Data on the velocities of currents in Lake Baikal were used to calculate the zonal component of the coefficient of turbulent exchange and the dissipation rate of turbulent energy. We determined the empirical dependencies of the coefficients of turbulent exchange on the magnitude of the phenomenon, and on the mean flow velocity. We investigate the spatio-temporal variability of the coefficients of horizontal turbulent exchange and the dissipation rate of turbulent energy in the lake. Data on seasonal variability of the dissipation rate of turbulent energy were obtained for the first time.

Keywords: flow velocity, coefficient of turbulent exchange, dissipation rate.
