The 1985 North America cold wave [1] was a meteorological event which occurred in January 1985 as a result of the shifting of the polar vortex farther south than is normally seen. [1] Blocked from its normal movement, polar air from the north pushed into nearly every section of the central and eastern half of the United States and Canada ...
A circumpolar vortex, or simply polar vortex, is a large region of cold, ... 1985. Sudden stratospheric warming events are associated with weaker polar vortices.

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] However, this classification is based on the NH SSWs, as no major SSW by this definition has been observed in the SH in winter.
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 ...
The polar vortex is a gigantic, circular area of cold air high up in the atmosphere that typically spins over the North Pole (as its name suggests).
