= Relativistic runaway electron avalanche
{wiki=Relativistic_runaway_electron_avalanche}
Relativistic runaway electron avalanche (RREA) is a phenomenon that occurs in strong electric fields, typically in the context of thunderstorm electrification, atmospheric electricity, or other high-energy physics systems. It involves the generation of high-energy electrons that can lead to an exponential increase in the number of secondary electrons through a process of ionization and acceleration.
