This book was released on 1972 with total page 523 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the Symposium was to convene Specialists in Physics of the atmosphere engaged in the study of energy transfers in the form of waves in a neutral medium and Specialists in Electromagnetic Wave Propagation concerned with the corresponding modifications of the electric characteristics of the medium and their effects on Electromagnetic Waves. The program has been divided in five sessions: Acoustic gravity waves in the neutral terrestrial atmosphere; Coupling between the ionized atmosphere and the neutral atmosphere disturbed by acoustic gravity waves; Radio electric studies on acoustic gravity waves in the neutral and ionized atmosphere; Influence of acoustic gravity waves on the propagation of electromagnetic waves; Summaries recommendations and future investigations.

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).

Available in PDF, EPUB and Kindle. Book excerpt: In this report we review the theory of acoustic-gravity waves, the interaction of such waves with the ionosphere, the experimental support for the existence of such waves in the upper atmosphere, and the role played by acoustic-gravity waves in thermospheric dynamics. After a thorough discussion on the properties of acoustic-gravity waves in an ideal isothermal atmosphere, the effects produced by horizontal winds, sharp boundary discontinuities, and dissipative processes are discussed. These discussions are followed by reviewing propagation effects in a realistic atmosphere for both free waves and guided waves. The propagation of these acoustic-gravity waves in the upper atmosphere may induce changes in the ionosphere sometimes known as traveling disturbances. The existing experimental data on traveling disturbances are then reviewed and found consistent, in most cases, with the acoustic-gravity wave interpretation.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The generation of acoustic and internal gravity waves in the earth's atmosphere by nuclear detonations is considered. Attention is given to a general statement of the problem and to the assessment of the importance of various generation mechanisms in the flows produced by nuclear explosions. From the significant source mechanisms, the corresponding wave emissions are estimated with reference to nuclear detonation outputs. (Author).
