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]
The place on Earth where lightning occurs most often is over Lake Maracaibo, wherein the Catatumbo lightning phenomenon produces 250 bolts of lightning a day. [82] This activity occurs on average, 297 days a year. [83]
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 ...
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
Lightning currents have a very fast rise time, on the order of 40 kA per microsecond. Hence, although lightning is a form of direct current, conductors of such currents exhibit marked skin effect as with an alternating current, causing most of the currents to flow through the outer surface of the conductor.

When seen from Earth, lightning appears both powerful and majestic, but when viewed from space, it can seem a little ghostly. Astronaut spots 'spooky' lightning on Earth from space Skip to main ...
Teague, Texas, was named the lightning capital of the U.S. with over 1,900 occurrences of lightning per square mile in 2024, according to Vaisala, a global technology company.
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]
