Long-Term Temperature Regime of the Northeast European Permafrost Region During Contemporary Climate Warming

摘要

This paper discusses the data of 30- and 40-year-long permafrost monitoring on the pediment plain and the glacial-marine plain, respectively. The sites are located in the Vorkuta hydrogeological permafrost area within the zone of discontinuous warm permafrost. The variability of mean decadal changes in permafrost and talik temperatures at depths of 10-15 m depends on meteorological, permafrost, hydrogeological, and other factors. The variability of amplitudes of these changes over the entire monitoring period is examined. Mean annual values of ground warming for permafrost and taliks under various natural conditions are estimated for the entire monitoring period.
