A fire rainbow is an extremely rare phenomenon that occurs only when the sun is high, allowing its light to pass through high-altitude clouds which have to contain high amount of ice crystals.'Through years of observation and study, meteorologists have discovered the exact conditions that give rise to a fire rainbow or CHM. For a fire rainbow to form, the Sun is always high up in the sky. Also cirrus clouds have to be present,which have a lot of present ice crystals. It is important that you are at the right location to be able to see the fire rainbow: the position of the Sun faced to you and its altitude decides it. "It is a known fact, that fire rainbows are not visible at positions north of 55 degree North latitude or South of 55 degree south latitude."Fire Rainbows occur mostly around summer solstice.
I love this rainbow, it is so interesting! This is what I have learned about the fire rainbow: It is the rarest atmosphere phenomenon. The clouds have to be 20k feet high, and the sun has to hit the crystals just right, and then a ray of colors go across the sky. I hope this information helps! (:
ReplyDeleteI found out that this rainbow works very similarly to a halo, although it is not a rainbow, because it reflects off of millions of hexagonal ice crystals. I also discovered that the Sun must be shining at exactly 58 degrees above the horizon, or it will not be visible.
