This image shows the amazing satellite 10 “Voids Dark Dark” that appeared over an uninhabited volcanic island in the Indian Ocean. Black spots are the result of the cloud’s swirls in the atmosphere, but they are strange in a strange way and greatly compared to most other examples of this phenomenon.
Spinning voids give up Hurd Island – an uninhabited Australian area in the southern Indian Ocean, about 900 miles (1500 km) north of Antarctica. The cloud ground mass area is about 142 square miles (368 square kilometers).
On average, the width of the dark spots is about 8 miles (13 km), which decreases a little whenever they travel, according to what it mentioned. NASA Earth Observatory. They initially move from the island in the northeast (from left to right).
Spinning holes are the result of a phenomenon known as Von Kármán Vortices, which occurs when the prevailing winds coincide with a ground mass, disturbs the air flow and creating a “double row of swirls that alternate its direction of rotation,” according to what he said. National Oceanic and Attrads Administration. It was named the Deodor von Kharsman, an American Hungarian physicist, and was the first to describe this natural phenomenon.
In this case, the swirls are created by Mawson Peak, an active volcano with a length of 9,000 feet (2700 meters) in the heart of Herd Island.

Usually, Von Kármán Vortices creates long paths of clouds that are caught in broken air flows. Cloud flows are usually completely straight It appeared side by side off the Atlantic Coast of Africa in 2015 (See above).
But in this case, it appears that the whirlpool streaming bends approximately 90 degrees in the middle of the road. This change in the direction was likely to be caused by an intermittent explosion of the intense western winds that often blow across the area surrounding Herd Island at speeds of more than 50 miles per hour (80 km/h), known as the “Fifty Fifments”, according to the Earth Observatory.
In most examples on the iPhone Kármán Vortices, the resulting cloud paths can be completely mysterious, and follow the exact differences in invisible air currents, such as examples that have been observed On the island of Guadalobi, Mexico in 2012 and Above the island of Safalbard in 2023.
However, in this picture, mysterious tracks are replaced by a series of concentrated holes, or gaps, inside the clouds. Perhaps this is exceptionally due to exceptionally thick cloud coverage, which can only be disabled in the heart of each department of spinning inside a spiral stream.
Mawson Peak is smaller than most of the peaks that produce Von Kármán regularly, making it a little rare until the cloud swirls appear there. However, Herd Island has produced more traditional vortex currents in the past, such as One offer in November 2015.
