Shallow convection parameterization

From Glossary of Meteorology

shallow convection parameterization

The representation in a numerical model of the turbulent transports of heat and moisture by nonprecipitating cumulus clouds with cloud tops below 3000 m above the surface.

These shallow cumulus clouds are found all over the globe but they, and their associated turbulent transports, are of particular significance in the trade wind region where they provide the heat and moisture that maintains the thermodynamic structure of the lower troposphere.
See parameterization.
