- Abstract
A numerical–analytical approach is used to investigate irregular effects in oscillations of the Earth's pole related to variations in the Chandler and annual components. An approach to studying oscillations in the motion of the Earth's pole based on a joint analysis of the Chandler and annual components of this motion is proposed. A transformation to a new coordinate system in which the motion of the pole is synchronous with the precession of the lunar orbit can be found in this approach. Estimates of the precision of predictions of the coordinates of the Earth's pole taking into account additional terms due to lunar perturbations are presented.
