    • Fine scale distribution of precipitation in the Voss area 

      Pontoppidan, Marie Louise Nielsen (The University of Bergen, 2015-06-05)
      The precipitation in Western Norway is strongly affected by its position in the mid latitude conveyor belt of synoptic systems. When the warm and moist air impinges on the complex mountainous terrain, large variabilities ...
