| Abstract: | Some new results related to the theory of rising convective jets over heat and momentum sources are presented. The consideration is not restricted to free convective or forced jets—mixed situations are also possible. A known model is generalized to the case of a noticeable contribution of the effects of water-vapor buoyancy. It is established that a universal conservation law that is valid for any entrainment hypotheses exists. A simple approximate criterion of the possibility that jets “break” through barrier layers is derived. An analytic solution that describes a moist-adiabatic rise of a jet above the condensation level is found. The influence of jets on the transport of passive admixtures is assessed. A model is proposed for the horizontal spreading of the warm air transported by a jet below an intense barrier layer. |
