Is the Chandler Period Stable?

Estimation of the pole tide gravimetric factor at the chandler period through wavelet filtering

S U M M A R Y Wavelet analysis for filtering is used to improve estimation of gravity variations induced by Chandler wobble. This method eliminate noise in superconducting gravimeter (SG) records with bandpass filters derived from Daubechies wavelet. The SG records at four European stations (Brussels, Membach, Strasbourg and Vienna) are analysed in this study. First, the earth tidal constituent...

Autobiography of David Chandler.

I was born the younger of my parents’ two children, on October 15, 1944, at Brooklyn Jewish Hospital, in New York. Except for two years when I was five and six years old, I spent my formative years in Great Neck, a north shore Long Island suburb of New York City, where I benefited from material comforts, excellent schools, and abundant opportunities for cultural and recreational activities. My ...

The excitation of the Chandler wobble

The Chandler wobble is an excited resonance of the Earth's rotation having a period of about 14 months. Although it has been under investigation for more than a century, its excitation mechanism has remained elusive. Here, the angular momentum of the atmosphere computed from the products of a numerical weather prediction analysis system and the angular momentum of the oceans computed from a glo...

New Stable Period Gait in Compass Model

This paper presents a new steady periodic gait in the compass model. It is proved that the model has period-four gait and the new gait lead to chaos through perioddoubling bifurcation. This paper confirms the existence of the new gait and its bifurcation through the calculation by computer.
