Анализ сезонных вариаций температуры снега на различных глубинах с помощью модели теплопереноса позволил установить зависимость относительной теплопроводности снега от его пористости для этого района Антарктиды. Такой же анализ выполнен по аналогичным данным, полученным на станции Купол Фуджи в 1995–1997 гг. Установлено, что теплопроводность слоев снега, имеющих одинаковую плотность, заметно меньше на Куполе Фуджи, чем на станции Восток, что свидетельствует о различии структурных свойств снега, влияющих на его теплофизические свойства, в указанных пунктах. Показано, что кондуктивная теплопроводность является основным механизмом переноса тепла, определяющим распределение температуры в снежной толще на высокогорном антарктическом плато. Полученные параметры модели теплопереноса могут быть использованы при реконструкции изменений температуры поверхности антарктического ледникового покрова по данным многолетних измерений температуры верхнего 100-метрового слоя ледника.</p></abstract><trans-abstract xml:lang="en"><p>The data on snow the temperature which was monitored to a depth of 10 m in the vicinity of Vostok Station by the TAUTO autonomous system in 2010–2017 are presented. By analyzing seasonal temperature variations at different depth with the aid of a heat-transfer model we have inferred a relationship between relative thermal conductivity of snow and its porosity at this site. The same approach was also applied to analyze similar data obtained at Dome Fuji station in 1995–1997. It was found that the thermal conductivity of snow layers with identical density is noticeably lower at Dome Fuji than at Vostok, which point to a difference in structural characteristics of snow that determine its thermophysical properties. We demonstrate that the conduction is the dominant heat-transport mechanism which controls the temperature distribution in snow pack on the Antarctic plateau. The obtained parameters of the heat-transfer model can be used for reconstructing the past surface temperature variations from the long-term temperature measurements in the upper 100 m thick layer of the ice sheet.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Антарктида</kwd><kwd>метаморфизм снега</kwd><kwd>модель теплопереноса</kwd><kwd>снег</kwd><kwd>температура</kwd><kwd>теплофизические свойства</kwd><kwd>численные эксперименты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Antarctica</kwd><kwd>heat-transfer model</kwd><kwd>numerical experiments</kwd><kwd>snow</kwd><kwd>snow metamorphism</kwd><kwd>temperature measurements</kwd><kwd>thermophysical properties</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского фонда фундаментальных исследований, грант 18–55–16002 НЦНИЛ_а.
