  The connection between thunderstorms and relativistic runaway electron
avalanches is an important topic that has attracted the attention of many
researchers. Among other things, there are a lot of various simulations of the
dynamics of electron avalanches. This article was written mostly in response to
the article "The critical avalanche of runaway electrons" by Evgeny Oreshkin et
al, which shows rather large numbers for an estimate of the number of runaway
electrons, but it also contains the results of our own simulation and
comparison with other papers.
