|What is a polar vortex?|
However, there are infographics that make me exclaim: "That's it. That's all I need to know!" The latest one I've seen comes from The Washington Post, and it explains what a polar vortex is. Would I like to see more? Sure. I'd like to be able to explore those maps, to zoom in to the areas that were affected by the vortex, etc. But those are minor grievances. The fact is that the step-by-step explanation is as simple and clear as it gets: No realistic 3D or gratuitous lighting and shading effects, no fancy animations and transitions. Just the story, tightly edited.
