The term “Polar Vortex” was thrown around a lot last year, in reference to the persistent mass of very cold air that enveloped much of southern Canada and the US. As you will remember, Rush Limbaugh accused climate scientists and librul meteorologists of making up the polar vortex to scare everyone into thinking climate change is real. You may also remember Al Roker pointing out on national TV and on Twitter that the term “polar vortex” has been in meteorology textbooks for decades.
This year, with a new wave of cold air arriving unseasonably in the upper middle part of the US, the term is being used again. I was amused to see the term being used on accuweather such that it was placed on each of several graphics used to show that this year’s cold snap is not actually the polar vortex, unlike last year.
