A polar vortex or polar low-pressure area is a vast region with low-strain and freezing air covering both the planet’s poles. The literal meaning of the term vortex is the anti-clockwise movement of air that retains the cold air nearby the poles.
The polar vortex is a large area of low pressure and cold air surrounding both of the Earth’s poles. It ALWAYS exists near the poles, but weakens in summer and strengthens in winter. The term "vortex" refers to the anti-clockwise flow of air that helps keep the colder air near the Poles.
A polar vortex is a large pocket of very cold air, typically the coldest air in the Northern Hemisphere, which sits over the polar region during the winter season. Polar Vortex is a. Cold; Upper tropospheric: sometime extending till the lower levels of stratosphere (At poles, the troposphere extends up to 8-9 km); Circumpolar; Low pressure;
The polar vortex is a large area of low pressure and cold air surrounding both of the Earth’s poles. It was also known as the Polar Pig. The term "vortex" refers to the counterclockwise flow of air that helps keep the colder air near the Poles.
What exactly is a polar vortex? It is described as a whirling cone of low pressure over the poles that is strongest in the winter months due to the increased temperature contrast between the polar regions and the mid-latitudes, such as the US and Europe.

CURRENT AFFAIRS FOR UPSC IAS. “Polar Vortex and its Effects”. Published: 17th Feb, 2020. The mild winters in the northern regions of the hemisphere which are particularly south of the Arctic circle have led to the decrease in the energy consumption by the people.
Formation of polar vortex involves the accumulation of extremely cold air inside a ring of extremely strong westerly winds, also known as the Polar Night Jet. It appears in the upper stratosphere of both the poles every winter season.
The polar vortex is a large, persistent circulation of frigid air located in the stratosphere and typically centred near the Earth’s poles. It is characterized by a strong wind current that circulates from west to east, trapping cold air within the polar regions during the winter months.
