7、火彩虹(Fire Rainbows)
火彩虹(Fire Rainbows)
环弧状火彩虹出现概率非常低，它是太阳和一些云层在正确的时间和位置出现罕见的交汇，云层中的冰晶体反应光线形成不同可见波谱光，由于该现象十分罕见，人们拍摄的机会也很难得。
A circumhorizontal fire rainbow arc occurs at a rare confluence of right time and right place for the sun and certain clouds. Crystals within the clouds refract light into the various visible waves of the spectrum but only if they are arrayed correctly relative to the ground below. Due to the rarity with which all of these events happen in conjunction with one another, there are relatively few remarkable photos of this phenomena.
