ABSTRACT

An important feature of atmospheric moist convection is a possibility of buoyancy reversal. Buoyancy reversal results from the mixing of cloudy air and dry environmental air and subsequent evaporation of cloud droplets. Based on results from laboratory experiments, theoretical arguments and numerical simulations, it is argued that buoyancy reversal has a rather minor effect on the rate of entrainment despite the dramatic effects on the overall dynamics of buoyancy-reversing systems.
