of theoretical spectrums with experimental data (from both parties from a micrometeorological maximum) is observed. This spectrum well approximates the experimental spectrums not only in the field of a micrometeorological interval of frequencies, but also on frequencies of lower, than a micrometeorological maximum where the observational spectrums have decrease.
