A new study in the journal Nature Communications by researchers from Geophysical Institute, University of Bergen and Bjerknes Centre for Climate Research, Norway, and University of Oxford, UK, demonstrates that there is a clear potential for practical and useful predictions of northwestern European and Arctic climate based on the state of the ocean.
"We particularly predict that Norwegian air temperature will decrease over the coming years, although staying above the long-term (1981–2010) average. Winter Arctic sea ice extent will remain low but with a general increase toward 2020", lead author Marius Årthun says.

Time lag of 7-10 years
Time series of observed sea surface temperature along the North Atlantic Current and its poleward extension, the Norwegian Atlantic Current, show that anomalies progress poleward from the subpolar North Atlantic to the Nordic Seas with a time lag of 7-10 years. Higher Nordic Seas temperatures are furthermore associated with higher surface air temperatures and precipitation over Norway, and a reduced Arctic winter sea ice cover.
