Unusual Ocean Cloud Formations Spotted near Canary Islands
Astronauts aboard the International Space Station have captured images of chevron-shaped wave clouds over the southern Indian Ocean, around the Crozet Islands. These clouds are formed due to atmospheric internal waves, which are fluctuations in the air formed when air moves over areas of higher ground, being forced upwards, before being pulled down again by gravity. The Crozet Islands are uninhabited apart from numerous seals, penguins, and sea birds, as well as a few research stations.
