[HTML][HTML] Warm Arctic episodes linked with increased frequency of extreme winter weather in the United States
J Cohen, K Pfeiffer, JA Francis - Nature communications, 2018 - nature.com
Recent boreal winters have exhibited a large-scale seesaw temperature pattern
characterized by an unusually warm Arctic and cold continents. Whether there is any
physical link between Arctic variability and Northern Hemisphere (NH) extreme weather is
an active area of research. Using a recently developed index of severe winter weather, we
show that the occurrence of severe winter weather in the United States is significantly
related to anomalies in pan-Arctic geopotential heights and temperatures. As the Arctic …
