  2. Sprite (lightning) - Wikipedia

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

    Sprites or red sprites are large-scale electric discharges that occur in the mesosphere, high above thunderstorm clouds, or cumulonimbus, giving rise to a varied range of visual shapes flickering in the night sky. They are usually triggered by the discharges of positive lightning between an underlying thundercloud and the ground.

  3. Atmospheric optics - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_optics

    The color of light from the sky is a result of Rayleigh scattering of sunlight, which results in a perceived blue color. On a sunny day, Rayleigh scattering gives the sky a blue gradient , darkest around the zenith and brightest near the horizon.

  4. Lightning - Wikipedia

    en.wikipedia.org/wiki/Lightning

    Lightning at a sufficient distance may be seen and not heard; there is data that a lightning storm can be seen at over 160 km (100 miles) whereas the thunder travels about 32 km (20 miles). Anecdotally, there are many examples of people describing a 'storm directly overhead' or 'all-around' and yet 'no thunder'.

    There are many phenomena that result from either the particle or the wave nature of light. Some are quite subtle and observable only by precise measurement using scientific instruments. Some are quite subtle and observable only by precise measurement using scientific instruments.

    It takes all the colors of the rainbow for us to see it that way. It happens because of something called the Rayleigh effect, or Rayleigh scattering, named after a British scientist who first ...

    en.wikipedia.org/wiki/Heat_lightning

    Distant lightning near Louisville, Kentucky. Heat lightning (not to be confused with dry thunderstorms, which are also often called dry lightning) is a misnomer [1] used for the faint flashes of lightning on the horizon or other clouds from distant thunderstorms that do not appear to have accompanying sounds of thunder. Heat lightning in Tokyo

  8. 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 ...

  9. Atmospheric electricity - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_electricity

    Cloud-to-ground lightning. 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).
