The paper summarizes the experience of studying the effect of modern warming on the thawing depth of sandy and loamy soils in the permafrost zone. The definition of soil cryogenesis as a natural process and facies as the end result of soil cryogenesis as a process is given. The effect of soil cryogenesis facies on stress corrosion cracking of gas pipes of the Gazprom system in cold and warm seasons has been studied. It was found that the facies of soil cryogenesis are interconnected by the process of energy and mass exchange. It is shown that in the annual cycle, each facies formed by soil cryogenesis is the basis for the development of stress corrosion cracking of gas pipelines.

“…Other experimental studies characterized the soil temperature regime under different land cover conditions [ Ballard , ] and in case of climate unsteadiness. In this field, long‐term data series were investigated to detect the effect of climate seasonality on the upper soil layers thermal dynamics, as a proxy to understand the biological response on the agricultural production [ Jacobs et al , ] (grassland in The Netherlands) and the evolution of forest communities [ Khydyakov and Reshotkin , ] (forest‐tundra zone in the Polar Urals). As an application in glacialized environment, Taschner and Ranzi [] monitored and studied the temperature dynamics of a debris covered glacier in order to validate the glacier temperature data collected by means of a remote sensing technique.…”

In dry days the temperature of the upper soil layers presents a characteristic asymmetric periodic-like pattern with a minimum in the morning and a maximum in the afternoon. In view of estimating the conductive heat component of the surface energy balance, at local, basin, and global scales, in this study we use a periodic series solution of the Fourier equation to develop a simple procedure to accurately reconstruct the soil temperature and heat flux profiles. The method is based on weighting and phasing the Fourier harmonics by means of coefficients which do not depend on the soil thermal properties but only depend on the shape of the temperature boundary condition. The proposed coefficients can be regarded to as site independent and with good approximation universal. In order to calibrate and test the procedure, measurements of soil temperature, soil heat flux, and soil water content, collected during the CividatEX Experiment (summer 2012, summer 2013, and spring and summer 2014), in Italy, were used. The method accurately reproduced the temperature observations at three measurement depths within the upper 20 cm soil layer. Once assessed the soil thermal conductivity, the method proved to be effective also in reproducing the measured soil heat flux. The procedure was furthermore validated reconstructing with good results the soil temperature dynamics measured by an independent micrometeorological station in a different environment.

Soil temperature is a sensitive climate indicator. In this paper, we used data from weather stations located in various natural zones of the European part of Russia to demonstrate how the soil temperature responded to modern climate change. The most intensive warming is observed at the beginning of the 21st century. The average annual air temperature for the period 2001–2015 increased compared to the period 1961–1990 by 1.2–1.4°C. The average annual soil temperature has increased in all studied soils and at all depths by 0.5–1.0°C. Soil warming is observed in both warm and cold periods of the year. However, soil temperatures have changed differently in different seasons of the year. The increase in air and soil temperature leads to a shift of the soil-climatic zones to the north.
