<p>Thunderstorm ground enhancements (TGEs) registered on Aragats research station (530 events during &#160;2008-2021) are frequently interrupted by the nearby lightning flashes. We are monitoring charged and neutral particle fluxes, near-surface electric field, distance to lightning flash, and numerous meteorological parameters 24/7. Our datasets [1,2] contains 165 TGEs interrupted mostly by the negative cloud-to-ground discharges (-CGs: 50%, inverted intracloud (IC) flashes followed by &#8211;CGs: 21%, inverted ICs: 18%, normal ICs:11%). The mean distance to the lightning flash estimated by EFM-100 electric mill is 5.8 +/- 3.1 km (based on 130 TGEs). Mean distance, estimated by a smaller subsample (18 TGEs) of this dataset, which contains also an estimate made by the worldwide lightning located network (WWLLN) is 6.6 +/- 5.6 km, by EFM &#8211; 4.5 +/- 2.6 km. The times of lightning occurrences measured by Aragats facilities and by the WWLLN coincide within a few microseconds. TGEs were interrupted by lightning during positive and negative near-surface electric fields. The TGEs which started at the negative (positive) near-surface electric field and terminated during the positive (negative) electric field were also observed.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
