Гренландский ледниковый щит на пике потепления предыдущего межледниковья
https://doi.org/10.15356/2076-6734-2014-2-91-101
Аннотация
Последние исследования показали, что уровень Мирового океана в предыдущее межледниковье мог превышать современный на 6–9 м. Однако до настоящего времени вопрос об источниках этого повышения дискуссионен. Исследования вклада Гренландского ледникового щита в повышение уровня Мирового океана, основанные на использовании методов математического моделирования, дают значения от 60 см до 6 м. Подобный разброс объясняется чувствительностью любой модели Гренландского ледникового щита как к климатическим условиям, так и к особенностям описания летнего таяния в пограничной области. Климатические условия предыдущего межледниковья в Гренландии изучены недостаточно, особенно мало информации о региональном распределении температуры воздуха и количества осадков. Летнее таяние представляет собой сложный нелинейный процесс с рядом положительных обратных связей, для описания которого применяют различные параметризационные схемы. В настоящей работе вместо исследования климатических условий в течение предыдущего межледниковья генерируется ансамбль различных «климатов» и изучается множество модельных конфигураций Гренландского ледникового щита. Использование информации, полученной по пяти гренландским ледяным кернам, позволяет значительно ограничить число возможных межледниковых конфигураций. Объективные критерии показывают, что максимальный вклад Гренландского ледникового щита в повышение уровня моря составляет 1,8–2,2 м.
