On modulations of the Chandler wobble excitation

Journal of Geodynamics, 2012
Abstract We derive the Chandler wobble excitation from the polar motion (PM) observations by using the Panteleev corrective filtering. The latter method is based on inversion of the Euler–Liouville equation, with additional filtering in the Chandler frequency band.

Chandler wobble and geomagnetic jerks

Physics of the Earth and Planetary Interiors, 2001
Abstract Some features of the polar motion may be due to core–mantle coupling, but no convincing quantitative mechanism has yet been proposed. Considering phase jumps in the Chandler wobble and noticing their correlation with geomagnetic jerks [J. Geophys. Res.

Diminished Chandler Wobble After 2015: Link to Mass Anomalies in 2011

Geophysical Research Letters
Abstract Observed polar motion after 2015 is dominated by the annual wobble, due to unprecedented amplitude reduction of the Chandler Wobble component. This change is likely due to suppression of the 433‐day‐period free wobble by geophysical excitation sources.

On the Chandler wobble of Mars

Planetary and Space Science, 1996
Abstract The possibility of determination of the aggregative state and the radius of the Martian core by Chandler wobble data is discussed. The polar motion under consideration is excited by the Martian atmosphere and convective flow in the liquid core.

Theoretical Model for the Chandler Wobble

Nature, 1967
EULER is generally credited with having been the first to show that an axially symmetric rigid body, with a fractional difference between the equatorial and polar moments of inertia equal to that of the Earth, could undergo a free nutation with a period of about 300 days.

The excitation of the Chandler wobble

Surveys in Geophysics, 1988
The cause- or causes-of the excitation of the Chandler wobble is one of the most intriguing problems in geophysics. As a result of one of the most valuable examples of an international programme, the positions of the pole have been determined since the late 19th century with remarkable accuracy.
