Abstract: The mountainous terrain of Armenia contributes to thunderstorm formation there. Observations for more than a decade at the high (3200 m MSL) Aragats mountain station have demonstrated the presence of runaway electrons, accelerated downward by the electric field of the storm, to produce so-called Thunderstorm Ground Enhancements. More than 500 cases have been observed from 2012 to 2020.
