Abstract

In the paper we discuss the results of the measurements of the nighttime optical turbulence parameters performed by the mobile astronomical telescope MEADE at the Large solar vacuum telescope of the Baykal Astrophysical Observatory site. Measurements have been performed in the clear sky, when the surface-layer wind speed < 2 m/sec. The studies of the optical turbulence in the nighttime are relevant for improving our knowledge about mechanisms of the turbulence generation and dissipation at this site. It is known that diurnal variations in the energy and momentum fluxes, turbulence strength are modulated by topography. Regional peculiarities of the energetic structure of atmospheric fluctuations (including optical turbulence) is the basis for development of the parametrization methods.
