Application of linear thermodynamics to the atmospheric system. Part II: exemplification of linear phenomenological relations in the atmospheric system

Abstract

The linear phenomenological relations in the atmospheric boundary layer are proved indirectly using observational facts to combine linear thermodynamic theory and similarity theory in the boundary layer. Furthermore, it is proved that the turbulent transport coefficients are in proportion to the corresponding linear phenomenological coefficients. But the experimental facts show that the linear phenomenological relations are not tenable in the atmospheric mixing layer because the turbulent transport process is an intense non—linear process in the mixing layer. Hence the convection boundary layer is a thermodynamic state in a non—linear region far from the equilibrium state. The geostrophic wind is a special cross—coupling phenomenon between the dynamic process and the thermodynamic process in the atmospheric system. It is a practical exemplification of a cross—coupling phenomenon in the atmospheric system.
