Short summary
Explicit simulations (LES) of cold pools formed by the re-evaporation of convective rainfall are compared with a parameterization developed for a climate model. The study demonstrates the relevance of the parameterization principles. Improvements to the scheme and automatic tuning of free parameters also lead to very good quantitative agreement between the LES and the parameterization.
