A numerical analytical refined model of a short term forecast of the Earth’s pole motion is proposed. The model allows to increase the accuracy of predicting the coordinates of the pole with observed irregular effects in its motion. A numerical simulation of the oscillatory motion of the Earth’s pole is carried out in comparison with the data of observations and measurements of the International Earth Rotation Service, and the accuracy characteristics of the model are investigated.

非平稳扰动引起的地极运动

提出了对地球极运动的短期预报的数值分析精化模型。该模型允许在观察到极点运动不规则影响的情况下提高预测极点坐标的准确性。与国际地球自转处的观测和测量数据相比较,对地球极的振荡运动进行了数值模拟,并研究了模型的准确性。
