  • A brief history of climate – the northern seas from the Last Glacial Maximum to global warming 

    Eldevik, Tor; Risebrobakken, Bjørg; Bjune, Anne Elisabeth; Andersson, Carin; Birks, Harry John Betteley; Dokken, Trond Martin; Drange, Helge; Glessmer, Mirjam Sophia; Li, Camille; Nilsen, Jan Even Øie; Otterå, Odd Helge; Richter, Kristin; Skagseth, Øystein (Elsevier, 2014-12)
    The understanding of climate and climate change is fundamentally concerned with two things: a well-defined and sufficiently complete climate record to be explained, for example of observed temperature, and a relevant ...

  • Description and evaluation of the Bergen climate model: ARPEGE coupled with MICOM 

    Furevik, Tore; Bentsen, Mats; Drange, Helge; Kindem, I. K. T.; Kvamstø, Nils Gunnar; Sorteberg, Asgeir (Springer, 2003-07)
    A new coupled atmosphere–ocean–sea ice model has been developed, named the Bergen Climate Model (BCM). It consists of the atmospheric model ARPEGE/IFS, together with a global version of the ocean model MICOM including a ...

  • Effects of simulated natural variability on Arctic temperature 

    Sorteberg, Asgeir; Furevik, Tore; Drange, Helge; Kvamstø, Nils Gunnar (American Geophysical Union, 2005-09-23)
    A five-member ensemble with a coupled atmospheresea ice-ocean model is used to examine the effects of natural variability on climate projections for the Arctic. The individual ensemble members are initialized from a 300 ...

  • Modeling the middle Pliocene climate with a global atmospheric general circulation model 

    Jiang, Dabang; Wang, Huijun; Ding, Zhongli; Lang, Xianmei; Drange, Helge (American Geophysical Union, 2005-07-27)
    A new climate simulation for the middle Pliocene (ca. 3 Ma BP) is performed by a global grid-point atmospheric general circulation model developed at the Institute of Atmospheric Physics (IAP AGCM) with boundary conditions ...

  • The North Atlantic Oscillation and greenhouse-gas forcing 

    Kuzmina, Svetlana I.; Bengtsson, Lennart; Johannessen, Ola M.; Drange, Helge; Bobylev, Leonid P.; Miles, Martin W. (American Geophysical Union, 2005-02-17)
    The results of 12 coupled climate models participating in the Coupled Model Intercomparison Project (CMIP2) are compared together with observational data in order to investigate: 1) How the current generation of climate ...

  • The sensitivity of the present day Atlantic meriodinal overturning circulation to freshwater forcing 

    Otterå, Odd Helge; Drange, Helge; Bentsen, Mats; Kvamstø, Nils Gunnar; Jiang, Dabang (American Geophysical Union, 2003-09-09)
    Mounting evidence indicates that the Atlantic Meridional Overturning Circulation (AMOC) was strongly reduced during cold climate episodes in the past, possible due to freshwater influx from glacial melting. It is also ...

  • Simulated North Atlantic-Nordic Seas water mass exchanges in an isopycnic coordinate OGCM 

    Nilsen, Jan Even Øie; Gao, Yongqi; Drange, Helge; Furevik, Tore; Bentsen, Mats (American Geophysical Union, 2003-05-29)
    The variability in the volume exchanges between the North Atlantic and the Nordic Seas during the last 50 years is investigated using a synoptic forced, global version of the Miami Isopycnic Coordinate Ocean Model (MICOM). ...

  • Simulated variability of the Atlantic meridional overturning circulation 

    Bentsen, Mats; Drange, Helge; Furevik, Tore; Zhou, Tianjun (Springer Verlag, 2004-04-17)
    To examine the multi-annual to decadal scale variability of the Atlantic Meridional Overturning Circulation (AMOC), a four-member ensemble with a daily reanalysis forced, medium-resolution global version of the isopycnic ...
