VARIATION OF THE MASS OF THE ICE SHEET OF ANTARCTICA AND INSTABILITY OF THE EARTH'S ROTATION

摘要

A theoretical series of the Antarctic ice mass variation from 1891 to 2000 is calculated using astronomical data on the movement of the North Pole and variation in the velocity of the Earth's daily rotation. The series is compared with the data of V. N. Petrov on the annual layers of snow accumulation in Antarctica and precipitation series at Antarctic stations. It is shown that the theoretical series agrees well with results of actual snow measurements. It is concluded that the theoretical series can be used to test the results of empirical studies of the temporal variability of the ice sheet of Antarctica and of atmospheric precipitation in Antarctica.
