Arctic/Atlantic exchanges via the Subpolar Gyre
Langehaug, Helene Reinertsen; Medhaug, Iselin; Eldevik, Tor; Otterå, Odd Helge (Peer reviewed; Journal article, 2012)In the present study we investigate the decadal variability in the strength and shape of the Subpolar Gyre (SPG) in a 600-year pre-industrial simulation using the Bergen Climate Model. The atmospheric influence on the SPG ... -
Changes in the properties and distribution of the intermediate and deep waters in the Fram Strait
Langehaug, Helene Reinertsen; Falck, Eva (Peer reviewed; Journal article, 2012-04)The Fram Strait is the only deep connection between the Arctic Ocean and the Nordic Seas (Greenland, Iceland, and Norwegian Seas), with a sill depth of approximately 2600 m. Consequently, observations from this area reflect ... -
Circulation and transformation of Atlantic and Arctic water masses in climate models
Langehaug, Helene Reinertsen (Doctoral thesis, 2011-12-09)Ocean heat transport and associated heat loss to the atmosphere contributes significantly to the anomalously mild climate of northwestern Europe and its variability. In this thesis, the circulation and transformation of ... -
Mechanisms for decadal scale variability in a simulated Atlantic Meridional Overturning Circulation
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 ... -
Using simulations of the last millennium to understand climate variability seen in palaeo-observations: Similar variation of Iceland-Scotland overflow strength and Atlantic Multidecadal Oscillation
Lohmann, Katja; Mignot, Juliette; Langehaug, Helene Reinertsen; Jungclaus, Johann H.; Matei, Daniela; Otterå, Odd Helge; Gao, Yongqi; Mjell, Tor Lien; Ninnemann, Ulysses Silas; Kleiven, Helga Flesche (Peer reviewed; Journal article, 2015-02-10)A recent palaeo-reconstruction of the strength of the Iceland–Scotland overflow during the last 600 years suggests that its low-frequency variability exhibits strong similarity with palaeo-reconstructions of the Atlantic ... -
Water mass transformation and the North Atlantic Current in three multi-century climate model simulations
Langehaug, Helene Reinertsen; Rhines, Peter B.; Eldevik, Tor; Mignot, Juliette; Lohmann, Katja (Journal article, 2012-11)The warm and saline Subtropical Water carried by the North Atlantic Current undergoes substantial transformation on its way to higher latitudes as heat is released from ocean to atmosphere. The geographical distribution ...
