Weather Tidbits: Halo
This Weather Tidbits explores the sky phenomenon, known as the halo. A halo is a ring of light encircling and extending outward from the sun or moon. They are produced when the light is refracted, as it passes through ice crystals. They are associated with high clouds and happen more with the sun than the moon. The most common halo is the 22°, but depending on the angle of the sun or shape of the crystals, a 9° or 46° halo can occur.
