Abstract

Expressions for the equilibrium surface Bowen ratio (β s ) and equilibrium evaporation are derived for a growing convective boundary layer (CBL) in terms of the Bowen ratio at the top of the mixed layerβ i and the entrainment parameter A R . If AR is put equal to zero, the solution forβ s becomes-that previously obtained for the zero entrainment or ‘closed box’ model. The Priestley-Taylor parameter α is also calculated and plotted in terms ofA R andβ i . Realistic combinations of the atmospheric parameters give values of α in the range 1.1 to 1.4.
