Photo of the day: Rare ‘fire rainbow’ spotted in Florida sky
A “fire rainbow,” also known as an iridescent cloud, appears in the sky on July 31 over South Florida. The rare phenomenon occurs when clouds containing uniformly sized water droplets diffract light and scatter wavelengths into a colorful ring-like pattern. Iridescent clouds are formed by a different process than rainbows, which occur through refraction and reflection instead of diffraction.
