- Abstract
Anumerical-analytical model for oscillatory motions of the Earth's pole that can provide qualitative explanations for irregular oscillatory phenomena and improvements in the accuracy of forecasting the polar trajectories in periods of significant anomalies is proposed. The model represents a natural refinement of the main model for the polar oscillations (the Chandler and annual components) developed earlier using celestial mechanics methods and observations of the Earth's gravitational field. The results of numerical simulations of the polar oscillations are compared with measurements carried out by the International Earth Rotation Service.
