In fluid dynamics, a vortex (pl.: vortices or vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or...

warmer air can only move along the edge of the polar vortex, but not enter it. Within the vortex, the cold polar air becomes increasingly cold, due to a lack...

2012, Cassini imaged a rotating polar vortex on Titan's southern pole, which the imaging team believe is related to a "polar hood"—an area of dense, high...
