Arctic/Mid-Latitude Linkages: New Evidence, Mechanisms, Metrics, and
Emerging Questions<br>

<b>Abstract</b><br>
In this presentation, I will build on analysis presented in Francis
and Vavrus (GRL, 2012) in which mechanisms were proposed and
demonstrated that link enhanced warming in the Arctic (Arctic
amplification) during recent decades with changes in mid-latitude
weather patterns. A flurry of new studies provide additional
evidence for linkages that differ by season and region, and new
metrics suggest that Arctic amplification is leading to more
amplified jet-stream patterns and blocking. Prolonged weather
conditions are often associated with extreme weather, such as
droughts, cold spells, heat waves, and some flooding events, which
have become more frequent in recent years. Recent progress is
illuminating but also leads to new questions and unknowns, which I
will discuss.<br>
