Global map of lightning frequency--strikes/km 2 /yr. The high lightning areas are on land located in the tropics. Areas with almost no lightning are the Arctic and Antarctic, closely followed by the oceans which have only 0.1 to 1 strikes/km 2 /yr. The map on the right shows that lightning is not distributed evenly around the planet. [5]
Although sometimes used figuratively, the idea that lightning never strikes the same place twice is a common myth. In fact, lightning can, and often does, strike the same place more than once. Lightning in a thunderstorm is more likely to strike objects and spots that are more prominent or conductive.
Smooth channel lightning is an informal term referring to a type of cloud-to-ground lightning strike that has no visible branching and appears like a line with smooth curves as opposed to the jagged appearance of most lightning channels. They are a form of positive lightning generally observed in or near the convective regions of severe ...
The presence of multiple bolts shows this is a time-exposure photograph. A lightning strike or lightning bolt is a lightning event in which an electric discharge takes place between the atmosphere and the ground. Most originate in a cumulonimbus cloud and terminate on the ground, called cloud-to-ground (CG) lightning. A less common type of ...
It is now known that positive Lichtenberg figures have longer, branching structures because long sparks within air can more easily form and propagate from positively charged high-voltage terminals. This property has been used to measure the transient voltage polarity and magnitude of lightning surges on electrical power lines. [6]
A new study suggests that cloud-to-ground lightning likely provided the necessary material for the first organisms on Earth to form. All Life on Earth Might Have Started From Lightning, Scientists Say
An unusually strong solar storm hitting Earth produced stunning displays of color in the skies across the Northern Hemisphere early Saturday, with no immediate reports of disruptions to power and ...
