Аннотация:Khibiny Mountains is the area of Russian Arctic with heavely industrialized and densely
populated territories. The region provides significant proportion of areas used for economic
purposes and recreation and thus considered to be a model region to implement approaches of
sustainable development strategy in the light of global changes. In this case observations on
snow cover as one of the main indicator of any change play a significant role.
Khibiny region has a long-standing history of snow cover observations. We analyzed changes of
snow cover properties and corresponding temperature conditions during the period of 30 years.
As of data of Khibiny scientific station (320 m) and mountain station “Centralnaya” of JSC Apatit
(1050 m) general properties of snow cover are stable. The length of the snow cover period, dates
of stable snow cover formation, average snow mass growth, values of maximum snow
accumulation have interannual fluctuations but no significant trend. Within year snow cover
stratigraphy also determine the absence of changes both in metamorphism processes, and in
distribution of temperature and density in the snowpack layers.
The tendency of winter temperature is defined as 0,15ºС per 10 years. Increase of mean annual
temperature is also detected by data of Center of Avalanche Safety JSC “Apatit”. By comparison
of data of winter typification by snowiness and temperature conditions it was determined that for
Khibiny region winters of mean snowiness and moderate temperature are more common.
Changes in climate may become a major factor in accelerating or influencing social and
economic changes and they are needed to be observed in order to understand how these
changes impact the overall capacity of people to adapt to contemporary and possible climate
changes.
