Get better at science with Brilliant: If you live in the northern hemisphere at the moment, you may be asking “why is it so cold?“, and you might have heard of something called the “stratospheric polar vortex“ splitting apart in something called a “sudden stratospheric warming“. Confused? In this video I explain what's going on, using research from my PhD on the subject! There's a lot of extra material that I had to cut from this video due to running time. If you have any extra questions, please feel free to ask in the comments - this subject has been my life for four years so I probably know the answer! Note: I am using the word 'storm' in an unconventional (colloquial) way - no one would normally refer to the polar vortex as a storm, as that normally refers to extreme meteorology affecting the surface. However, I think you could argue that the word is actually appropriate here! For visualisations: (have a play!)
