In the Earth-Moon system, oscillations of close frequencies can be transformed as a result of the degree of coupling. The observed extended period of the Chandler oscillations can be explained by coupling of the oscillations. The problem of amplitude and period variations of the main oscillations of the Earth poles is treated on the basis of parametric excitement. For the first instability region an equation is obtained to determine the amplitudes of possible steady-state solutions. The variation limits of Chandler period oscillations and the relation between amplitudes of a possible steady-state solution for two periodic polar motion components are computed. The possible influence of energy exchange in coupled Earth-Moon oscillations on excitement and self-excitement in geophysical processes is discussed. As an illustration the interaction between the Earth's angular velocity variations and variations in the Siberian anticyclone parameters are considered.
