Polar Climate Change as Manifest in Atmospheric Circulation
PURPOSE OF REVIEW: Dynamic manifestations of climate change, i.e. those related to circulation, are less well understood than are thermodynamic, or temperature-related aspects. However, this knowledge gap is narrowing. We review recent progress in understanding the causes of observed changes in pola...
