Study of Acoustic-Gravity Wave Generation by Nuclear Detonations

Abstract

Conclusions based on previous work done on the contract and published in detail elsewhere are first reviewed. The earlier work treated the generation and propagation of both long period (3-10 minutes) and short period (1-60 seconds) acoustic signals from nuclear detonations. Also included in the review are conclusions reached concerning Rayleigh wave generation by atmospheric explosions. Recent work, reported for the first time, is then described. This consists of: (a) An analysis of the relationship of different kinds of disturbance seen in the ionosphere to the hydrodynamic motions accompanying a low altitude nuclear explosion. Both the detonation blast wave and the buoyant rising fireball are considered as sources of ionospheric disturbance. (b) A laboratory investigation of the internal gravity waves generated by buoyant rise in a density stratified medium.
