An Empirical Study of Infrasonic Propagation

摘要: Observations of atmospheric nuclear tests carried out at the Nevada Test Site from 1951 to 1958 provided data for an empirical investigation how infrasonic signals are propagated distances about 250 km. Those observations and analysis documented in this report involved signal amplitudes average velocities included three classes signals: stratospheric, thermospheric, tropospheric/surface. The authors' showed that stratospheric winds have a dominant effect upon amplitudes. outlines method normalizing effects upper presents equations predicting or amplitude velocity types signals.
