Weather Things: Haloes

The video explains the phenomenon of Halos, which are less noticeable than rainbows as they occur around the sun or moon. Halos form when light passes through ice crystals in cirrus clouds, refracting into a spectrum of colors. Unlike rainbows, the red color is inside the Halo ring. Various accessories to Halos, such as Parhelia (sun dogs), can appear depending on the type and alignment of ice crystals. Different arcs, like the Sercombe Horizon and tangent arc, are also discussed. At night, Halos are visible around the moon, but their accessories are harder to see.
