If you live in the United States, you probably have heard the term polar vortex by now. People have been using the term to describe the bitterly cold temperatures affecting the eastern two-thirds of the country. But the term polar vortex is a meteorological term that means a specific phenomenon. In other words, it’s more than a hashtag along the lines of snowmageddon. The Washington Post explains what the polar vortex is.
The Post explains the polar vortex
My caveat for this piece is that from my understanding, it’s not entirely correct. Or perhaps not detailed enough. In brief, we turn to the National Weather Service out of New York for a more technically correct, but more poorly designed graphic.
National Weather Service explanation
Poor type, poor colours, poor hierarchy. Those are abundantly clear, but the important part is that the NWS wants to correct many of the popular misconceptions. Somewhere between the well-intended but less-than-entirely-clear Post piece and the accurate-but-also-unclear National Weather Service piece is an opportunity to explain the concept to the public.
