Atmospheric response in summer linked to recent Arctic sea ice loss

  title={Atmospheric response in summer linked to recent Arctic sea ice loss},
  author={R. E. Petrie and Len C. Shaffrey and Rowan Sutton},
Since 2007 a large decline in Arctic sea ice has been observed. The large-scale atmospheric circulation response to this decline is investigated in ERA-Interim reanalyses and HadGEM3 climate model experiments. In winter, post-2007 observed circulation anomalies over the Arctic, North Atlantic and Eurasia are small compared to interannual variability. In summer, the post-2007 observed circulation is dominated by an anticyclonic anomaly over Greenland which has a large signal-to-noise ratio… CONTINUE READING
