The Weird and Beautiful World of Fluid Dynamics

As air flows over and around objects in its path, spiraling eddies, known as Von Karman vortices, may form. The vortices in this image were created when prevailing winds sweeping east across the northern Pacific Ocean ecountered Alaska's Aleutian Islands.

there are even clouds! Each of these swirling clouds is a result of a meteorological phenomenon known as a Karman vortex. These vortices appeared over Alexander Selkirk Island in the southern Pacific Ocean. Rising precipitously from the surrounding waters, the highest point on the island is nearly a mile (1.6 km) above sea level. As wind-driven clouds encounter this obstacle, they flow around it to form these large, spinning eddies.

Von Kármán Vortices, Southern Pacific Ocean, 1999 Swirling clouds line up in a formation known as a von Kármán street. They appear when wind-driven clouds encounter an obstacle, in this instance Alexander Selkirk Island in the southern Pacific Ocean.
