Early spring typically brings dust storms to northern polar Mars. As the
north polar cap begins to thaw, the temperature difference between the
cold frost region and recently thawed surface results in swirling winds.
The choppy dust clouds of at least three dust storms are visible in this
mosaic of images taken by the Mars Global Surveyor spacecraft in 2002. The
white polar cap is frozen carbon dioxide.
