Mechanism of fire rainbow formation

Rainbows often appear when the weather is warm, the sun rises and there are clouds made of ice crystals in the sky.

This phenomenon often occurs in warm weather months.

The strange phenomenon in the lower video is called a fire rainbow, but it's not actually fire or rainbow. Its official name is the circumhorizontal arc , which occurs when the Sun rises at an angle of more than 58 degrees and in the sky there is a cloudy cloud, the cloud is shaped like thin white streaks.

Ti clouds are made of ice crystals at high altitudes, where temperatures are low. Light refracts through crystals, causing a rainbow-like phenomenon.

Normal rainbows form at low altitudes, when sunlight shines through small droplets.

Fire rainbows are very rare, often appearing in warm weather months.
