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 ...
A return stroke, cloud-to-ground lightning strike during a thunderstorm. Cloud-to-ground lightning frequently occurs within the phenomena of thunderstorms and have numerous hazards towards landscapes and populations. One of the more significant hazards lightning can pose is the wildfires they are capable of igniting. [54]
This is extremely important, as Earth’s early atmosphere would’ve been made up of nonreactive N 2 molecules. Lightning was the essential piece needed to create the ingredients essential for ...
A key factor in the ignition of these wildfires is the type of lightning, with long-continuing-current (LCC) lightning being particularly significant. The risk of lightning-ignited wildfires is influenced not only by the occurrence of LCC lightning but also by the availability of dry fuel, which is influenced by how much rain has fallen before.
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 ...
