Could macroscopic dark matter (macros) give rise to mini-lightning flashes out of a blue sky without clouds? [PDF]
Atmosphere 2021, 12, 1230, 2021 A recent study pointed out that macroscopic dark matter (macros) traversing through the earth's atmosphere can give rise to hot and ionized channels similar to those associated with lightning leaders. The authors of the study investigated the possibility that when such channels created by macros pass through a thundercloud, lightning leaders may locked

Theory of ball lightning [PDF]
Sci. Rep. 6, 28263 (2016), 2014 We present a comprehensive theory on the formation of ball lightning, a luminous sphere sometimes observed after normal lightning. In a ball lightning event, a relativistic electron bunch can be produced by the stepped leader of lightning and coherently emit high-power microwave when striking the ground.

Seasonal Predictability of Lightning over the Global Hotspot Regions [PDF]
, 2021 Skillful seasonal prediction of lightning is crucial over several global hotspot regions, as it causes severe damages to infrastructures and losses of human life. While major emphasis has been given for predicting rainfall, prediction of lightning in one season advance remained uncommon, owing to the nature of the problem, which is short-lived local ...
