    • Moisture transport into the Ethiopian highlands 

      Viste, Ellen Marie; Sorteberg, Asgeir (Journal article, 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 ...
    • Recent and future changes of the Arctic sea-ice cover 

      Smedsrud, Lars Henrik; Sorteberg, Asgeir; Kloster, Kjell (Peer reviewed; Journal article, 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 ...
    • Recent drought and precipitation tendencies in Ethiopia 

      Viste, Ellen Marie; Korecha, Diriba; Sorteberg, Asgeir (Peer reviewed; Journal article, 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 ...
    • Recent wind driven high sea ice area export in the Fram Strait contributes to Arctic sea ice decline 

      Smedsrud, Lars Henrik; Sirevaag, Anders; Kloster, Kjell; Sorteberg, Asgeir; Sandven, Stein (Peer reviewed; Journal article, 2011-10-14)
      Arctic sea ice area has been decreasing for the past two decades. Apart from melting, the southward drift through Fram Strait is the main ice loss mechanism. We present high resolution sea ice drift data across 79° N from ...
    • Snowfall in the Himalayas: An uncertain future from a little-known past 

      Viste, Ellen; Sorteberg, Asgeir (Peer reviewed; Journal article, 2015-06-03)
      Snow and ice provide large amounts of meltwater to the Indus, Ganges and Brahmaputra rivers. This study combines present-day observations and reanalysis data with climate model projections to estimate the amount of snow ...
    • Strengthening malaria and climate research in Ethiopia 

      Lindtjørn, Bernt; Loha, Eskindir; Deressa, Wakgari; Balkew, Meshesha; Gebremichael, Teshome; Sorteberg, Asgeir; Woyessa, Adugna; Animut, Abebe; Diriba, Korecha; Massebo, Fekadu; Viste, Ellen; Lunde, Torleif Markussen; Tesfahun, Dereje (Conference object; Peer reviewed, 2014-09-22)
    • Synoptic Conditions and Moisture Sources Actuating Extreme Precipitation in Nepal 

      Bohlinger, Patrik; Sorteberg, Asgeir; Sodemann, Harald (Peer reviewed; Journal article, 2017-12)
      Despite the vast literature on heavy‐precipitation events in South Asia, synoptic conditions and moisture sources related to extreme precipitation in Nepal have not been addressed systematically. We investigate two types ...
