Шпицберген. В исследовании получены экстремальные значения ПТВ, проведена оценка связи экстремальной ПТВ в Баренцбурге с ПТВ в пунктах Лонгйир, Хорнсунн, Ис-фьорд Радио, Пирамида, Ню-Олесунн. Выделены и рассмотрены экстремально холодные и теплые периоды года с октября по май за ряд наблюдений с 1912 по 2022 г. Проанализированы особенности атмосферной циркуляции на приземном уровне, уровнях высот геопотенциальных поверхностей 500 гПа и 700 гПа, аномалии ПТВ, приводятся результаты сопоставления индексов атмосферной циркуляции NAO и AO при формировании экстремальных ПТВ. Полученные оценки макропроцессов могут применяться при составлении долгосрочных прогнозов по северной полярной области и детализации их по району Шпицбергена.</p></abstract><trans-abstract xml:lang="en"><p>The article presents research findings of meteorological conditions during the formation of extreme surface air temperature (SAT) in the cold period from October to May in the Barentsburg area, the Spitzbergen (Svalbard) archipelago. Six extremely cold periods and six extremely warm periods for the weather sequence from 1912 to 2022 are considered. Correlation coefficients of extreme SAT in Barentsburg with extreme SAT in the points of Longyearbyen, Hornsund, Isfjord Radio, Pyramiden, Nu-Alesund, located in the west of Spitzbergen (Svalbard), were calculated. Also, characteristics of atmospheric circulation at the surface level, the level of the geopotential surface 500 hPa and 700 hPa and air temperature anomalies are analyzed, the results of comparing atmospheric circulation indices NAO and AO in the formation of extreme SAT are presented. Characteristic localizations of the polar vortex were found during the formation of negative and positive anomalies of SAT. For cold periods with extremely low temperatures, the localization of the polar vortex in the northeast of the Kara Sea and Severnaya Zemlya archipelago is observed. At the surface level the baric trough from the Atlantic depression is shifted to the coast of Scandinavia and the southern part of the Barents Sea. The Svalbard region is under the influence of the periphery of the anticyclonic field over the Arctic basin, Greenland, over the western Arctic Seas, conditions are formed for the deviation of SAT by 3–4 degrees below normal. In the case of extremely high SAT, the polar vortex is shifted to the eastern part of the Canadian Arctic Archipelago and the Baffin Sea. At the surface level, the baric trough from the Icelandic depression develops over the Greenland, Norwegian and Barents Seas, which leads to the moving of warm air masses from the Atlantic to polar latitudes and the formation of average SAT in the Spitzbergen (Svalbard) region above long-term values by 1–2 degrees. The estimates of macroprocesses obtained can be used for preparing long-term forecasts for the northern polar region and detailing them for the Spitzbergen (Svalbard) region.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>атмосферная циркуляция</kwd><kwd>Западная Арктика</kwd><kwd>синоптические процессы</kwd><kwd>температура воздуха</kwd><kwd>циркумполярный вихрь</kwd><kwd>Шпицберген</kwd></kwd-group><kwd-group xml:lang="en"><kwd>air temperature</kwd><kwd>atmospheric circulation</kwd><kwd>polar vortex</kwd><kwd>Svalbard</kwd><kwd>synoptic processes</kwd><kwd>Western Arctic</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено в рамках проекта 5.1.4 Плана НИТР Росгидромета, 2020–2024 гг. «Мониторинг состояния и загрязнения природной среды, включая криосферу, в Арктическом бассейне и районах научно-исследовательского стационара «Ледовая база Мыс Баранова», Гидрометеорологической обсерватории Тикси и Российского научного центра на архипелаге Шпицберген».</funding-statement><funding-statement xml:lang="en">This study was made within the framework of Project 5.1.4, «Monitoring of State and Pollution of the Environment, Including the Cryosphere, in the Arctic Basin and in the Area of Scientific Station Ice Base Cape Baranov, Hydrometeorological Observatory of Tiksi and Russian Scientific Centre on Spitsbergen», within the Plan NITR of Roshydromet 2020–2024.</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">Матишов Г.Г., Бердников С.В., Жичкин А.П., Макаревич П.Р., Дженюк С.Л., Кулыгин В.В., Яицкая Н.А., Поважный В.В., Шевердяев И.В., Кумпан С.В., Третьякова И.А., Цыганкова А.Е.
