Abstract
Results of the study of the regularities of new formation of frozen ground near the southern boundary of permafrost against the background of a positive climate trend are presented. Criteria for the potential formation of permafrost in response to climate warming are established. Results of modeling and quantitative assessment of the newly formed permafrost caused by transformation of landforms during thawing of frozen ground are given with respect to soil drainage and warming effect of the snow cover.
