Original Note:
Sudden stratospheric warmings, which is what this animation shows, are a natural phenomenon which have occurred in about 50% of Arctic winters since the 1950s. It's also unclear how the frequency or strength of the stratospheric polar vortex might change due to climate change. https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2022JD036992
