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...
متن کامل2 6 A ug 2 00 9 Chandler wobble : two more large phase jumps revealed
Investigations of the anomalies in the Earth rotation, in particular, the polar motion components, play an important role in our understanding of the processes that drive changes in the Earth’s surface, interior, atmosphere, and ocean. This paper is primarily aimed at investigation of the Chandler wobble (CW) at the whole available 163-year interval to search for the major CW amplitude and phas...

Viscosity of the D00 layer of the Earth’s mantle, the lowermost layer in the Earth’s mantle, controls a number of geodynamic processes, but a robust estimate of its viscosity has been hamp...
متن کاملAutobiography 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 ...
متن کاملAutoregressive Harmonic Analysis of the Earths Polar Motion Using Homogeneous International Latitude Service Data
The homogeneous et of 80-year-long (1900-1979) International Latitude Service (ILS) polar motion data is analyzed using the autoregressive method (Chao and Gilbert, 1980), which resolves and produces estimates for the complex frequency (or frequency and Q) and complex amplitude (or amplitude and phase) of each harmonic component in the data. Principal conclusions of this analysis are that (1) t...
