The interface between the cold dry air mass of the pole and the warm moist air mass farther south defines the location of the polar front. The polar front is centered roughly at 60° latitude. A polar vortex strengthens in the winter and weakens in the summer because of its dependence on the temperature difference between the equator and the poles.

Major SSWs occur when the winter polar stratospheric westerlies reverse to easterlies. In minor warmings, the polar temperature gradient reverses but the circulation does not, and in final warmings, the vortex breaks down and remains easterly until the following boreal autumn". [3]
AccuWeather forecasters break down the science behind the polar vortex and how it can influence the weather for locations thousands of miles away. While the name for this phenomenon may sound ...

Meanders of the Northern Hemisphere's jet stream developing around the northern polar vortex (a, b) and finally detaching a "drop" of cold air (c). Orange: warmer masses of air; pink: jet stream; blue: colder masses of air.
The southern pole's cyclone-like storm is roughly the size of Europe. In addition, the southern polar vortex is constantly changing shape but the cause is still unknown. [4] In 1979, NASA's Pioneer Venus observed a double vortex cyclone at the north pole. There haven't been many more close-up observations of the north pole since Pioneer Venus.
