Abstract : A diabatic surface boundary layer model valid for stationary, homogeneous conditions in stable and unstable air is developed from dynamic similarity of flows concept as applied to the lower portion of the atmosphere. The model is a development of the basic similarity theory of Monin and Obukhov and utilizes concepts advocated by McVehil, Panofsky and Pandolfo. It was found that a critical value of the gradient Richardson number exists at Ri = 0.223 and that the vertical gradients of wind and temperature are inversely proportional to height, to a negative power of the exchange coefficient ratio. The model is presented in tabular form over the stability range 0.220 > Ri > -5.00. (Author)
