| Abstract: | A quantitative assessment of the cryosolic-thermal regime of soils and earth materials in the Angara region was made to identify its type, and several subtypes. The processes of seasonal freezing and thawing were used as the classification attribute of the type. Procedural techniques are suggested for analyzing the structure of the time series of temperature of soils and earth materials, and its response to current climate change is assessed. The cartographic model has been constructed on the basis of the characteristics obtained for the long-term temperature dynamics, the directedness, and for the magnitude of trends. |
