description |
Contemporary thinning of the marine-based areas of ice sheets is believed to be the consequence of the grounding line retreat caused mainly by ocean gradual warming beneath the ice shelves. In order to estimate potential contribution of ice sheets into the future sea-level rise grounding line migration must be accurately described in the mathematical models. We incorporated an algorithm based on application of the boundary condition on the mass flux across the grounding line into a two-dimensional ice flow model. In the numerical experiments, externally forced ice sheet returns to its initial equilibrium state after termination of the external forcing (either accumulation rate or sea-level change anomalies). In future, the model will be modified to incorporate buttressing effect. Объём ледниковых щитов, основание которых лежит ниже уровня моря, сокращается главным образом в результате смещения линии налегания в глубь континентальной области предположительно в результате потепления окружающих его вод океана. Для оценки потенциального вклада ледниковых щитов в будущее увеличение уровня моря в математических моделях необходимо как можно точнее описывать процесс миграции линии налегания. В статье рассматривается алгоритм миграции, в основе которого лежит задание граничного условия потока массы на линии налегания. В численных экспериментах ледниковый щит, будучи выведенным из равновесия внешним воздействием, возвращается к своему первоначальному состоянию при прекращении действия внешней силы. После соответствующей доработки алгоритм можно применять в комплексных моделях ледниковых щитов. |
