Representation of upper-atmospheric lightning and electrical-discharge phenomena Discovery image of a TLE on Jupiter by the NASA Juno probe. [1]Upper-atmospheric lightning and ionospheric lightning are terms sometimes used by researchers to refer to a family of short-lived electrical-breakdown phenomena that occur well above the altitudes of normal lightning and storm clouds.
However, they are cold plasma phenomena that lack the hot channel temperatures of tropospheric lightning, so they are more akin to fluorescent tube discharges than to lightning discharges. Sprites are associated with various other upper-atmospheric optical phenomena including blue jets and ELVES. [1]
During the Soviet Venera and U.S. Pioneer missions of the 1970s and 1980s, signals suggesting lightning may be present in the upper atmosphere were detected. [130] The short Cassini–Huygens mission fly-by of Venus in 1999 detected no signs of lightning, but radio pulses recorded by the spacecraft Venus Express (which began orbiting Venus in ...
"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 ...
Upper-atmospheric lightning, including red sprites, Blue jets, and ELVES; Water sky; A double rainbow at Minsi Lake, Pennsylvania. A sun pillar in Finistère, Brittany.
Ground flashes produced in this manner tend to transfer high amounts of charge, and this can trigger upward lightning flashes and upper-atmospheric lightning. [1] Ball lightning may be an atmospheric electrical phenomenon, the physical nature of which is still controversial.
Atmospheric tides dominate the dynamics of the mesosphere and lower thermosphere, serving as an important mechanism for transporting energy from the upper atmosphere into the lower atmosphere. Terrestrial aeronomers study atmospheric tides because an understanding of them is essential to an understanding of the atmosphere as a whole and of ...
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).
