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 کاملA variable height "wobble board".
The "wobble board" has been used for many years for the re-education of the musculature of the ankle and foot after injury. Varying heights of board have been used depending on the range of movement required at various stages of recovery but I have not seen, nor have some experienced colleagues seen, one where the height is adjustable. Such a device is here illustrated. It consists of a circula...
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 ...
