The mathematical model for the 2D laminar flow is formed by the Navier-Stokes equations for incompressible fluid. The averaged Navier-Stokes equations for incompressible turbulent flow with addition of the equation of density change (Boussinesq model) were used as a mathematical model for stratified flow in ABL. Turbulent flow was modelled by means of the algebraic turbulence model.
