• The El Niño effect on Ethiopian summer rainfall 

      Gleixner, Stephanie Nikola; Keenlyside, Noel; Viste, Ellen; Korecha, Diriba (Journal article; Peer reviewed, 2017)
      While El Niño is known to cause failure of Kiremt (boreal summer) rainfall in Ethiopia, the mechanisms are not fully understood. Here we use the ECHAM5 Atmospheric General Circulation Model to investigate the physical link ...
    • Seasonal predictability of Kiremt rainfall in coupled general circulation models 

      Gleixner, Stephanie Nikola; Keenlyside, Noel; Demissie, Teferi Dejene; Counillon, Francois; Wang, Yiguo; Viste, Ellen (Journal article; Peer reviewed, 2017)
      The Ethiopian economy and population is strongly dependent on rainfall. Operational seasonal predictions for the main rainy season (Kiremt, June–September) are based on statistical approaches with Pacific sea surface ...
    • Skillful prediction of northern climate provided by the ocean 

      Årthun, Marius; Eldevik, Tor; Viste, Ellen; Drange, Helge; Furevik, Tore; Johnson, Helen L.; Keenlyside, Noel (Peer reviewed; Journal article, 2017-06-20)
      It is commonly understood that a potential for skillful climate prediction resides in the ocean. It nevertheless remains unresolved to what extent variable ocean heat is imprinted on the atmosphere to realize its predictive ...
    • 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 ...
