CG lightning is the best known because, unlike other forms of lightning, it terminates on a physical object (most often the Earth), and therefore lends itself to being measured by instruments. Cloud to air lightning occurs at the top of clouds when the positive charged particles at the top of … In the Lightning has been observed within the atmospheres of other planets in our Solar System, such as Venus, Jupiter and Saturn. The term "heat-lightning" is often applied here, due to the association between locally experienced warmth and the distant lightning flashes. Heavier, negatively charged particles sink to the bottom of the This type of thunderstorm is often referred to as a "dirty thunderstorm" due to the high solid material (ash) content. thunder). In addition, improved measurement and observational capabilities were made possible thanks to improvements in space-based technologies. Click here to sign in with Lighting has also been observed on Saturn. And though roughly 90% of people struck by lightning survive, humans or animals struck by lightning may suffer severe injury due to internal organ and nervous system damage. They are believed to be the result of moist convection with Jupiter's troposphere, where convective plumes bring wet air up from the depths to the upper parts of the atmosphere, where it then condenses into clouds of about 1000 km in size. This discharge may produce a wide range of electromagnetic radiation, from very hot plasma created by the rapid movement of electrons to brilliant flashes of visible light in the form of black-body radiation. The This is like a static electricity sparks you see, but much bump into each other as they move around. When the opposite charges build up enough, this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we know as lightning. In this case, the lightning takes the form of a discharge between a thundercloud and the ground, and is usually negative in polarity and initiated by a stepped branch moving down from the cloud. It will make a flash of lightning. Scientist seeks new insights to study lightning, Melting ice patch in Norway reveals large collection of ancient arrows, A photonic crystal coupled to a transmission line via an artificial atom, New transient ultraluminous X-ray source detected in the galaxy NGC 7090, X-ray diffraction reveals details inside mummies without having to open them up, Physicist creates N95-type respirators using cotton candy machine. It can go from the cloud to the ground. As the air rises, water vapour cools and forms a cloud. Wilson also won the Nobel Prize for the invention of the Cloud Chamber, a particle detector used to discern the presence of ionized radiation. When Most lightning happens inside a cloud, but sometimes it happens For example, during the eruption of Vesuvius in 79 CE, Pliny the Younger noted several powerful and frequent flashes taking place around the volcanic plume. Or seen sparks By the summer of 1752, Franklin is believed to have conducted the experiment himself during a large storm that descended on Philadelphia. Lessons on light and sight for primary children. Thunder and lightning. In 2012, images taken by the Cassini probe in 2011 showed how the massive storm that wrapped the northern hemisphere was also generating powerful flashes of lightning. These include x-rays and gamma rays, which have been confirmed through observations using electric field and X-ray detectors, and space-based telescopes. In the case of Venus, the first indications that lightning may be present in the upper atmosphere were observed by the Soviet Venera and U.S. Pioneer missions in the 1970s and 1980s.

This discharge allows charged regions in the atmosphere to temporarily equalize themselves, when they strike an object on the ground. Once these electric fields become large enough, a giant "spark" occurs between them (or between them and the ground) like static electricity, reducing the charge separation.
