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 کاملUnusual cerebellar ataxia: "worm wobble" revisited.
We present an unusual case of cerebellar ataxia in a 2 year old girl several days after treatment with piperazine citrate for suspected worm infestation. This is the first reported case of delayed onset neurotoxicity following the therapeutic administration of piperazine in a previously well child.
متن کاملAtmospheric Excitation of the Earth ' s Annual Wobble ' 1980 - 1988
Global meteorological analyses from the European Centre for Medium Range Weather Forecasts are employed to compute the atmospheric excitation ß of the polar motion for the 9-year period of 1980-1988. Both the matter component V(matter) and the motion component V(motion) are computed, the former with and without the oceanic inverted barometer (lB) effect. It is found that V(motion) contributes s...

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 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...
