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.

考虑到月球扰动的地球极运动的短期预测

摘要-

在数值分析的基础上，研究了地球极的扰动。显示了振荡过程的各种模式的存在，这些模式会影响预测其位置的准确性。发现扰动会导致地球极的平均速度发生变化，并导致其振荡模式发生变化。提出了一种构造低参数双频模型的修改方法，该方法可以提高短时间间隔内预测地球极运动的准确性。
