Abstract : The theory of the propagation of long-period infrasonic waves from nuclear explosions in the atmosphere is reviewed and the extensions of the theory developed under Contract AF19(628)-3891 are described. A simple demonstration of the theoretical basis of amplitude-yield proportionality is given and work on the extension of the normal mode method to include non-stratified windy atmospheres is described. The formulation for incorporating wind effects into theoretical models is reviewed. A justification of the multilayer method is given and numerical results based on this approximation are summarized. The report includes a listing of all reports, journal articles, and symposia papers written under the contract and includes an extensive bibliography on atmospheric waves and nuclear explosions. Recommendations for future research are given. (Author)
