What’s the difference between these winters?

The rise in Arctic near-surface air temperatures has been almost twice as large as the global average in recent decades, but cold, snowy winters have been found over mid-latitude land areas since 2007. The Arctic sea ice decline is one of the dramatic indicators of the Arctic warming, and it has both local and remote effects on the other components of the climate system. Several studies suggested a possible link between the Arctic sea ice cover and the weather pattern in the mid-latitude. However, the physical mechanism behind this possible link is still not clear. Here we analyzed the difference between the severe winters during the recent decades in terms of dynamical features. The purpose is to provide better understanding and long term perspective of the drivers of temperature and precipitation variability in the mid-latitude.
