Summary: | The temperature and radiation regimes of the Elbrus mountain area were reconstructed for summer seasons of 1948–2013 using observational data obtained by expeditions of the Institute of Geography of the Russian Academy of Sciences and the Faculty of Geography of the Lomonosov Moscow State University together with NCEP/NCAR reanalysis. This made possible to analyze in details the meteorological conditions and to calculate statistical characteristics of both the air temperature and the radiation components. The reanalysis data were compared with the observational ones for the purpose to estimate an applicability of the reanalysis techniques for reconstruction of the Elbrus temperature regime. Using the above data the temperature trends were analyzed for the last 65 years, and the hypothesis on possible physical mechanisms of intensive glacier melting of the Central Caucasus in the XXI century had been formulated. На основе материалов наблюдений, полученных в экспедициях Института географии РАН и географического факультета МГУ имени М.В. Ломоносова, в сочетании с данными реанализа NCEP/NCAR проведена реконструкция температурного и радиационного режима Эльбруса в летний сезон за период 1948–2013 гг. Проанализированы данные метеорологических измерений, оценены основные статистические характеристики рядов температуры и компонентов радиационного баланса. Выполнено сравнение данных реанализа с натурными исследованиями, сделаны предположения о применимости реанализа для реконструкции термического режима горы Эльбрус. На основе восстановленных данных анализируются тренды температуры за последние 65 лет, формулируется гипотеза о возможных физических механизмах интенсивного таяния ледников Центрального Кавказа в XXI в. |
