Simplified normal mode treatment of long-period acoustic-gravity waves in the atmosphere
ResearchPublished 1965
A discussion of the effects of geometric dispersion due to stratification of the atmosphere on low-frequency mechanical waves generated by nuclear explosions. It is found that the pressure signal can be divided naturally into an early-arriving acoustic-gravity portion and a later acoustic portion, both portions being inversely proportional to the range (geometric spreading included). Most of the signal is composed of many propagating modes which, at a given range and time, will each demonstrate a characteristic frequency. A simplified treatment for the high-frequency portion is appropriate.
