According to Dr. Cohen, polar vortex splits, like the one that was occurring during the first week of January, favor above-normal temperatures to the north and below-normal temperatures to the south.

These polar vortex stretches are happening more frequently as the world — and especially the Arctic — warms, a 2021 paper published in the journal Science, also co-authored by Cohen, demonstrated.

There were strong polar vortex disruptions and cold outbreaks like this in the 1980s, Cohen said. “I think it’s historic and generational,” Cohen said. “I don’t think it’s unprecedented.
