A mathematical and numerical investigation of the flow over 2D and 3D hilly terrain in the atmospheric boundary layer (ABL) is presented including comparison with an experiment. Mathematical model is based upon the RANS equations for an incompressible flow with an algebraic turbulence closure and given boundary conditions. Also additional transport equations for concentration and potential temperature have been considered. The artificial compressibility method with conjunction of~finite volume method and the explicit Runge--Kutta multistage scheme is used for numerical analysis.
