Abstract

The dynamic analysis of the Earth pole oscillatory motion is used to study the gravitational-tidal mechanism of formation of the annual component of the process. The results of an analysis of the interaction between the fine resonance structure of the long-period perturbation and the diurnal and semidiurnal tides are used to derive equations for the amplitude and phase of the oscillatory process of six-year pole wobble.
