The Role of Atmospheric Waves in Arctic-midlatitude Linkages

Tildelt: kr 0,12 mill.

The Arctic is warming more than twice as fast as the rest of the globe. This warming is accompanied by profound changes in polar regions, including a shrinking sea ice cover, the loss of permafrost, and a moistening of the atmosphere. Coincident with this period of Arctic change, there has been what some researchers suggest is a period of more frequent extreme weather events (e.g., heat waves, severe winters, rainfall extremes). The possibility that Arctic change and midlatitude weather are linked has generated much activity and debate over the past decade. There remain fundamental open questions about how much of the observed Arctic change is a response to rather than a driver of midlatitude variability, and the dynamics underlying the linkages in both directions. The proposed study aims to clarify this by investigating the role of atmospheric wave phenomena in determining the coupling between the Arctic and midlatitudes. Of particular interest are the role of wave mean-flow interactions and wave induced heat transport on the Arctic troposphere, their influence on the coupled response to sea ice loss, and the back effect of sea ice loss in strengthening atmospheric stationary waves.] In addition to addressing these important scientific goals, this work will strengthen partnerships between the Arctic research communities in Norway and Canada, in particular, a collaboration involving the University of Bergen, Bjerknes Centre for Climate Research, and the University of Toronto within an ongoing Klimaforsk-funded project on Dynamics of Arctic-Midlatitude Teleconnections (DynAMiTe).
