In this paper, we consider a three-dimensional model of wind currents in a reservoir using a system of complete nonlinear equations of hydrothermodynamics written in traditional approximations. The analysis is carried out for the model in a dimensionless form with the exclusion of advective and diffusion terms from the system of equations. The problem is considered in a rectangular area with the assignment of the tangential stress of wind friction in a special way, which makes it possible to investigate complex wind situations. Under the above constraints, analytical exact solutions were found for the barotropic and "additional", as well as the vertical velocity component for the wind flow model. A solution is presented with constant wind exposure. In addition, in this work, the components of the shear stress of wind friction are set in accordance with a special law that allows us to describe rather complex wind situations, and an analytical solution of the stationary and non-stationary problem is obtained.
