Meet the jet stream. It’s a river of air that screams around the planet at 200 miles per hour. Normally, it keeps cold air trapped up near the North Pole.
But sometimes, this river gets wavy. Like a noodle. When it dips south, it drags Arctic air right over your neighborhood.
That’s why you’re shivering. The jet stream just burped a polar vortex down on you. Yes, burped—that’s the technical term in meteorology (okay, not really, but it should be).
Polar Vortex: Not a Band, But It Should Be
The polar vortex sounds like a 90s metal band. It’s actually a giant swirl of freezing air that normally lives above Canada. Think of it as the frozen heart of winter.
When the jet stream gets wobbly, that vortex can break off. It decides to visit you. Like an uninvited relative who brings only cold drafts and no snacks.
Fun fact: The polar vortex isn’t new. It’s been around forever. We just gave it a scary name so you pay attention. Marketing works—even in weather.
