Variations in Earth Rotation
Author: Dennis D. McCarthy
Publisher: American Geophysical Union
ISBN: 0875904599
Category : Science
Languages : en
Pages : 197
Book Description
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 59. As part of the Nineteenth General Assembly of The International Union of Geodesy and Geophysics Symposium (IUGG) in Vancouver, Canada, Union Symposium U4, "Variations in Earth Rotation" was held August 18-19 1987. The Convenor was Dennis D. McCarthy, U.S. Naval Observatory with P. Paquet, Observatoire Royal de Belgique and M. G. Rochester, St. Johns University serving as co-convernors. In a session on internal structure of the Earth papers dealt with the geophysical effects on Earth rotation parameters. Mantle anelasticity increases the free core nutation (FCN) period by a few days. The period of the FCN and the amplitudes of the main nutation components are sensitive to the ellipticity of the core?]mantle boundary (CMB), and a non-hydrostatic increase of 400m in the flattening of the CMB is a possible explanation of the discrepancies from theory. An alternative suggestion rests on the subseismic description of the nutation spectrum of the stratified liquid core. Evidently new models will have to take into account contributions from the oceans, mantle anelasticity, non-hydrostatic pre-stress, CMB topography and internal core structure.

The Interaction Between Earth's Rotation and Geophysical Processes
Author: Nikolay S. Sidorenkov
Publisher: John Wiley & Sons
ISBN: 3527627731
Category : Science
Languages : en
Pages : 317
Book Description
Filling an important gap in the geophysical literature at specialist level, this monograph is the only up-to-date title to provide a link between the Earth's rotation and its atmo- and hydrosphere, including the ice masses. Starting with the Earth's motions, the text goes on to look at irregularities and the effect of atmospheric processes on the Earth's spin. Tides and seasons occupy the following sections before a discussion of the Earth-ocean-atmosphere system and the mechanical action of the atmosphere on the Earth's rotation. The whole is rounded off by an index of abbreviations and appendices with sections on related physics for better readability, plus a comprehensive bibliography for further reading. A must for geophysicists, oceanographers, glaciologists, climatologists and meteorologists alike.

New Approaches In Geomagnetism And The Earth's Rotation
Author: S Flodmark
Publisher: World Scientific
ISBN: 9814611212
Category : Science
Languages : en
Pages : 298
Book Description
The rotation of the Earth and its relation to geomagnetism are topics that have been under debate for more than a century. In this volume both of these phenomena are discussed in the light of new approaches. Keith Runcorn presents a survey of the papers and concluding remarks. F Richard Stephenson gives a thorough review of the history of the Earth's rotation whilst Stig Flodmark finds an explanation for the Chandler wobbles and the drift of the polar axis. A New Approach to Polar Motion by Losito et al. gives another view of the same theory. The fascinating idea of a single-crystal inner core is discussed by Flodmark and Weber and magnetic rigidity in the Earth is a new concept dealt with by Mörner. The mechanisms behind magnetic reversals, ice ages and earthquakes are other subjects under debate. It is hoped that the present volume will encourage forthcoming debates on these subjects.

Earth Rotation: Solved and Unsolved Problems

Pages : 339
Book Description
The idea for organl.zl.ng an Advanced Research Workshop entirely devoted to the Earth rotation was born in 1983 when Professor Raymond Hide suggested this topic to the special NATO panel of global transport mechanism in the Geosciences. Such a specialized meeting did not take place since the GEOP research conference on the rotation of the Earth and polar motion which was held at the Ohio State University (USA) in 1973. In the last ten years, highly precise measurements of the Earth's rotation parameters and new global geophysical data have become available allowing major advance to be made in the under standing of the various irregularities affecting the Earth's rotation. The aim of the workshop was to bring together scientists who have made important contributions in this field during the last decade both at the observational and geophysical interpretation levels. The confe rence was divided into four main topics. The first session was dedicated to the definition, implementation and maintenance of the terrestrial and celestial reference systems. A few critical points have been identified as requiring further improvements: (i) appro priate selection of terrestrial sites recognized for their long term stability, (ii) determination of the relationship between terrestrial and celestial references systems as well as between the various terrestrial ones, (iii) improvment of the theory of a rotating elastic earth (the recently adopted theory needs already some corrections').

ISBN: 3642755879
Category : Science
Languages : en
Pages : 287
Book Description
Earth's Rotation from Eons to Days reviews long-term changes, methods of measurement, and the major influences on rotation parameters. In order to understand secular changes, the momentary behavior of ocean tides must be analyzed and appropriately modelled.
