These swirling clouds spotted near the Canary Islands are known as von Kármán vortices. They happen when airflow splits around an object and creates a swirling eddy downstream. In this case, the tall volcanic peaks of the Canary Islands caused the swirling pattern of clouds. Image Description: Satellite image of the coast of Morocco, south of the Canary Islands. Swirls of white, puffy clouds are in the center, surrounded by more circular puffs of clouds that fill almost the whole image. The dark blue ocean peaks through. In the right corner, is the brown coast of Morocco. #Space #NASA #Earth #Clouds」5月1日 0時04分
