Model computations on the climate change effects on snow cover, soil moisture and soil frost in the boreal conditions over Finland
This study considered how climate change affects the accumulation of snow, the soil moisture and soil frost at sites without tree cover in boreal conditions in Finland (60°â70°N). An increase of 4.5 °C in annual mean temperature and 20 % in annual precipitation were assumed for Finland by the ye...
