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.
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 strike, ground-to-cloud (GC) lightning, is upward-propagating lightning ...
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 ...
It occurs over and around Lake Maracaibo, typically over a bog area formed where the Catatumbo River flows into the lake. [4] The phenomenon sees the highest density of lightning in the world, at 250 per km 2. [5] In summers, the phenomenon may even occur as dry lightning without rainfall. [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
A squall line is an elongated line of severe thunderstorms that can form along or ahead of a cold front. [25] [26] In the early 20th century, the term was used as a synonym for cold front. [27] The squall line contains heavy precipitation, hail, frequent lightning, strong straight line winds, and possibly tornadoes and waterspouts. [28]
Astronomers used the James Webb Space Telescope to spot a Milky Way-like galaxy that formed soon after the big bang created the universe.
