... Лаборатория космических лучей . ... КЛПВЭ" . ... Multiple observations of Blue Jets (BJ)) show that BJ emits a fan of streamers similar to a laboratory leader. ... It was also noticed that BJ are similar to the streamer zone of a leader (streamer corona) and the modeling studies based on the streamers fractal structure were conducted. ... This similarity analysis has been done in three steps: First we described the dendritic structure of streamers in corona discharge applying the fractal theory. ...
