A rare weather phenomenon known as ball lightning, or St. Elmo’s Fire, has been observed in nature for the first time by Chinese scientists.
Scientists in the Quinhai region of China were monitoring a thunderstorm in 2012 with video cameras and spectrometer, when they recorded the ball lightning.
Ball lightning is a lightning phenomenon that happens during thunderstorms. It’s rare and unpredictable, which is why researchers don’t know much about it. It can last more than a second, which is considered long-lived for lightning, but it’s hard to capture and study.
In layman’s terms, ball lightning is a big flash of light that looks circular that appears in the sky during a storm. It sometimes has a blue glow and can emanate from objects like lightning rods or ship masts.
