Abstract
The work discusses the optical turbulence structure and dynamics at the Baykal Astrophysical Observatory (BAO) site. The characteristics of the optical turbulence including Fried radius, isoplanatic angle are analyzed. Estimates of the variations of the height profiles of the air refraction index turbulent fluctuations at the Baykal Astrophysical Observatory are given. Using the mean height profile of the structure characteristic of the air refraction index turbulent fluctuations, diurnal variations of the Fried radius at the BAO site are estimated.
