Presentation Transcript

  1. Arctic Circulation Robert K. Forney

  2. North Atlantic Oscillation (NAO)

  3. The Arctic Oscillation (AO/NAM) Index

  4. Transpolar Drift Stream and Beaufort Gyre

  5. Climate Change • Dramatic decrease in sea ice cover • Beaufort Gyre is weakening—correlated with climate change (freshening) • Changes in arctic circulation impact the rest of the world through oscillations in the jet stream (degree to which cold arctic air enters middle latitudes) • NAM Index has been trending towards neutral in recent time, after a period of positive trend (increased meandering)
