The lead author is NSF-funded scientist Judah Cohen, director of seasonal forecasting at Atmospheric and Environmental Research.

Despite a warming planet, winter weather has remained surprisingly resilient across the mid-latitudes of the Northern Hemisphere, and the winter weather headlines have often been about severe cold, heavy snowfalls, and the polar vortex. The unexpected frequency of severe winter weather was not projected by global climate models used to study climate change. It has been challenging, says Cohen, for climate scientists to attribute the recent streak of cold, snowy winters to a particular cause.

Idea - Winter - Weather - United - States

One relatively new idea has been to link severe winter weather across the United States, Europe, and Asia with Arctic amplification, the accelerated warming of the Arctic region at a rate two to three times faster than the rest of the globe. The accelerated Arctic warming was thought to be due mostly to...
