Why are there rings around the moon?The winter halo illuminates the sky in the San Francisco Bay Area



San Francisco (KGO)-Have you seen the halo effect or the sound that rang around the moon?

Meteorologist Drew Tuma said that this is the so-called moon ring, winter halo or 22-degree halo. At that time, “ice crystals suspended on thin, thin cirrus clouds refracted the moon’s light into a perfect The circle”.

Tuma added that this is common, “more common than rainbows.”

Weather.gov said that the halo around the sun or moon is usually regarded as a bright white ring, which may sometimes be colored.

Tuma suggested that we often miss the lunar halo, because there are very few people overnight.

“In folklore, it is said that the moon ring will warn of an impending storm,”

; Tuma wrote on Twitter.
