      Solbrekke, Ida Marie (Master thesis, 2014-06-02)
      During the 25th of December 2011 a strong low pressure system struck Soutwestern Norway. This rapidly evolving system got the name "Dagmar". The aim of this thesis was to find out how the complex topography in Southern ...

    • Topographically Controlled Flow in the Isfjorden Trough and the West Spitsbergen Shelf 

      Vaardal-Lunde, Juni (Master thesis, 2011-11-20)
      A one layer numerical model demonstrates how the Atlantic Water (AW) from the West Spitsbergen Current (WSC) is topographically steered onto the West Spitsbergen Shelf (WSS) with a special emphasise on the Isfjorden Trough. ...

      Research Infrastructures (RIs) are large-scale facilities encompassing instruments, resources, data and services used by the scientific community to conduct high-level research in their respective fields. The development ...

    • Toward an ice-free Barents Sea 

      Onarheim, Ingrid Husøy; Årthun, Marius (Peer reviewed; Journal article, 2017)
      Arctic winter sea ice loss is most pronounced in the Barents Sea. Here we combine observations since 1850 with climate model simulations to examine the recent record low winter Barents Sea ice extent. We find that the ...

    • Towards a better representation of fog microphysics in large-eddy simulations based on an embedded Lagrangian cloud model 

      Schwenkel, Johannes; Maronga, Bjørn (Journal article; Peer reviewed, 2020)
      The development of radiation fog is influenced by multiple physical processes such as radiative cooling and heating, turbulent mixing, and microphysics, which interact on different spatial and temporal scales with one ...
