For 12 years we monitored particle fluxes on Mt. Aragats 7/24 and discovered the most
powerful natural electron accelerator operated in the thunderclouds. This natural electron
accelerator provided more than 450 Thunderstorm Ground enhancement events (TGEs). We
make exhausting analysis of these events and will present yearly and monthly distributions,
as well the day hour distributions. Also, we will present the distribution of the outside
temperature and precipitation occurrences which are correlated with particle fluxes. We
address questions about TGE evolution and atmospheric conditions supporting the
origination of the relativistic runaway electron avalanches and demonstrate the relativistic
runaway electron avalanche is possible on Aragats only in Spring-Autumn seasons.
