Summary

The equations for large-scale tropical flow, when averaged horizontally over a region large enough to contain an ensemble of clouds, include terms which represent the vertical convergence of the vertical eddy transport of sensible heat and of moisture. By assuming that these convergences are related to cumulus convection, the effect of an assumed population of cumulus clouds may be introduced into the large-scale model. The magnitude of the cumulus cloud effects must then be obtained from a cloud model, using predicted environmental parameters as input. In this investigation, the clouds are represented by a steady state plume model. Preliminary results, using assumed environmental parameters, are presented. (Author).
