A rare natural phenomenon in the skies of Australia — a cloud with a rainbow inside

In the heart of Gippsland lakes local residents were shocked by the cloud with a rainbow inside. According to ABC, this phenomenon is indeed very rare.





These unusual clouds are similar to "gates of heaven", amazing and strange hole in the sky. In the most common hypothesis States that the hole in the clouds caused by falling ice crystals. Ice crystals can form in the higher clouds or in the exhaust gases of the aircraft flown.





If the air has a suitable temperature and moisture content, the falling crystals will absorb water from the air and grow. For this to happen, the water must be so cold that freezing it needs only a suitable surface. Loss of moisture in the air increases the evaporation rate of water droplets in the cloud, and they are scattered, forming a hole.





Became heavier ice crystals continue to fall and form a sparse, clumpy, cloud-like precipitation, which are visible inside and under the hole. Water and ice in these precipitation evaporates before reaching the ground.
