Abstract : The formation of precipitation in warm cumulus clouds is most simply modeled by a uniform distribution of droplets falling at their terminal velocities in still air. However, it is known that storm clouds possess a large updraft and are turbulent in general. This memorandum discusses the possible mechanisms by which turbulence could affect the growth rate of droplets and reviews present research on this subject. (Author)
