CONVECTIVE CLOUD

Cloud formation makes the convection process visible. An unstable atmospheric column will lead to updrafts. If the air below is moist, the updraft will lead to condensation into droplets. The condensation process accelerates the updraft owing to the release of latent heat. Examples are the various types of cumulus clouds (e.g., cumulus, cumulus congestus, cumulonimbus).
