These unusual clouds similar to the "gates to paradise", amazing and strange hole in the sky. The most common hypothesis argues that the hole in the clouds caused by falling ice crystals. Ice crystals can form in the higher clouds or in the exhaust gas flown aircraft.
When the air has a suitable temperature and humidity, the falling crystals will absorb water from the air and grow. In order for this to happen, the water must be so cold that freezing it needs only a suitable surface. Loss of moisture air increases the rate of evaporation of water droplets in the cloud, and they are scattered, forming a hole.
which have become more severe ice crystals form and continue to fall sparse, wispy Similar clouds precipitates that are visible within and under the hole. Water and ice in these precipitation evaporates before reaching the ground.
