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.
Lightning is a natural phenomenon, more specifically an atmospheric electrical phenomenon. It consists of electrostatic discharges occurring through the atmosphere between two electrically charged regions, either both existing within the atmosphere or one within the atmosphere and one on the ground, with these regions then becoming partially or wholly electrically neutralized.
Lightning strikes are grouped into four categories: direct strikes, side splash, contact injury, and ground current. [1] Direct strike: lightning directly hits the person Orifice entry: may occur if lightning strike occurs near the head entering eyes, ears and mouth to flow internally
A ground current, the electricity that flows through the ground away from the point where lightning strikes, puts anyone nearby the strike at risk of shock. Ground currents affect a much larger ...
The lightning may be too far away to discern individual flashes. 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 ...
According to the agency, at least 36,597 cloud-to-cloud lightning were recorded till 5pm, while cloud-to-ground strikes were recorded at 25,753. Lightning that occurs between two or more separate ...
A rare August thunderstorm brought upwards of an inch of rain to Oregon on Saturday while also raking the state with 3,379 lightning strikes.
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]
