A bizarre natural phenomenon in the skies of Victoria

Such holes are formed when the water temperature in the clouds is below freezing but the water has not had time to freeze due to the lack of nuclei of crystallization. When ice crystals still formed, it causes a chain reaction in the process of Bergeron. Water droplets around the crystals evaporate, forming a large round hole in the cloud.

Leaky cloud is large circular or elliptical gap that can appear in altocumulus and cirrocumulus clouds. It is believed that this chain reaction causes evaporation of the introduction of large amounts of tiny ice crystals in the cloud layer. Ice crystals can be formed by flying the aircraft with the high pressure behind the wing. Under the influence of the air can instantly cool down and produce a ribbon of ice crystals trailing behind the plane. Such clouds are not unique to any particular geographic area and was photographed in many places.

Because of their rarity and unusual appearance, as well as a very large media coverage, leaky clouds have often been mistaken mistaken for unidentified flying objects.
