Geometrical Acoustics Techniques in Far Field Infrasonic Waveform Syntheses.

Abstract : The present report is concerned with the development of a computational model for the prediction of long range infrasound propagation in the atmosphere. The computational model discussed here is one which is partly based on ray acoustic concepts; it should be applicable to wave periods less than three minutes and is intended to complement the guided mode model of acoustic gravity wave propagation which has been extensively discussed in previous reports and papers.
