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.
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 manage a worldwide network of ~1800 active VLF radio wave receiver stations in 83 countries. [ 2 ]
Single sensor lightning detectors have been used on aircraft and while the lightning direction can be determined from a crossed loop sensor, the distance can not be determined reliably because the signal amplitude varies between the individual strokes described above, [11]: 115 and these systems use amplitude to estimate distance. Because the ...
VOR/DME eventually won the standardization effort, due to a number of factors. One was that the direct measurement systems like Loran were generally much more expensive to implement (and would be into the 1980s) while Decca had problems with static interference from lightning strikes because of its low 70 to 129 kHz frequency. The choice of VOR ...
The actual phenomenon that is sometimes called heat lightning is simply cloud-to-ground lightning that occurs very far away, with thunder that dissipates before it reaches the observer. [2] At night, it is possible to see the flashes of lightning from very far distances, up to 100 miles (160 km), but the sound does not carry that far. [3]
Across the city, lightning and rain lit up the night sky and made quite a fuss for the athletes at the 2024 Paris Games. On Aug. 1, the official TODAY Instagram shared photos of the brilliant ...

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 ...
