Использовалась нестационарная модель многолетней мерзлоты CryoGrid с новым блоком, описывающим водный и тепловой режимы многолетнемерзлых болот. Для расчетов использовались данные реанализа ERA5 суточной дискретности по 8 метеорологическим параметрам. Модель была верифицирована на данных комплексных экспедиционных исследований Государственного гидрологического института, проводившихся в 1971–1992 гг. на 10 болотных стационарах южной и северной криолитозоны Западной Сибири. Расчеты указывают на значительные изменения состояния многолетнемерзлых болот за 50 лет. Их скорость увеличилась в последние 25 лет и составила в среднем по зонам распространения полигональных и бугристых болот, соответственно, 1,35 и 1,10 °С/10 лет для температуры торфяной залежи на глубине 20 см; 9,6 и 5,2 см/10 лет для мощности сезонно-талого слоя и –1,1 и –2,9 см/10 лет для уровня надмерзлотных вод.</p></abstract><trans-abstract xml:lang="en"><p>Two types of frozen bogs, palsa mires and polygonal marshes, occupy up to 30 % of the permafrost terrain in West Siberia. Palsa mires span the territory from the Arctic Circle down to approximately 62° N in continuous, discontinuous and sporadic permafrost zones; polygonal marshes are located northward from the Arctic Circle. The hydro-thermal regime of permafrost bogs is characterized by three key parameters, namely, soil temperature, active-layer thickness (ALT), and soil water table depth. We used the CryoGrid community model with daily ERA-5 reanalysis meteorological data to study changes in these parameters in the period 1971–2024. The model was calibrated using an extensive historical data set of the State Hydrological Institute for 10 permafrost bog plots, which was built up in the course of the field expeditions in West Siberia in the 1971–1992 period. The calibrated CryoGrid model demonstrated reasonably good performance in reproducing observed parameters of the hydro-thermal regime of permafrost bogs in a variety of climatic, bio-physiographic and permafrost conditions. The mean square errors of the calculated parameters for polygonal marshes/palsa mires were the following:   ALT error (3.8 ÷ 5.6 cm)/(5.2 ÷ 5.9 cm); soil temperature error (1.2 ÷ 1.5 °C)/(0.8 ÷ 1.3 °C) and soil water level error (6.8 ÷ 10.5 cm)/(7.9 ÷ 9.7 cm). The modelling results suggest that changes in the hydro-thermal regime of permafrost bogs have increased in the past 25 years. Calculated over the 2000–2024 period trends, averaged over the areas occupied by polygonal marshes and palsas, were, correspondingly, as follows: 1.35 and 1.10 °С/10y for soil temperature at 20 cm depth; 9.6 and 5.2 cm/10y for ALT; –1,1 and –2,9 cm/10y for soil water levels.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многолетнемерзлые болота</kwd><kwd>Западная Сибирь</kwd><kwd>модель CryoGrid</kwd><kwd>водно-тепловой режим</kwd><kwd>торфяные залежи</kwd></kwd-group><kwd-group xml:lang="en"><kwd>permafrost bogs</kwd><kwd>West Siberia</kwd><kwd>CryoGrid model</kwd><kwd>hydro-thermal regime</kwd><kwd>peatland</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Финансирование работы осуществлялось в рамках темы 1.5 государственной программы «Научно-технологическое развитие Российской Федерации».</funding-statement><funding-statement xml:lang="en">The work was funded within the framework of topic 1.5 of the State Program “Scientific and Technological Development of the Russian Federation”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Вомперский С.Э., Сирин А.А., Цыганова О.П., Валяева Н.А., Майков Д.А.
