  A cell dynamical system model for the troposphere - ionosphere coupling is
proposed . Vertical mass exchange in the troposphere-ionosphere-magnetosphere
takes place through a chain of eddy systems. Any perturbation in the
troposphere would be transmitted to ionosphere and vice versa. A global
perturbation in ionosphere, as the one caused by solar variability, is
transmitted to troposphere influencing weather systems/geomagnetic/atmospheric
electrification processes.
