【Abstract】 The evolution process of nocturnal radiation fogs and lower stratocumulus and their effects on the boundary layer structure are studied with the calculation of a model. This model takes account of the long-wave radiation fluxes of both liquid water and water vapor. The model mainly consists of two parts: a) an one-dimensional boundary layer model which is closured with the turbulent energy equation; b) the calculation of long-wave radiation fluxes. The calculated values are accordant with observed data.更多还原
