What is a diffused rainbow?
This is "fire clouds" or "Rainbow clouds". They occur when sunlight diffracts off water droplets in the atmosphere and often appear in the late afternoon, on very hot and humid days. They're not… Beautiful Sunset. Nature Pictures.
What happens when a rainbow is diffused by raindrops?
When sunlight passes through raindrops in the sky, the light is split into the colors the rainbow. If you have the right angle, you can see the full band of rainbow stretch across the sky. Sometimes you can even see the mirror image of the band, or the full double rainbow.
What do you call a rainbow in a cloud?
Iridescent clouds, known as "fire rainbows" or "rainbow clouds," occur when sunlight diffracts off water droplets in the atmosphere. And the recipe for these heavenly sights is actually pretty simple. Like common cloud-to-ground rainbows, iridescent clouds usually accompany thunderstorms.
What is a rainbow without rain called?
Pierre Trottier) If you happened to look up at the sky this past weekend, you might have noticed a rare and beautiful sight: iridescent rainbow clouds, but not a drop of rain in sight. This phenomenon is known, fittingly, as cloud iridescence or irisation.

How rare is a double rainbow?
As mentioned before, many people believe a double rainbow is one of the rarest phenomena to witness. However, they're not as rare since in most cases, the double rainbow is there; we just can't see it. Double rainbows form in the same way as a single rainbow.
How rare is a fire rainbow?
As mentioned above, fire rainbows are rare. The source of light—the Sun (or Moon)—needs to be at least 58o above the horizon, meaning that fire rainbow is almost impossible to see in places north of 55oN or south of 55oS.
What is a Moonbow?
A moonbow (sometimes known as a lunar rainbow) is an optical phenomenon caused when the light from the moon is refracted through water droplets in the air. The amount of light available even from the brightest full moon is far less than that produced by the sun so moonbows are incredibly faint and very rarely seen.
What is a Sundog rainbow?
A sundog is similar to a rainbow, and more common than rainbows. Sometimes they look like bright rainbows or colorful spots on either side of the Sun. Other times they are brighter and actually look like two extra Suns. Sundogs are also known as “mock suns” or “parhelia,” which means “with the Sun”.
What is an ice rainbow?
Known scientifically as a 'halo phenomenon', the rainbow pillar is formed by light interacting with ice crystals suspended in the atmosphere. Ghostly: The rainbows are formed by ice crystals ( Elena Sellberg/Solent News & Photo Agency)
What is the rarest rainbow?
Twinned rainbows The rarest type of rainbow start from the same base but them split along the arc to form a primary and secondary rainbow. Twinned rainbows are formed when sunlight is refracted after coming into contact with two rain showers which have different size of droplets from each other.
What is a 360 degree rainbow called?
There is something called as Halo which can be termed as circular rainbows as well. Halos can have many forms, ranging from colored or white rings to arcs and spots in the sky. Many of these appear near the Sun or Moon, b.
What is a reverse rainbow?
They're called circumzenithal arcs, and they're not really rainbows. Instead, they're caused by ice crystals in the upper atmosphere. These arcs are related to the frequently seen halos around the sun or moon.
What is a lunar rainbow?
We've all seen rainbows. But have you ever seen a moonbow? This rare phenomenon, also known as a lunar rainbow, occurs at night when light from the Moon illuminates falling water drops in the atmosphere. Sometimes the drops fall as rain, while in other cases the mist from a waterfall provides the necessary water.
What is a triple rainbow?
On rare occasions rays of light are reflected three times within a rain drop and a triple rainbow is produced. There have only been five scientific reports of triple rainbows in 250 years, says international scientific body the Optical Society.
Is a fire rainbow real?
Fire rainbows occur only when the sun is very high in the sky (more than 58° above the horizon). What's more, the hexagonal ice crystals that make up cirrus clouds must be shaped like thick plates with their faces parallel to the ground.
Are fire rainbows rare?
As mentioned above, fire rainbows are rare. The source of light—the Sun (or Moon)—needs to be at least 58o above the horizon, meaning that fire rainbow is almost impossible to see in places north of 55oN or south of 55oS.
What is a ghost rainbow?
A fogbow, or white rainbow Fogbows are sometimes called white rainbows, or cloudbows or ghost rainbows. They're made much as rainbows are, from the same configuration of sunlight and moisture. Rainbows happen when the air is filled with raindrops. You always see a rainbow in the direction opposite the sun.
How rare is a triple rainbow?
On rare occasions rays of light are reflected three times within a rain drop and a triple rainbow is produced. There have only been five scientific reports of triple rainbows in 250 years, says international scientific body the Optical Society.
What are twin rainbows?
A twin rainbow is when one splits in to two separate bows. Google software engineer Iman Sadeghi performed research on the physics of rainbows at the University of California, San Diego for his doctorate. He created software that was able to simulate rainbows and the way they occur in nature.
Are Moonbows rare?
Lunar rainbows — moonbows — occur less than 10 percent as often as normal rainbows. Moonbows need a few additional conditions to form, which is why they're so rare. Although well known, rainbows themselves are not common — most places see fewer than six in a year.
Are horizontal rainbows rare?
In the United States it is a relatively common halo, seen several times each summer in any one place. In contrast, it is a rare phenomenon in northern Europe for several reasons.
Are there ever triple rainbows?
On rare occasions rays of light are reflected three times within a rain drop and a triple rainbow is produced. There have only been five scientific reports of triple rainbows in 250 years, says international scientific body the Optical Society.
What is a pink rainbow?
The pink appearance of the rainbow is a result of the lower sun at sunrise and sunset. 'Rainbows witnessed at dawn and dusk can, on occasion, be pink because of the low sun angle at that time of day,' said BBC Weather expert Lan Boutland. read more.
How rare is a quadruple rainbow?
The quadruple rainbow phenomenon is extraordinarily rare. In 2011, LiveScience reported that only five third- and fourth-level rainbows had ever been recorded in 250 years. Rainbows are formed by light reflected from rain droplets.
What is a Snowbow?
The fact is that there are snowbows, the ice-crystal analog to rainbows. A snowbow is a fairly rare phenomenon that forms when sunlight is reflected and refracted by ice crystals in the air (just as a normal rainbow is produced by the reflection and refraction of sunlight by raindrops).
What is a Moonbo?
Today, we refer to Moonbows—or “lunar rainbows” as they're sometimes called—as rainbows that occur at night. Like rainbows, a Moonbow forms when light—moonlight rather than sunlight—shines on water droplets.
What is a fire bow rainbow?
“Fire Rainbows” or "rainbow clouds" are neither fire, nor rainbows, but are so called because of their brilliant pastel colors and flame like appearance. Technically they are known as circumhorizontal arc – an ice halo formed by hexagonal, plate-shaped ice crystals in high level cirrus clouds.
Are morning rainbows rare?
We estimate that 5% or less of our visible rainbows occur in the morning.
What color isn’t in the rainbow?
Purple, magenta, and hot pink, as we know, don't occur in the rainbow from a prism because they can only be made as a combination of red and blue light. And those are on opposite sides of the rainbow, nowhere near overlapping.
