Trapped energetic electron curtains produced by thunderstorm driven relativistic runaway electrons

Relativistic runaway electron beams driven upward by intense lightning-gene rated quasielectrostatic (QE) fields undergo intense interactions with the background magnetospheric plasma, leading to rapid nonlinear growth of Lang muir waves. The beam electrons are strongly scattered by the waves in both pitch angle and energy, within one interhemispheric traverse along the Eart h's magnetic field lines. While those electrons within the loss cone precip itate out, most of the electrons execute bounce and drift motions, forming detectable trapped curtains of energetic electrons.
