| Abstract |
On the basis of a numerical-analytical approach, the disturbed motion of the Earth's pole is investigated. The existence of various modes of the oscillatory process is shown that affect the accuracy of predicting its position. Perturbations are found that lead to a change in the average speed of the Earth's pole and to a change in its oscillatory mode. A method is proposed for constructing a modification of a low-parameter two-frequency model, which makes it possible to improve the accuracy of forecasting the movement of the Earth's pole for short time intervals. |
