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 ...

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.

Seismic Excitation of the Chandler Wobble
1970Results from the elasticity theory of dislocations as well as observational evidence are presented in support of the hypothesis of seismic excitation of the Chandler wobble. There appears to be a high degree of correlation between changes in the pole path and earthquakes with M > 7.5 in the 11 year period from 1957.0 to 1968.0.

Responses of the ocean to the Chandler wobble
Marine Geodesy, 1983Abstract This paper presents a feasible status report on the responses of the ocean to the Chandler wobble through analyses of sea‐level and sea‐surface temperature variations. The analysis of sea level employs a method to determine the simplest impulse response system of ocean to the Chandler wobble by a least‐squares fitting after operation of an ...

On the Chandler wobble. I. Theory
Chinese Astronomy and Astrophysics, 1981Abstract This paper introduces the idea that there exists a nutation separation layer in the superficial zone of the Earth, thereby sets up a new model of nutation. The equations of motion are derived and solved. It is proved that the separation layer is “soft”, and is probably located at a depth of 300 km from the surface.
