  • Sorteberg, Asgeir (Journal article, CICERO Senter for klimaforskning, 2009)
    Forskere er avhengig av pålitelige klimaframskrivninger for å kunne si hvilke konsekvenser klimaforandringer får for mennesker og samfunn i framtiden. Men hva kan klimaframskrivninger brukes til og hvordan bør ...
  • Furevik, Tore; Bentsen, Mats; Drange, Helge; Kindem, I. K. T.; Kvamstø, Nils Gunnar; Sorteberg, Asgeir (Journal article; Peer reviewed, 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 ...
  • Azad, Roohollah; Sorteberg, Asgeir (Journal article; Peer reviewed, Royal Meteorological Society and Wiley-Blackwell, 2009)
    In this study, the development of a warm-core and cold-core extratropical cyclone over North Atlantic is examined. The geostrophic relative vorticity tendency used to diagnose the development is calculated utilizing the ...
  • Heikkilä, Ulla Elina; Sandvik, Anne Dagrun; Sorteberg, Asgeir (Peer reviewed; Journal article, Springer, 2010)
    Results from a first-time employment of the WRF regional climate model to climatological simulations in Europe are presented. The ERA-40 reanalysis (resolution 1 ) has been downscaled to a horizontal resolution of 30 ...
  • Lunde, Torleif Markussen; Balkew, Meshesha; Korecha, Diriba; Gebre-Michael, Teshome; Massebo, Fekadu; Sorteberg, Asgeir; Lindtjørn, Bernt (Journal article; Peer reviewed, BioMed Central, 2013-02-25)
    Background: The first part of this study aimed to develop a model for Anopheles gambiae s.l. with separate parametrization schemes for Anopheles gambiae s.s. and Anopheles arabiensis. The characterizations were ...
  • Lunde, Torleif Markussen; Korecha, Diriba; Loha Shumbullo, Eskindir; Sorteberg, Asgeir; Lindtjørn, Bernt (Journal article; Peer reviewed, BioMed Central, 2013-01-23)
    Background: Most of the current biophysical models designed to address the large-scale distribution of malaria assume that transmission of the disease is independent of the vector involved. Another common assumption ...
  • Viste, Ellen Marie; Sorteberg, Asgeir (Journal article, Royal Meteorological Society, 2013-12)
    The main rainy season in Ethiopia occurs during the northern hemisphere summer, when air masses carrying moisture from the Indian Ocean, the Gulf of Guinea, the African continent, the Red Sea, and the Mediterranean Sea, ...
  • Sorteberg, Asgeir; Furevik, Tore; Drange, Helge; Kvamstø, Nils Gunnar (Journal article, 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 ...
  • Elshamy, Mohamed; Seierstad, Ivar Ambjørn; Sorteberg, Asgeir (Journal article; Peer reviewed, Copernicus Publications on behalf of the European Geosciences Union, 2009)
    This study analyses the output of 17 general circulation models (GCMs) included in the 4th IPCC assessment report. Downscaled precipitation and potential (reference crop) evapotranspiration (PET) scenarios for the ...
  • Caidong, Caidong; Sorteberg, Asgeir (Journal article, International Glaciological Society, 2010-06-01)
    Due to a lack of in situ measurements, model-based studies of glacier mass balance in the Tibetan Plateau are very limited. An energy-balance model is applied to analyse the mass-balance sensitivity of Xibu glacier, in the ...
  • Viste, Ellen Marie; Sorteberg, Asgeir (Journal article, Royal Meteorological Society, 2013-01)
    The Ethiopian summer rains occur as air masses of various origins converge above the Ethiopian plateau. In this study, the relative importance of different moisture transport branches has been estimated using the Lagrangian ...
  • Smedsrud, Lars Henrik; Sorteberg, Asgeir; Kloster, Kjell (Journal article; Peer reviewed, American Geophysical Union, 2008)
    The present and future state of the Arctic sea ice cover is explored using new observations and a coupled one dimensional air–sea–ice model. Updated satellite observations of Fram Strait ice-area export show an increase ...
  • Viste, Ellen Marie; Korecha, Diriba; Sorteberg, Asgeir (Journal article, Springer Verlag, 2013-05)
    In 2011, drought in the Horn of Africa again made news headlines. This study aims to quantify the meteorological component of this and other drought episodes in Ethiopia since 1971. A monthly precipitation data set for 14 ...
