Thunderstorms produce beams of antimatter particles that rain into space, NASA scientists said this week, shedding more light on one of the weirdest Earth physics stories of recent memory.
Terrestrial gamma-ray flashes, which are brief, powerful bursts produced inside thunderstorms, apparently produce high-speed streams of electrons and positrons that are swept up in Earth’s magnetic field. Scientists are still not sure how TGFs work or how lightning enters the equation, however.
Snowstorms do produce thunder and lightning - only less frequently than summertime thunderstorms. Also, snowflakes - with a larger surface than raindrops - scatter sound and light more efficiently. In addition, visibility during snowstorms is often very low, making the flashes harder to see.
