【 摘 要 】

A mathematical model and a numerical method for modeling long-term forecasts of the influence of various climate scenarios on the temperature fields in permafrost soils is developed. This approach allows, in particular, to estimate long-term changes in permafrost, depending on the temperature of air varying, on the precipitations and other factors affecting the degradation of permafrost. Computations are presented for obtaining the temperature in the subsurface layer of the soil, depending on the soil moisture for given values of average monthly temperatures and the intensity of solar radiation.
