| Abstract: | A conductive-radiative model is used to predict the formation and growth of radiation fog. This is accomplished by solving numerically the heat and mass transport equations in conjunction with an approximate form of the radiative transfer equation. The equations of motion in simplified form are included in the physical system to make use of Blackadar's (1962) formulation of the exchange coefficient of the boundary layer.It is found for a number of hypothetical test cases that the model gives results which appear to represent real physical conditions. One actual situation is tested. Results show that the model reproduces better than qualitatively those parameters which are obtained from routine observations. |
