    • Avalanche characterization for regional forecasting 

      Kristensen, Krister; Kronholm, Kalle; Bjørdal, Nils H. (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)
      In the Sunnmøre and Romsdal road districts in Western Norway, the local road authorities have compiled a register of more than 300 sites where avalanches encounter principal roads in the area. The area covered is about 5 ...

    • An avalanche forecasting program based on a modified nearest neighbour method. 

      Kristensen, Krister; Larsson, Christer (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 1994)
      As a part of an avalanche forecasting system, a modified nearest neighbour program is described. The system is intended to be used with forecast values for most ofthe parameters. The modifications consist of 1) the use of ...

    • Could retrieval of snow layer formation by optical satellite remote sensing help avalanche forecasting? Presentation of first results 

      Solberg, Rune; Frauenfelder, Regula; Koren, Hans; Kronholm, Kalle (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2008)
      Of special interest within the field of avalanche research and avalanche warning are properties related to snow grain type and snow grain size at the surface. In continental and intermountain avalanche climates weak layers ...

    • Forcasting snow avalanche days from meteorological data using classification trees; Grasdalen, Western Norway 

      Kronholm, Kalle; Vikhamar-Schuler, Dagrun; Jaedicke, Christian; Isaksen, Ketil; Sorteberg, Asgeir; Kristensen, Krister (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2006)
      Avalanches pose one of the most serious problems to infrastructure and people in the mountains in Norway. Processes leading to avalanche release are deterministic but the time and place of avalanche release is notoriously ...

    • Temporal changes in the spatial variability of shear strength and stability. 

      Logan, Spencer; Birkeland, Karl W.; Kronholm, Kalle; Hansen, Kathy (The International Snow Science Workshop (ISSW) Proceedings;, Chapter, 2006)
      Avalanche forecasting involves the prediction of spatial and temporal variability of the snowpack. To predict avalanches with more accuracy it is important to determine whether the snowpack is becoming more spatially ...
