What is a straight rainbow called?

This type of rainbow is known as a circumhorizontal arc. The physics behind how these horizontal rainbows form is quite different than that of the typical rainbow. This optical phenomenon is brought on by the way in which light passes through suspended ice crystals in the atmosphere.

What does a straight up rainbow mean?

Halos and rainbows are not a distraction, they are refraction. There is another phenomenon related to the Halo but you have to look almost straight up to see it. It is called a Circumzenith arc. It looks like an upside down rainbow but it only happens in thin Cirrus clouds when the sun is low.

What does it mean when a rainbow goes straight up and down?

Bottom line: When you see what looks like an upside-down rainbow, you’re likely seeing a circumzenithal arc. It’s related to the halos often seen around the sun or moon, caused by ice crystals in the upper atmosphere.

Is there such a thing as a vertical rainbow?

The arc isn’t a rainbow in the traditional sense—it is caused by light passing through wispy, high-altitude cirrus clouds. The sight occurs only when the sun is very high in the sky (more than 58° above the horizon).

What is a quadruple rainbow?

A quaternary rainbow forms when sunlight enters and reflects out of raindrops four times. With each pass through the raindrops, the amount of light is reduced, making tertiary and quaternary rainbows incredibly dim. Conditions have to be just right for them to form—heavy rain in addition to direct sunlight.

What is an upside-down rainbow called?
