New Jersey shore had a very spectacular view on Sunday. The shore was full of viewers that felt the unusual phenomenon of Fire Rainbow.
What is it all about?
A lot of guesswork may trick your mind to exactly contemplate on how a Fire Rainbow looks like. In real, the rainbow type actually doesn’t gulp or hurl fire from the sky. Nor it looks like one. In particular, these are neither rainbows nor fire.
More specifically speaking, they go by the name circumhorizontal arc. The arc is a kind of halo, made up of ice. It is formed by plate-shaped, hexagonal ice crystals which are found in high-level cirrus clouds. The halo are considerably large.
As a result, the arc appears to be parallel to the horizon, thus signifying the name. The event is quite peculiar in itself and it was a very blissful encounter to observe the rarest of rare event in the sky.
Even the meteorologists of National Weather Service Jave confirmed the fact. They told media that such kind of circumhorizontal arcs occurs scarcely. If we talk of the past years, the event was one of the “almost never” occuring event.
Physics behind the Fire Rainbow
The science behind the phenomenon seems to be quite interesting. When sunlight hits the ice crystals, present in the higher atmosphere, an appearance comprising of different rainbow colors is formed.
Till now, some similar events have been observed. For instance, the “Sun Dogs” where the sun-rays hits the ice crystals in higher spheres of clouds. They only tend to add up a little color to them.

Both of the phenomenon involves refraction of light by water collecting clusters of clouds. They usually occur at heights of 20,000 feet or higher.
The Fire Rainbows are typical summer events. They are bound on happen only at particular latitudes.
Furthermore, there are some essential conditions required for formation of a Fire Rainbow. The sun should be elevated at 58 degrees or greater. Moreover, sunlight can only enter the crystals at specific angle inclinations.
We hope to have such breathtaking views in future too.
Till then, stay tuned to BlockToro.
