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.
Typically, lightning discharges 30,000 amperes, at up to 100 million volts, and emits light, radio waves, x-rays and even gamma rays. [1] Plasma temperatures in lightning can approach 28,000 kelvins. Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet).
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.
"Lightning increases the atmosphere's ability to cleanse itself," the researchers wrote in the study. Many are familiar with the potentially deadly hazards posed by lightning, which is blamed for ...
Similar to the famous Miller-Urey experiment in 1953, the team simulated the conditions of early Earth in a laboratory, and studied the chemical reactions when simulated lightning strikes struck ...
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 ...
When lightning strikes someone, most of the current flashes across the surfac. Being struck by lightning can potentially kill or injure someone, resulting in cardiac arrest or damage to the ...
Dry lightning refers to lightning strikes occurring in this situation. ... When the higher levels of the atmosphere are cooler, and the surface is thus warmed to ...
