1 -90 0 8000000 Polar Vortex The polar vortex is an atmospheric regional event that isolates polar air from the air at temperate latitudes, producing conditions favorable for wintertime polar ozone depletion and other chemical perturbations. The location, size, and shape of the polar vortex is derived from potential vorticity (PV) data. Animation (1024x512) This animation shows a flat map version of the southern polar vortex at 550 degrees Kelvin during part of 2004. 1 0 2004-08-13 2004-11-15T23:59:59Z 2004-08-13 1 1 2004-08-13
