This book was released on 1965 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this research was to obtain a panoramic view of acoustic-gravity-wave motions throughout the atmosphere. A one-dimensional array of particles and springs, conceived by Newton to study sound waves in the atmosphere, was extended to two dimensions by means of 1500 particles interconnected by springs. Variations of density and pressure with altitude are represented by variations in mass and spring constants. This new model has provided means by which acoustic-gravity-wave motions in the atmosphere are solved on a high-speed digital computer, and a new animated-computer-output technique is used. A motion picture--automatically plotted by the computer, a frame at a time--provides greater detail and perspective of mechanical wave motions in the atmosphere than has ever been obtainable before. Ground-level and 100-km-high explosions were investigated with this computer model, and the resulting transient motions of the atmosphere were displayed by means of a motion picture produced by digital techniques. Computed ground-level barograms resulting from a ground-level explosion compare well with experimental barograms recorded during ground-level nuclear explosions. (Author).

Book Synopsis Infrasound Monitoring for Atmospheric Studies by : Alexis Le Pichon
Download or read book Infrasound Monitoring for Atmospheric Studies written by Alexis Le Pichon and published by Springer Science & Business Media. This book was released on 2010-01-19 with total page 735 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of infrasound to monitor the atmosphere has, like infrasound itself, gone largely unheard of through the years. But it has many applications, and it is about time that a book is being devoted to this fascinating subject. Our own involvement with infrasound occurred as graduate students of Prof. William Donn, who had established an infrasound array at the Lamont-Doherty Geological Observatory (now the Lamont-Doherty Earth Observatory) of Columbia University. It was a natural outgrowth of another major activity at Lamont, using seismic waves to explore the Earth’s interior. Both the atmosphere and the solid Earth feature velocity (seismic or acoustic) gradients in the vertical which act to refract the respective waves. The refraction in turn allows one to calculate the respective background structure in these mediums, indirectly exploring locations that are hard to observe otherwise. Monitoring these signals also allows one to discover various phenomena, both natural and man-made (some of which have military applications).

Book Synopsis Supplemental Atmospheres by : A. Court
Download or read book Supplemental Atmospheres written by A. Court and published by . This book was released on 1962 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atmospheres typical of the tropics (15 degrees N), sub-tropics (30 degrees N), and mid-latitudes (45 degrees N) were prepared as members of a family of atmospheres supplemental to the 1962 US Standard Atmosphere; they provide information on latitudinal and seasonal changes in atmospheric structure up to 90 km. Temperature gradients for various segments are linear with geopotential height. Humidity is incorporated into the lowermost 10 km of each atmosphere. Figures and tables depict temperature, relative humidity, pressure, and density, The atmospheres are mutually consistent; zonal wind profiles computed from the geostrophic wind equation at selected pressure heights compare favorably with existing rawinsonde and Meteorological Rocket Network wind observations.

Book Synopsis Internal Gravity Waves by : Bruce R. Sutherland
Download or read book Internal Gravity Waves written by Bruce R. Sutherland and published by Cambridge University Press. This book was released on 2010-09-02 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of internal gravity waves provides many challenges: they move along interfaces as well as in fully three-dimensional space, at relatively fast temporal and small spatial scales, making them difficult to observe and resolve in weather and climate models. Solving the equations describing their evolution poses various mathematical challenges associated with singular boundary value problems and large amplitude dynamics. This book provides the first comprehensive treatment of the theory for small and large amplitude internal gravity waves. Over 120 schematics, numerical simulations and laboratory images illustrate the theory and mathematical techniques, and 130 exercises enable the reader to apply their understanding of the theory. This is an invaluable single resource for academic researchers and graduate students studying the motion of waves within the atmosphere and ocean, and also mathematicians, physicists and engineers interested in the properties of propagating, growing and breaking waves.

Book Synopsis The Effect of Ambient Vibrational Nonequilibrium on the Propagation of Acoustic-gravity Waves by : Jayaraman Srinivasan
Download or read book The Effect of Ambient Vibrational Nonequilibrium on the Propagation of Acoustic-gravity Waves written by Jayaraman Srinivasan and published by . This book was released on 1974 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is a theoretical study of the effect of ambient vibrational nonequilibrium(vibrational or radiative) on the propagation of acoustic and gravity waves in a gas. In the propagation of such waves, nonequilibrium phenomena can manifest themselves in two distinct ways. This follows from the fact that nonequilibrium can exist in either(or both) the ambient and perturbed states of the gas. It is well known that perturbation nonequilibrium always contribute to damping of the waves. The lesser known effects of ambient nonequilibrium are examined here from the point of view of macroscopic gas dynamics. The physical insight obtained in a one-dimensional analysis is applied to the study of the probable effect of vibrational nonequilibrium(ambient and perturbation) on the propagation of acoustic-gravity waves in Earth's upper atmosphere.

Book Synopsis Theoretical Global Seismology by : F. A. Dahlen
Download or read book Theoretical Global Seismology written by F. A. Dahlen and published by Princeton University Press. This book was released on 2020-08-04 with total page 1040 pages. Available in PDF, EPUB and Kindle. Book excerpt: After every major earthquake, the Earth rings like a bell for several days. These free oscillations of the Earth and the related propagating body and surface waves are routinely detected at broad-band seismographic stations around the world. In this book, F. A. Dahlen and Jeroen Tromp present an advanced theoretical treatment of global seismology, describing the normal-mode, body-wave, and surface-wave methods employed in the determination of the Earth's three-dimensional internal structure and the source mechanisms of earthquakes. The authors provide a survey of both the history of global seismological research and the major theoretical and observational advances made in the past decade. The book is divided into three parts. In the first, "Foundations," Dahlen and Tromp give an extensive introduction to continuum mechanics and discuss the representation of seismic sources and the free oscillations of a completely general Earth model. The resulting theory should provide the basis for future scientific discussions of the elastic-gravitational deformation of the Earth. The second part, "The Spherical Earth," is devoted to the free oscillations of a spherically symmetric Earth. In the third part, "The Aspherical Earth," the authors discuss methods of dealing with the Earth's three-dimensional heterogeneity. The book is concerned primarily with the forward problem of global seismology--detailing how synthetic seismograms and spectra may be calculated and interpreted. As a long-needed unification of theories in global seismology, the book will be important to graduate students and to professional seismologists, geodynamicists, and geomagnetists, as well as to astronomers who study the free oscillations of the Sun and other stars.
