Prediction of the Chandler wobble
2014Chandler wobble amplitude have been decreasing in 2010s as in 1930s. We try to predict its future behaviour through prediction of its complex envelope. The excitation of the Chandler wobble(ChW) reconstructed by Panteleevs filter was also analized.

The source of the variable Chandler wobble
2010n the absence of forcing, the Chandler wobble (CW) would have a period of 430.3 days, and would lose most of its energy after a few decades because of dissipation in the mantle and in the oceans. Observation of the Earths polar motion, however, reveals a prograde oscillation of which pseudo period can be as far as 20 days from the above value (Vondrak ...

Phase and amplitude variation of Chandler wobble
2011Normally, the wobble of the earth has been dealt with in a manner that assumes that the two main periodic components have constant phase and amplitude. An initial assumption of this thesis is that both these parameters can vary with time. A technique of predictive filtering is used to determine the Chandler component of the wobble from basic latitude ...
