  • Snow cover a frequent phenomenon in Slovenia and even in the lowlands of the interior regions, it can last for several weeks. The properties of snow and winter weather after the snow cover has formed, determine the load of snow upon houses, trees
  • and other objects. Water accumulation of snow cover (WASC) gives us the amount of water in snow and therefore also the weight of snow. Deep snow cover can soak its own melting water from the surface, so WASC does not decrease as fast as one would conclude

  • The influence of micro-climate, snow cover, and soil moisture on ecosystem functioning in high mountains
  • Climatic change ; Ecosystem ; High mountain ; Microclimate ; Mountain ; Norway ; Snow ; Snow cover ; Soil moisture ; Temperature
  • The dynamics of water and energy fluxes in the high mountains of central Norway was studied along micro-spatial topographic gradients in different altitudes and regions of the Scandes. Landscape ecological processes like snow accumulation during
  • winter, snow melting, evaporation, percolation, soil moisture variability and temperature variations were quantified. Combining spatio-temporal data on physical environment functioning and vegetation patterns resulted in a process-oriented

  • The AA. provide a summary of the current state of knowledge pertaining to the geophysical, thermodynamic and dielectric properties of snow on sea ice. They first give a detailed description of snow thermophysical properties such as thermal
  • conductivity, diffusivity and specific heat and how snow geophysical /electrical properties and the seasonal surface energy balance affect them. The AA. also review the different microwave emission and scattering mechanisms associated with snow-covered first
  • -year sea ice. Finally, they discuss the annual evolution of the Arctic system through snow thermodynamic and aeolian processes, with linkages to microwave remote sensing.

  • Permafrost aggradation caused by tephra accumulation over snow-covered surfaces : examples from the Hekla-2000 eruption in Iceland
  • The aim of this paper is an analysis of tephra accumulation on a pre-eruption winter snow cover and its influence on permafrost aggradation. Based on multi-annual field observations at the Hekla volcano, southern Iceland, a conceptual model
  • concerning the relationship between winter-fallen tephra and buried snow preservation is suggested. Furthermore, the relation of volcanic eruptions and potential preservation of buried snow in permafrost conditions on a global scale is discussed.
