Представлены результаты изотопных исследований нескольких ледяных кернов, полученных на Западном плато Эльбруса (Кавказ). В изотопном составе кернов прослеживается чёткий сезонный сигнал. Рассчитаны среднегодовые и среднесезонные значения изотопного состава и скорости снегонакопления за 89 лет (с 1924 по 2012 г.). Эти значения сопоставлены с данными метеонаблюдений в регионе и с характеристиками циркуляции атмосферы. Показано, что в тёплый период года изотопный состав зависит от температуры воздуха в регионе, а в холодный-от особенностей циркуляции атмосферы. The results of the isotopic investigations of several ice cores obtained at the Western Plateau of Mt. Elbrus (the Caucasus) are presented. There is a distinct seasonal cycle in the isotopic composition record in these cores. Mean annual and seasonal values of the isotopic composition and accumulation rate were reconstructed for 89 years (1924-2012). These values were compared with the available regional meteorological data and the atmospheric circulation characteristics. It was shown that in the summer season the isotopic composition reflects the local temperature while in winter it depends on the atmospheric circulation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
