A process whereby low-level [[convergence]]  in the [[wind field]] produces [[convection]] and [[cumulus]] formation, thereby releasing [[latent heat|latent  heat]].</div><br/> <div class="paragraph">This enhances the convergence and further increases convection. The atmospheric [[environment]]  that favors CISK is found over warm, tropical oceans where there is an abundant supply of moisture,  the [[Coriolis force]] is small, and air convergence is strong.</div><br/> </div><div class="reference">Charney, J.
