The article presents a study which examines the thermal dynamics of the active layers at permafrost sites in Svalbard, Norway and in the Tibetan Plateau. The study uses a thermal and hydraulic numerical model with parameters such as heat conduction, heat convection and liquid water flow to analyze the applicability of the model and to quantify the process dominating the sites. It is found out that both sites are dominated by the process of heat conduction.
