Abstract
An approximate infra-red radiation scheme, employing essentially the ‘cooling to space’ approximation, is included in a one-dimensional model of the atmospheric boundary layer. The approximate scheme is found not to produce significant errors in the behaviour of the dynamical model when integrated over a few hours. Radiative cooling is shown to be important in the development of a clear well-mixed layer which is capped by an essentially dry region; in particular, convetive instability is induced and this enhances the rate of entrainment of dry air. The development of fog is found to require sound models of both radiative transfer and turbulent diffusion.
