"August 1977." Includes bibliographical references (page 25). "A one-dimensional time-dependent PBL model is investigated. The model is based on the primitive equations with an eddy diffusivity closure for the turbulent fluxes of heat and momentum. Within the surface layer the constraints of Monin—Obukhov similarity theory are imposed. Surface heat flux is specified as the positive half cycle of a diurnal sinusoid. At the upper boundary, a strong inversion, a downward heat flux with 20% of the surface value is imposed. Predictions of the model are compared with observations from the Great Plains Experiment, O‘Neill, Nebraska, 25 August 1953. The comparison shows good general agreement"--Abstract.
