What is the polar vortex and how does it influence the weather? Go to https://journals.ametsoc.org/doi/pdf/10.1175/BAMS-D-15-002-1 … the polar vortex is a term that has eagerly been taken up by the media – and by numerous people who know little about climate. Is it fake news? The term is used in the literature to explain two different features of atmospheric circulation – one in the troposphere and the other, in the stratosphere. This has caused what we might call a little confusion – and hot air. The real cause of confusion however is that the media presents the polar vortex as an unusual event, coincident with the idea of climate change (a changing climate that actually is always changing). The polar vortex is, as a a fact, is neither unusual or extreme. They are simply basic features of Earth's climate system.

The article goes on to clarify what they are and how they work. Get clued up on this subject and don't be fooled by Project Fear.
