Dynamics of cosmic rays in the atmospheric electrostatic field and production of particles by thunderclouds
Acceleration of particles in the atmospheric electrostatic field is considered taking into account multiple elastic scattering. The critical field strength necessary for implementing runaway effect of charged particles under different initial conditions is analytically obtained. The process of cyclic particle production in strong thunderstorm fields is considered. It is shown that this mechanism can be used to describe the strong increases (sometimes with exponential segments) observed during thunderstorms in the intensity of the soft component.
