Turbulence, entrainment, and mixing in cloud dynamics

  • James W. Telford
Article

Abstract

The various models that have been proposed for describing the dynamical development of small cumuli are discussed in terms of how well they predict the observed distribution of liquid water. The entrainment concept is examined and shown to involve contradictions when applied to growing blobs. An alternative process is offered in which the dominating factor in the cloud dynamics is the mixing in of drier overlying air down through the cloud until temporary static equilibrium is established. Consideration of the mixing process and calculations of the required dilution show this process can lead to the observed liquid water distributions.
