Computer model simulation showing a split of the polar vortex into two pieces (blue areas), with an unusually mild area (red) in between.
A split in the polar vortex may sound like a complicated weather concept, but it has huge consequences for weather patterns from Canada to Eurasia. The latest split is likely to put Western Europe and much of Eurasia into the deep freeze for the rest of February, and will offer glimpses of hope for snow lovers along the U.S. East Coast.
Figuring out where the coldest air will go and how it will affect worldwide weather patterns for the next several weeks is a key task facing weather forecasters now.
