ATMOSPHERIC GRAVITY WAVES FROM NUCLEAR EXPLOSIONS

Abstract

Atmospheric gravity waves excited by nuclear explosions were recorded on several occasions in 1967 and 1968 on a large aperture (250x200 km) array of long-period microbarographs (1 to 60 min period pass-band) in the New York- New Jersey area. The spectrum of these wave peaks near a period of 15 min and their average group velocity (about 600 m sec-//1), their dispersion and attenuation conform to theoretical predictions for the surface mode.
