Wave clouds on a beach in Florida, formed by thick fog and wind against a row of highrises. February 5, 2011
The circumhorizon arc or 'rainbow clouds. This amazingly beautiful natural phenomenon can be observed when the sun rises high in the sky. The rays of the sun when it passes through high-altitude clouds composed of ice crystals in the form of hexagons. The sunlight is refracted in these crystals in bizarre way, and as a result, we see “fire rainbow”. This phenomenon is not local, it can extend over several hundred square miles
This is a rare meteorological phenomenon called a skypunch. When people see these, they think it's the end of the world. Ice crystals form above the high-altitude cirro-cumulo-stratus clouds, then fall downward, punching a hole in the cloud cover.
