Evidence for a wavier jet stream in response to rapid Arctic warming

New metrics and evidence are presented that support a linkage between rapid Arctic warming, relative to Northern hemisphere mid-latitudes, and more frequent high-amplitude (wavy) jet-stream configurations that favor persistent weather patterns. We find robust relationships among seasonal and regional patterns of weaker poleward thickness gradients, weaker zonal upper-level winds, and a more meridional flow direction. These results suggest that as the Arctic continues to warm faster than elsewhere in response to rising greenhouse-gas concentrations, the frequency of extreme weather events caused by persistent jet-stream patterns will increase.

- Persistent Extratropical Regimes and Climate Extremes (2015, background): “Principal among the recent claims is the suggestion of Francis and Vavrus [45] that Arctic warming has already led to weakened westerly winds and hence more slowly moving and amplified wave patterns.”
