Abstract
As is well known, the semidiurnal barometric oscillations indicate that the atmosphere has a free oscillation of a period of 12 hours1. On the other hand, G. I. Taylor's evidence2 from the propagation of waves of explosion points to a free period of 10½ hours. Moreover, the diurnal variation of the earth's magnetic field, when interpreted by the dynamo theory, shows3 that at the upper conducting layer the pressure oscillations are nearly 180° out of phase with the observed pressure oscillations at the ground. Also, the required conductivity of the layer is larger than the value that can be inferred from radio soundings.
