Is extreme Arctic sea ice anomaly in 2007 a key contributor to severe January 2008 snowstorm in China?
Abstract We conduct numerical experiments with an atmospheric general circulation model to answer the question whether the extreme Arctic sea ice anomaly in 2007 contributed to the severe January 2008 snowstorm in China. Results show that the record low Arctic sea ice in September 2007, and follow‐u...
