| Abstract |
Within the framework of the model of a viscoelastic Earth, the tidal deformations caused by its motion by inertia around the center of mass are determined. The obtained expressions for the pole tide differ from the generally accepted model in dissipative terms. These terms are determined by the speed of the pole but not by its position. The analysis of the dynamics of the Earth’s pole motion at the Chandler frequency is carried out taking into account the pole tide. It is shown that the optimal approximation of the pole tide parameters according to the generally accepted model does not lead to the optimal approximation of the parameters of the steady state pole oscillation. |
