註釋In the present study, the author derives the equations for a model for operational forecasting in the tropics. A vertically integrated boundary layer model is used, together with a multilevel free air model, and and it is assumed that their interface represents cumulus cloud bases. Whenever the model predicts the existence of cumulus clouds (conditional instability, saturation, upward vertical velocity at the top of the boundary layer), a system of cloud equations is solved in order to calculate the latent heating, evaporation, and divergence of eddy heat flux effects on the free air motions.
