Short summary
By using large-eddy simulation model data for 10 meteorological situations, we systematically studied the ability of current parameterizations to capture convective transport by clouds. We found that the currently applied parameterization for the cloud area fraction does not suffice and a novel parameterization is proposed. Furthermore, the scaling of the upward velocity and the parameterization for the concentrations of atmospheric reactants are improved.
