Understanding the Polar Vortex and Its Role in Dangerous Cold Weather
The polar vortex is a key player in extreme winter weather, causing dangerously low temperatures across North America and beyond

Toronto: So, the polar vortex, huh? It’s this big weather pattern that keeps the coldest air locked up in the Arctic. When it gets weak, that frigid air can spill down south, and boy, does it get chilly!
This isn’t some new phenomenon. The term has been around for ages, but it really caught on in the early 2010s. Remember that brutal cold snap in 2014? Toronto was freezing, with temps dropping below -15°C for weeks. Calgary wasn’t much better, hitting -20°C!
The polar vortex is like a big wall of wind up high in the atmosphere. It keeps the cold air contained, but when it weakens, that’s when we feel the bite. It’s not a storm, but it can bring some serious cold.
When the vortex is strong, the cold stays up north. But if it weakens, we can get these cold snaps that last a few days or even longer. Sometimes, it’s just a quick dip in temperatures, but other times, it can linger and really chill things down.
These cold snaps can be tricky. There are quick ones that come and go, and then there are those stubborn ones that hang around. They can send Arctic air sweeping across Canada, even reaching places like Vancouver!
So, keep an eye on the weather. The polar vortex might just be the reason you need to bundle up this winter!
