Astonished witnesses saw this week in the skies over Brazil formed an amazing rainbow cloud. This amazing event was able to remove 6 December 2016 Jean Olivier, a resident of Caxias.

While creative minds can think that in this cloud took refuge under the protective cloak of an invisible UFO, or perhaps opened a portal to another world, in fact, it is quite a colorful spectacle has a very prosaic explanation.

According to meteorologists, the white clouds can be painted in spectral colors in the case of the refraction of sunlight in drops of water. The light rays of different wavelengths deviate different, and hence the light of these waves reaches the observer from different directions.

This fully rainbow cloud with bright vivid colors is quite rare. For its formation it is necessary that the water droplets in the cloud were of the same size.
