  2. Lightning - Wikipedia

    en.wikipedia.org/wiki/Lightning

    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.

  3. Electric blue (color) - Wikipedia

    en.wikipedia.org/wiki/Electric_blue_(color)

    Electric blue is a color whose definition varies but is often considered close to cyan, and which is a representation of the color of lightning, an electric spark, and the color of ionized argon gas; it was originally named after the ionized air glow produced during electrical discharges, though its meaning has broadened to include shades of blue that are metaphorically "electric" by virtue of ...

  4. Upper-atmospheric lightning - Wikipedia

    en.wikipedia.org/wiki/Upper-atmospheric_lightning

    Upper-atmospheric lightning is believed to be electrically induced forms of luminous plasma. The preferred usage is transient luminous event (TLE), because the various types of electrical-discharge phenomena in the upper atmosphere lack several characteristics of the more familiar tropospheric lightning.

  5. Lightning strike - Wikipedia

    en.wikipedia.org/wiki/Lightning_strike

    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. A less common type of strike, ground-to-cloud (GC) lightning, is upward-propagating lightning ...

  6. St. Elmo's fire - Wikipedia

    en.wikipedia.org/wiki/St._Elmo's_fire

    Illustration of St. Elmo's fire on a ship at sea Electrostatic discharge flashes across the windscreen of a KC-10 cockpit.. St. Elmo's fire (also called witchfire or witch's fire [1]) is a weather phenomenon in which luminous plasma is created by a corona discharge from a rod-like object such as a mast, spire, chimney, or animal horn [2] in an atmospheric electric field.

  7. Sprite (lightning) - Wikipedia

    en.wikipedia.org/wiki/Sprite_(lightning)

    A sprite at the horizon, with lightning below in the troposphere and above the green line of airglow at the upper mesopause and border to space (the bright light above is the Moon). First color image of a sprite, taken from an aircraft. A sprite over Laos, as seen from the International Space Station. Sprites appear as luminous red-orange flashes.

  8. Earthquake light - Wikipedia

    en.wikipedia.org/wiki/Earthquake_light

    Earthquake light. An earthquake light also known as earthquake lightning or earthquake flash is a luminous optical phenomenon that appears in the sky at or near areas of tectonic stress, seismic activity, or volcanic eruptions. [1] There is no broad consensus as to the causes of the phenomenon (or phenomena) involved.

  9. Ionized-air glow - Wikipedia

    en.wikipedia.org/wiki/Ionized-air_glow

    Ionized-air glow. Nitrogen glow. Oxygen glow. Electrical discharge in air. Particle beam from a cyclotron. Ionized-air glow is the luminescent emission of characteristic blue–purple–violet light, often of a color called electric blue, by air subjected to an energy flux either directly or indirectly from solar radiation.
