Island Wakes
Canary Islands, Atlantic Ocean
July 2002
When winds blow cloud formations around an obstacle such as an island, large wakes and swirls, called "vortices," are formed in the atmosphere. Here, stratocumulus cloud vortices spin near the Canary Islands in the Atlantic Ocean, about 70 miles off the African coast. MODIS sensors can map cloud concentrations around the globe.
