An example is developed to illustrate how atmospheric dynamics may naturally lead to stochastic behavior in precipitation. Due to a process in the atmosphere known as scale contraction, large fluctuations in precipitation may be induced by small mesoscale inhomogeneities in the initial temperature field. If the initial states of the participating air masses of a mid‐latitude cyclone are not well defined at the mesoscale, precipitation may be considered as a dynamic process subject to random initial conditions.
