Abstract
A model is developed to account for regional scale vertical transport of pollutants from the mixed layer to the overlying free troposphere by an ensemble of non-precipitating cumulus convective clouds. The model determines acceptable cloud classes for given atmospheric state represented by the moist static energy distribution. The cloud classes are defined by dry entrainment rate, cloud depth and convective cloud amounts. The clouds are of course driven by regional scale heat and moisture convergence. Empirical data was collected and used to formulate a closure scheme to obtain the necessary cloud parameters. A statistical model which predicts the vertical distribution of cloud amount from cloud base was developed. The vertical variation of cloud amounts depends on the distribution of clouds having different depths.
