Abstract:

A discussion is given of theoretical studies on infrasound propagation through the atmosphere which were carried out under the contract. Topics discussed include 1 the modification and adaptation of a computer program for the prediction of pressure signatures at large distances from nuclear explosions to include leaking guided modes, 2 the nature of guided infrasonic modes at higher infrasonic frequencies and the methods of extending waveform synthesis procedures to include higher frequencies, and 3 the propagation of infrasonic pressure pulses past the antipodes over halfway around the globe. Summaries are included of all papers, theses, and reports written under the contract and conclusions and recommendations for future studies are given.
