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 …

The Arctic region has warmed more than twice as fast as the global average—a
phenomenon known as Arctic amplification. The rapid Arctic warming has contributed to …

With the Arctic rapidly changing, the needs to observe, understand, and model the changes
are essential. To support these needs, an annual cycle of observations of atmospheric …

The possibility that Arctic sea ice loss weakens mid-latitude westerlies, promoting more
severe cold winters, has sparked more than a decade of scientific debate, with apparent …

As climate has warmed over recent years, a new pattern of more frequent and more intense
weather events has unfolded across the globe. Climate models simulate such changes in …

Successive cold winters of severely low temperatures in recent years have had critical social
and economic impacts on the mid-latitude continents in the Northern Hemisphere. Although …

Previous studies have extensively investigated the impact of Arctic sea ice anomalies on the
midlatitude circulation and associated surface climate in winter. However, there is an …

Polar amplification–the phenomenon where external radiative forcing produces a larger
change in surface temperature at high latitudes than the global average–is a key aspect of …

Pronounced changes in the Arctic environment add a new potential driver of anomalous
weather patterns in midlatitudes that affect billions of people. Recent studies of these …
