  • The computer model PERMEBAL (which stands for Permafrost and Energy Balance) simulates the persistence of snow cover and daily ground surface temperatures of snow-free gridpoints. It was developed for high-mountain conditions. The model describes
  • different vertical energy fluxes at the surface. Special emphasis is given to simulation of snow-cover development (snow fall, snow redistribution, snowmelt). The aim is to model ground thermal conditions and thus permafrost distribution. The model

  • The AA. conducted an examination of the spatial and temporal relationships and correlations between snow cover and wildfire from 1986 through 1996 in the 11 western states of the United States. Snow-cover and wildfire data were aggregated
  • and normalized for each state, as well as for the entire western region. No strong correlation was found for the entire western United States, nor did state aggregations show signs of consistent yearly correlation between measures of snow cover and wildfire
  • . Nevertheless, a few states experienced above-average acreage burned totals following winters with above-average snow cover.

  • through seasonal surface transfer functions and subsurface thermal properties. The temperature of permafrost (TTOP) results from the interplay between the air temperature, the nival (snow) offset and the thermal offset. These offset values vary
  • systematically and geographically with freezing and thawing indices, snow cover conditions and ground thermal properties.
