The Arctic has warmed more than twice as fast as the global average since the late twentieth
century, a phenomenon known as Arctic amplification (AA). Recently, there have been …

Accelerated warming in the Arctic, as compared to the rest of the globe, might have profound
impacts on mid-latitude weather. Most studies analyzing Arctic links to mid-latitude weather …

2 Chapter 2 assesses observed large-scale changes in climate system drivers, key climate
indicators and 3 principal modes of variability. Chapter 3 considers model performance and …

Are continuing changes in the Arctic influencing wind patterns and the occurrence of
extreme weather events in northern mid-latitudes? The chaotic nature of atmospheric …

Whether Arctic amplification has contributed to a wavier circulation and more frequent
extreme weather in midlatitudes remains an open question. For two to three decades …

The Arctic is warming and melting at alarming rates. Within the lifetime of a Millennial, the
volume of ice floating on the Arctic Ocean has declined by at least half. The pace of Arctic …

Summer 2010 saw two simultaneous extremes linked by an atmospheric wave train: a
record-breaking heatwave in Russia and severe floods in Pakistan. Here, we study this …

Strong rivers of westerly winds, known as jet streams, are driven primarily by temperature
differences between low and high latitudes as well as the rotation of the Earth. The jet …

Future wintertime atmospheric circulation changes in the Euro–Atlantic (EAT) and Pacific–
North American (PAC) sectors are studied from a weather regimes perspective. The …

The exceptional atmospheric conditions that have accelerated Greenland Ice Sheet mass
loss in recent decades have been repeatedly recognized as a possible dynamical response …
