This phenomenon is often informally referred to as a ‘fire rainbow’. Ice crystals in the cirrus cloud are acting as floating prisms and refracting the sunlight. To refract the sunlight in a collective manner like this, the ice crystals must be all be aligned horizontally. Thus, this phenomenon is quite rare to see due to the specific alignment of the crystals. It’s especially rare to capture an image like this when you consider the forces that are constantly acting on clouds within the atmosphere. If the wind were to separate the cloud or re-align the crystals, the same effect would not be achieved. The physics represented in this photo creates a captivating art piece with the vibrant unstructured colors as the focus. The cloud structure resembles flames and creates a more interesting shape than a familiar rainbow. This picture was taken near North Fork Mountain in West Virginia by Christa Harbig.

    First Prize – This is a fascinating picture, the way the “fire rainbow” phenomenon was captured is truly amazing. At first I thought it is a “aurora borealis” but after reading the caption I realized that it is a different phenomenon.

    First Prize: I like this a lot because it combines a lot of different elements with fluids and physics as well as the fact that it naturally occurs and someone was lucky enough to get this photo

    First Prize:

    The color and formation of this cloud are very cool and awesome to look at. The fact that this phenomenon is also very rare to see makes this photo even more breathtaking.
