Microbarograph Record of Waves from the Chinese Thermonuclear Explosion on June 17, 1967

Abstract

AN unusual train of waves, characteristic of a distant and violent disturbance of the atmosphere, began to be received on a microbarograph¹ in Aberdeen at about 0545 h G.M.T. on June 17, 1967. The unusual train, which lasted about an hour, was superimposed on a much longer and more usual series of waves of period about 12 min and amplitude 250 microbars; such waves, which are of natural origin, are characteristically received during meteorological inversions.
