Snow cover evolution in the high arctic, nordenskiöld land (Spitsbergen, Svalbard)

Abstract:

In the present work the characteristics and evolution of the snow cover in Spitsbergen, 75°N are studied. The main factors determining the snow cover characteristics are the topography and wind bkp_redistribution. Snow drift by wind and freeze processes determine the transformation and structure of the snow cover. The snow cover is simpler on the platforms and valley bottom and more complex on slopes. The spring transformation of snow is quick, and due to the permafrost presence it disappearances slowly. During spring and summer the snow cover is quickly unstabilized and the higher number of snow avalanches are generated. In this period the most efficient geomorphic processes are produced.
