If air were visible, it would be a thing of mesmerizing beauty and motion. Air courses in streams and eddies; it rises and falls and flows. This image, taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite on November 9, 2011, offers a rare snapshot of motion in the atmosphere. Currents of air shaped an otherwise uniform layer of marine clouds over the North Sea. Air moving over the ocean flows smoothly over the water because it encounters no obstacles. When the air meets an island, it has to lift up over the land. What goes up must come down, and the air sinks again. The motion sets up a wave pattern that continues for some time until the energy is dissipated.
