      Medhaug, Iselin; Langehaug, Helene Reinertsen; Eldevik, Tor; Furevik, Tore; Bentsen, Mats (Peer reviewed; Journal article, 2011-06-25)
      Variability in the Atlantic Meridional Overturning Circulation (AMOC) has been analysed using a 600-year pre-industrial control simulation with the Bergen Climate Model. The typical AMOC variability has amplitudes of 1 ...

    • Mechanisms of decadal North Atlantic climate variability and implications for the recent cold anomaly 

      Årthun, Marius; Wills, Robert C.J.; Johnson, Helen L.; Chafik, Leon; Langehaug, Helene R. (Journal article; Peer reviewed, 2021)
      Decadal sea surface temperature (SST) fluctuations in the North Atlantic Ocean influence climate over adjacent land areas and are a major source of skill in climate predictions. However, the mechanisms underlying decadal ...

    • Mechanisms of Ocean Heat Anomalies in the Norwegian Sea 

      Asbjørnsen, Helene; Årthun, Marius; Skagseth, Øystein; Eldevik, Tor (Peer reviewed; Journal article, 2019-04)
      Ocean heat content in the Norwegian Sea exhibits pronounced variability on interannual to decadal time scales. These ocean heat anomalies are known to influence Arctic sea ice extent, marine ecosystems, and continental ...

    • Mechanisms of offshore solid and liquid freshwater flux from the East Greenland Current 

      Spall, Michael A.; Semper, Stefanie; Våge, Kjetil (Journal article; Peer reviewed, 2024)
      The mechanisms that control the export of freshwater from the East Greenland Current, in both liquid and solid form, are explored using an idealized numerical model and scaling theory. A regional, coupled ocean–sea ice ...

    • Mechanisms of regional winter sea-ice variability in a warming arctic 

      Dörr, Jakob Simon; Årthun, Marius; Eldevik, Tor; Madonna, Erica (Journal article; Peer reviewed, 2021)
      The Arctic winter sea ice cover is in retreat overlaid by large internal variability. Changes to sea ice are driven by exchange of heat, momentum, and freshwater within and between the ocean and the atmosphere. Using a ...

    • The mechanisms that determine the response of the Northern Hemisphere’s stationary waves to North American Ice Sheets 

      Roberts, William H.G.; Li, Camille; Valdes, Paul J. (Peer reviewed; Journal article, 2019-07-01)
      Stationary waves describe the persistent meanders in the west–east flow of the extratropical atmosphere. Here, changes in stationary waves caused by ice sheets over North America are examined and the underlying mechanisms ...
