Abstract: In the Boussinesq approximation, free inertia–gravity internal waves are considered while taking into account turbulent viscosity and diffusion in a plane-parallel flow perpendicular to the direction of wave propagation. For homogeneous stratification and with a constant flow velocity shear, the boundary value problem for the vertical velocity amplitude is analytically solved and the dispersion relation is found. The imaginary part of the wave frequency is negative; i.e., the wave is fading. The vertical wave momentum fluxes and the velocity of the Stokes drift of liquid particles are determined. Accounting for turbulent viscosity and diffusion somewhat increases the vertical wave momentum flux, while the Stokes drift velocity, on the contrary, decreases it. © 2022, Pleiades Publishing, Ltd.
