The term polar vortex can be used to describe two distinct phenomena; the stratospheric polar vortex, and the tropospheric polar vortex. The stratospheric and tropospheric polar vortices both rotate in the direction of the Earth's spin, but they are distinct phenomena that have different sizes, structures, seasonal cycles, and impacts on weather.
In February 2021, a polar vortex descended on the Great Plains, extending as far south as Texas, leaving more than 4.5 million homes and businesses without power and resulting in the deaths of ...
The polar vortex has been “considerably stronger” than usual this year, according to Laura Ciasto, a meteorologist with NOAA’s Climate Prediction Center, which should keep record-breaking ...

Prior to the events of January 2014, several studies on the connection between extreme weather and the polar vortex were published suggesting a link between climate change and increasingly extreme temperatures experienced by mid-latitudes (e.g., central North America). [89]
When the polar vortex is strong, the polar jet stream locks bitterly cold, dry air in place over the Arctic. When strong, these winds essentially act as an unscalable wall that frigid air cannot ...
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]
The polar vortex is a whirling cone of low pressure over the poles that's strongest in the winter months due to the increased temperature contrast between the polar regions and the mid-latitudes ...
