2. Terrestrial gamma-ray flash - Wikipedia

   en.wikipedia.org/wiki/Terrestrial_gamma-ray_flash

   The Atmosphere-Space Interactions Monitor (ASIM), dedicated to measuring simultaneously optical signals of lightning and signals of terrestrial gamma-ray flashes, revealed that TGFs are usually associated with optical flashes, strongly suggesting that relativistic electrons as precursors of TGFs are produced in the strong electric fields in the ...

3. Distribution of lightning - Wikipedia

   en.wikipedia.org/wiki/Distribution_of_lightning

   Global map of lightning frequency--strikes/km 2 /yr. The high lightning areas are on land located in the tropics. Areas with almost no lightning are the Arctic and Antarctic, closely followed by the oceans which have only 0.1 to 1 strikes/km 2 /yr. The map on the right shows that lightning is not distributed evenly around the planet. [5]

4. Upper-atmospheric lightning - Wikipedia

   en.wikipedia.org/wiki/Upper-atmospheric_lightning

   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.

5. Wallpaper - Wikipedia

   en.wikipedia.org/wiki/Wallpaper

   Wallpapers can come plain as "lining paper" to help cover uneven surfaces and minor wall defects, "textured", plain with a regular repeating pattern design, or with a single non-repeating large design carried over a set of sheets. The smallest wallpaper rectangle that can be tiled to form the whole pattern is known as the pattern repeat.

6. Lightning-prediction system - Wikipedia

   en.wikipedia.org/wiki/Lightning-prediction_system

   A Perry Weather lightning warning system. The detection equipment is designed to constantly survey atmospheric electrical activity and potential for lightning occurrence via radar and other methods. [citation needed] Storms are scanned by radar to determine the degree of electrification and potential for lightning occurrence. [citation needed]
