Strange wave cloud in the Indian Ocean

High peaks on volcanic islands of Amsterdam, south of the Indian Ocean, interrupt the flow of air passing through the island, creating clouds of strange waves in the sky.

Amsterdam volcanic island is located in the Indian Ocean, about 3,200km from the mainland. It formed about 300,000 years ago, the highest mountain above the sea level of about 860m. Its height is enough to interrupt the air flow through the island, creating strange clouds in the sky.

According to Live Science, the US space agency Landsat 8 satellite (NASA) captures images of rippling clouds on November 2 and announced on November 28.

When moist air masses pass through the peaks, they are pushed up high, cold and form clouds similar to the peaks of the waves. The lower part of the air is too hot and too low to form a cloud. The result of this process is the appearance of clouds similar to ocean waves, moving several hundred kilometers before merging into other clouds in the northern Indian Ocean.

"Cloud waves" are usually stable and suspended in the sky until there is a different type of weather or air mass. This type of cloud can cause serious disturbance to aircraft.

Climateists think that observing wave clouds can enhance people's understanding of atmospheric conditions above open oceans and small islands.
