From the development pattern of this storm (confirmed by the storm that occurred on the previous day, May 24) we can conclude, that the RREAs are developing in a huge area in the thundercloud. Near the active lightning region, multiple RREAs are started (and consequently are registered as their surface offspring’s – TGEs), and they are frequently terminated by lightning flashes and restarted several times at recovering of the strong electric field. If the lightning active zone is far (>10 km) from particle detectors we observe long-lasting TGE (from the long-lasting parent RREAs) without their termination by lightning flashes. Thus, the typical TGE on Aragats covered an area where multiple TGEs occurred all terminated by lightning flashes, and a peripheral zone, where lightning activity is reduced allowing long-lasting TGEs to finish smoothly.
