Book Synopsis The Rotation of the Earth by : Walter H. Munk
Download or read book The Rotation of the Earth written by Walter H. Munk and published by Cambridge University Press. This book was released on 2009-03-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives an account of certain observed irregularities on the rotation of the Earth, both in its rate of rotation (giving a variable length of day) and in the position of its axis. These irregularities are caused by events on and within the Earth and provide a means of studying a number of geophysical problems. Seasonal shifts in air masses and variable winds are causes of short-period fluctuations in the rotation. Climatic changes and their attendant sea levels are in part responsible for long-term fluctuations. Modern observations of the Moon and descriptions of ancient elipses both establish a secular increase in the length of day. The interpretation involves atmospheric, oceanic and bodily tides. The book provides a unified treatment of the rotation of the Earth, making this method of studying geophysical phenomena more readily accessible to geophysicists and others.

Book Synopsis Time and the Earth’s Rotation by : D.D. McCarthy
Download or read book Time and the Earth’s Rotation written by D.D. McCarthy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: IAU Symposium No. 82, "Time and the Earth's Rotation", met to discuss modern research in the field of the rotation of the Earth with particu lar emphasis on the role of new observational techniques in this work. The use of these techniques has prompted a new look at the definitions of the traditional reference systems and the concepts of the rotation of the Earth around its center of mass. Specific topics discussed were time, polar motion, reference systems, conventional radio interferometry, very'long baseline interferometry (VLBI), Doppler satellite methods, satellite laser ranging, lunar laser ranging, and geophysical research concerning the Earth's rotation. Improvement in the accuracy of the observations is a key to possible solutions of the many unsolved problems remaining in this field. It appears that such improvement, using both classical and new techniques, is forthcoming in the near future. This will surely contribute to a better understanding of some of the long-standing questions concerning the rotation of the Earth around its center of mass and lead to an improved knowledge of the rotating, deformable Earth. This volume contains the papers presented at IAU Symposium No. 82 as well as the discussions provoked by these papers. It is hoped that it captures the principal points of the meeting and that it will contribute not only to a better understanding of existing problems, but also to future research in time and the Earth's rotation.

Book Synopsis Earth Rotation: Solved and Unsolved Problems by : Anny Cazenave
Download or read book Earth Rotation: Solved and Unsolved Problems written by Anny Cazenave and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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').
Book Synopsis Variations in Earth Rotation by : Dennis D. McCarthy
Download or read book Variations in Earth Rotation written by Dennis D. McCarthy and published by American Geophysical Union. This book was released on 1990 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Tidal Friction and the Earth’s Rotation II by : P. Brosche
Download or read book Tidal Friction and the Earth’s Rotation II written by P. Brosche and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 458 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the four years which elapsed between our first workshop on .Tidal Friction and the Earth's Rotation and the second, the proceedings of which are presented here, many of the disciplines involved made ad vances which we felt should be exchanged. We were encouraged by the good reception our first report met with. Of course, more insight often means more problems. Therefore, this volume contains new results and revisions of matters which previously appeared settled. We are certainly far from "final answers". For this reason, differing opinions on some issues are to be found in this book. Moreover, we have refrained from making mathematical symbols uniform to avoid the risk of errors and non-compatibility with the earlier work of an author. The two workshops have stimulated collaboration between participants working in various fields. The final versions of the contributions have already profited from these discussions. We are convinced that they will also influence further investigations. This advancement of our past and future aims is based on the very existence of the Centre for Interdisciplinary Studies and on the support we have received from its leading members. The authors have agreed to dedicate this book to Dr. H. Gerstenkorn, who died in 1981. He contributed fundamental ideas to the scientific fields treated in the meeting. P.

Book Synopsis Tidal Friction and the Earth’s Rotation by : Peter Brosche
Download or read book Tidal Friction and the Earth’s Rotation written by Peter Brosche and published by Springer. This book was released on 2013-12-01 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: P. Brosche The development of the ideas and observational techniques related to the subject of our meeting "Tidal friction and the Earth's rotation", Bielefeld, September 1977 is one of the most fascinating books - not merely chapters! - of the modern history of science. Its genealogical tree is as intricate as that of mankind itself: There are dead ends and superfluous re-discoveries. Due to these circumstances and to the pure extent of the topic, it is impossible to give more than a few highlights here. The first relevant observational fact was discovered by the famous English astronomer E. Halley in 1695 (Berry, 1961). He simply could not arrive at an agreement between ancient and recent eclipses using a constant mean angular motion of the Moon. Instead, he had to introƯ duce an empirical acceleration term in the mean motion. Known as the "secular acceleration", it has ever since been a most challenging subƯ ject of celestial mechanics and a main branch of the genealogical tree already mentioned. In 1754, completely independently and almost certainly in ignorance of those specialists' activities, the German philosopher Kant established the idea of tidal friction as a decelerating mechanism for the rotation of the Earth (Felber, 1974). Although he made some errors in his rough computations, the majority of the constitutive elements of his concept have survived to the present day (Brosche, 1977).
Book Synopsis New Approaches In Geomagnetism And The Earth's Rotation by : S Flodmark
Download or read book New Approaches In Geomagnetism And The Earth's Rotation written by S Flodmark and published by World Scientific. This book was released on 1991-01-30 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Historical Eclipses and Earth's Rotation by : F. Richard Stephenson
Download or read book Historical Eclipses and Earth's Rotation written by F. Richard Stephenson and published by Cambridge University Press. This book was released on 2008-03-24 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of many years of research, this book discusses ancient and medieval eclipse observations and their importance in studying Earth's past rotation. This is the first major book on this subject in twenty years. The author has specialized for many years in the interpretation of early astronomical records and their application to problems in modern astronomy. The book contains an in-depth discussion of numerous eclipse records from Babylon, China, Europe and the Arab lands. The author provides translations of almost every record studied. He shows that although tides play a dominant long-term role in producing variations in Earth's rate of rotation--causing a gradual increase in the length of the day--there are significant and variable nontidal changes in opposition to the main trend. This book is intended for geophysicists, astronomers (especially those with an interest in history), historians and orientalists.
