Two cyclones are seen, after forming in tandem in November ۲۰۰۶. The Moderate Resolution Imaging Spectroradiometer (MODIS) onboard NASA's Terra satellite took this picture of the two cyclones south of Iceland on November ۲۰ (South is up in image). (NASA/Jesse Allen, Earth Observatory)
Even the most snow-covered place on Earth has patches of snow-free ground. In Antarctica, a series of parallel valleys lie between the Ross Sea and the East Antarctic Ice Sheet. Known as the Dry Valleys, they are swept free of snow by nearly relentless katabatic winds - cold, dry air that rolls downhill toward the sea from the high altitudes of the ice sheet. The Dry Valleys harbor a collection of glaciers and ice-covered lakes. This false-color image was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite on November ۲۹, ۲۰۰۰.
