Abstract: The study of regular waves in the work is reduced to the identification of statistical patterns, which are numerically expressed by the dependencies between waves elements and their determining factors. Based on the processing of data obtained using the ADCP, the characteristic length of the regular wave for the Azov Sea, the characteristic and maximum speed are revealed in the work. The paper calculates the turbulent exchange coefficients using set of periods for averaging turbulent velocity pulsations. Using experimental data on velocity components pulsations, the vertical turbulent exchange coefficient was calculated on the basis of various approaches to its parametrization, based on the analysis of the obtained coefficient distributions, the most adequate parametrization of the coefficient for physical processes was selected, which is used in the software package.

Keywords: effect of regular waves, turbulent exchange, vertical turbulent exchange coefficient, three-dimensional hydrodynamics mathematical model.
