Application of Linear Thermodynamics to the Atmospheric System.Part Ⅱ: Exemplification of Linear Phenomenological Relations in the Atmospheric System

The linear phenomenological relations in the atmospheric boundary layer are proved indirectly usingobservational 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 correspondinglinear phenomenological coefficients. But the experimental facts show that the linear phenomenological rela-tions are not tenable in the atmospheric mixing layer because the turbalent transport process is an intensenon-linear process in the mixing layer. Hence the convection boundary layer is a thermodynamic state in anon-linear region far from the equilibrium state. The geostrophic wind is a special cross-coupling phenom-enon between the dynamic process and the thermodynamic process in the atmospheric system. It is a practi-cal exemplification ofa cross-coupling phenomenon in the atmospheric system.
