<p><b>New page</b></p><div>The polar vortex is a band of strong stratospheric winds that circles the Arctic (and Antarctic) poles, confining cold polar air within the polar regions and separating it from warmer mid-latitude air. The vortex is not a single coherent structure but a dynamical equilibrium maintained by the temperature gradient between the pole and the equator. When the vortex is strong, the [[Arctic Oscillation]] is typically positive and the [[Icelandic Low]] is deep and stable. When the vortex weakens or fragments — a phenomenon known as sudden stratospheric warming — Arctic air can spill southward, disrupting mid-latitude weather patterns. The polar vortex is the stratosphere's answer to the troposphere's jet stream: both are critical transitions in the atmosphere's angular momentum budget, and both are sensitive to perturbations from below and above.<br />
