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. Upper-atmospheric lightning is believed to be electrically induced forms of luminous plasma. The preferred ...
Lightning primarily occurs when warm air is mixed with colder air masses, [21] resulting in atmospheric disturbances necessary for polarizing the atmosphere. [22] The disturbances result in storms , and when those storms also result in lightning and thunder, they are called a thunderstorm .
Sympathetic lightning is the tendency of lightning to be loosely coordinated across long distances. Discharges can appear in clusters when viewed from space. [22] [23] [24] [clarification needed] Upward lightning or ground-to-cloud lightning is a lightning flash which originates from the top of a grounded object and propagates upward from this ...
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]
A radio atmospheric signal or sferic (sometimes also spelled "spheric") is a broadband electromagnetic impulse that occurs as a result of natural atmospheric lightning discharges. Sferics may propagate from their lightning source without major attenuation in the Earth–ionosphere waveguide , and can be received thousands of kilometres from ...
Atmospheric electricity involves both thunderstorms, which create lightning bolts to rapidly discharge huge amounts of atmospheric charge stored in storm clouds, and the continual electrification of the air due to ionization from cosmic rays and natural radioactivity, which ensure that the atmosphere is never quite neutral. [6]
"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 ...
Regular, cyclical phenomena include seasons and atmospheric circulation. climate change is often semi-regular. Lightning strikes during the eruption of the Galunggung volcano in 1982
