Permafrost. The Contemporary Meaning of the Term and its Consequences
Abstract Nowadays the term ‘permafrost’ means the thermal state of the ground, for which the temperature limit value is 0°C remaining for at least two years. It is the effect of the climate where the average annual temperature of the air is -1°C or lower. As a result of air temperature, it does not...
