Phase transformation and precipitation formation in mixed phase clouds are usually associated with the Wegener Bergeron-Findeisen (WBF) process in which
ice crystals grow at the expense of liquid droplets. The evolution of mixed-phase clouds,
however, is closely related to local thermodynamical conditions, and the WBF process is just one
of three possible scenarios. The other two scenarios involve simultaneous growth or evaporation
of liquid droplets and ice particles. Particle evolution in the other two scenarios differs
significantly from that associated with the WBF process. Thus, during simultaneous growth, liquid
droplets compete for the water vapor with the ice particle, which slows down the depositional
growth of ice particles instead of promoting their growth at the expense of the liquid as in the
WBF process. It is shown that the WBF process is expected to occur under a limited range of
conditions and that ice particles and liquid droplets in mixed-phase clouds are not always
processed in accordance with the WBF mechanism.
