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]
Animated map of a storm front over Central Europe on 16 August 2020 based on data from Blitzortung.org. Blitzortung ( German for "lightning direction-finding ", German pronunciation: [ˈblɪtsˌɔʁtʊŋ]) is an informal, non-commercial group of citizen scientists supported by professional scientists. Active since 2005, [1] station operators ...
Lightning is a natural phenomenon formed by electrostatic discharges through the atmosphere between two electrically charged regions, either both in the atmosphere or one in the atmosphere and one on the ground, temporarily neutralizing these in a near-instantaneous release of an average of between 200 megajoules and 7 gigajoules of energy, depending on the type.
A lightning strike or lightning bolt is a lightning event in which the 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 ...
Lightning is infrequent, 6–10 cloud-to-ground strikes in a five-minute period. 4. Scattered thunderstorms. Lightning is frequent, 11–15 cloud-to-ground strikes in a 5-minute period. 5. Numerous thunderstorms. Lightning is frequent and intense, greater than 15 cloud-to-ground strikes in a five-minute period. 6.
A lightning detector is a device that detects lightning produced by thunderstorms. There are three primary types of detectors: ground-based systems using multiple antennas, mobile systems using a direction and a sense antenna in the same location (often aboard an aircraft), and space-based systems. The first such device was invented in 1894 by ...
The August 2020 California lightning wildfires (also referred to as the August lightning siege or August wildfire siege) were a series of 650 wildfires that ignited across Northern California in mid-August 2020, due to a siege of dry lightning from rare, massive summer thunderstorms, which were caused by an unusual combination of very hot, dry air at the surface, dry fuels, and advection of ...
Sprite (lightning) Not to be confused with Sprite (computer graphics). A sprite at the horizon, with lightning below in the troposphere and above the green line of airglow at the upper mesopause and border to space (the bright light above is the Moon). Sprites or red sprites are large-scale electric discharges that occur in the mesosphere, high ...
