Ship-wave-shaped wave clouds induced by Amsterdam Island, Indian Ocean

Published January 5, 2005
The cloud patterns seen in this image resemble ship waves or “Kelvin ship waves”, which are the V-shaped wakes left by moving objects, such as ships or even ducks. The pattern is not coincidental; wind behaves like a fluid, so when it encounters an obstacle, it must move around it, leaving behind a wake or a visible wave pattern. As the air crested a wave...

Cloud vortices off the Crozet Islands, south Indian Ocean
400 x 300 25 KB - JPEG
Cloud vortices- the interesting patterns seen here- are produced by the flow of air in the atmosphere. Clouds are made up of many small droplets of water or ice crystals, formed around what is called a condensation nucleus, which could be a small particle of dust, ash, or smoke. They reflect all visible wavelengths of sunlight...
