Linkages Between Arctic Sea Ice Loss and Mid‐Latitude Weather Patterns

Workshop Goals

Rising global average temperatures, and especially intense warming in the northern polar regions, are leading to a rapid loss of the sea ice cap that covers the Arctic ocean. Emerging research may indicate that large losses of Arctic sea ice cover can have dramatic impacts upon weather patterns across the heavily populated northern mid‐latitudes, and that such impacts could increase as ice cover continues to retreat in the coming decades. The workshop will address the following questions:

 

• What do we currently understand about the mechanisms that link declines in Arctic sea ice cover, loss of high‐latitude snow cover, changes in Arctic-region energy fluxes, atmospheric circulation patterns, and the occurrence of extreme weather events?
• What may be the possible implications of more severe loss (and eventually, total loss) of summer Arctic sea ice upon weather patterns at lower latitudes?
• What are the major gaps in our understanding, and what sort of observational and/or modeling efforts are needed to fill those gaps?
• What are the current opportunities and limitations for using Arctic sea ice predictions to assess the risk of temperature/precipitation anomalies and extreme weather events over northern continents? How might these capabilities improve over time?
