A Cell Dynamical System Model for Thundercloud Electrification
  A cell dynamical system model is developed for thundercloud electrification by consideration of microscopic domain eddy dynamical processes in the atmospheric boundary layer (ABL). This non-deterministic model based on cellular automata computational technique enables formulation of simple scale invariant governing equations for cloud electrical parameters in terms of non-dimensional steady state mass and momentum fluxes in the ABL.
