На территории криолитозоны и примыкающих регионов наметилась устойчивая тенденция к повышению температуры воздуха, что негативно сказывается на состоянии многолетнемерзлых пород. В связи с этим актуальной становится оценка термической устойчивости многолетнемерзлых пород при современном изменении климата. Предложен геотермический критерий (Gk) для оценки степени влияния изменения климата на температурный режим пород слоя годовых теплооборотов. Gk выражается через безразмерный температурный симплекс t* = (t i /Te) и критерий Фурье. Геотермический критерий предназначен для интерпретации данных, полученных методом термометрии в скважинах. Теоретически обоснована целесообразность использования предложенного критерия на практике, показаны его достаточная универсальность и принципиальная возможность применения для интерпретации данных многолетних натурных наблюдений за формированием температурного режима пород в слое годовых теплооборотов.</p></abstract><trans-abstract xml:lang="en"><p>Since the 1990s, climate variability has significantly increased, revealing various climatic anomalies. A clear trend of rising air temperatures has been observed in the permafrost zone and its adjacent areas, adversely affecting the state of frozen soils. Consequently, it is becoming increasingly important to assess the thermal stability of frozen soils in light of current climate change. As a result, it is becoming increasingly crucial to evaluate the thermal stability of these frozen soils in the context of ongoing climate change. A geothermal criterion (Gk) is suggested to assess the impact of climate change on the temperature regime of frozen soils in areas with seasonally active permafrost. (Gk) is represented through a dimensionless temperature simplex t* = (t i /Te) and the Fourier criterion. It is intended to analyze experimental data from geothermal permafrost research collected via borehole thermometry. The theoretical basis for the practical use of this proposed criterion has been established, showing its broad applicability and significant potential for interpreting data from long-term in-situ observations of temperature regime development in frozen soils within seasonally active permafrost.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>геотермический критерий</kwd><kwd>изменение климата</kwd><kwd>температура грунтов</kwd><kwd>многолетнемерзлые породы</kwd><kwd>деятельный слой</kwd><kwd>слой годовых теплооборотов</kwd><kwd>криолитозона</kwd></kwd-group><kwd-group xml:lang="en"><kwd>geothermal criterion</kwd><kwd>climate change</kwd><kwd>soil temperature</kwd><kwd>permafrost</kwd><kwd>active layer</kwd><kwd>seasonally-active permafrost</kwd><kwd>permafrost zone</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работы выполнены в рамках бюджетного проекта «Тепловое поле и криогенная толща Северо-Востока России.
