WebThe rest of the frequency distributions (71.4 %), from the late 20th century and early 21st century, used lightning data from LLSs. The maximum proximity index (in 17 frequency distributions) and the minimum holdover time (in 10 frequency distributions) are the most recurrent criteria applied to select igniting lightning.
Lightning is not distributed evenly around Earth, as shown in the map. On Earth, the lightning frequency is approximately 44 (± 5) times per second, or nearly 1.4 billion flashes per year and the median duration is 0.52 seconds made up from a number of much shorter flashes (strokes) of around 60 to 70 microseconds. … See more Lightning is a naturally occurring electrostatic discharge during which two electrically charged regions, both in the atmosphere or with one on the ground, temporarily neutralize themselves, causing the instantaneous … See more The typical cloud-to-ground lightning flash culminates in the formation of an electrically conducting plasma channel through the air in … See more The best-studied and understood form of lightning is cloud to ground (CG) lightning.
