On Some Similarties between the Variation of the Terrestrial Magnetism and the Atmospheric Eiectricity

Abstract

The Present author investigated the variations of the terrestrial magnestism, the atmospheric electricity and the earth-current using the data obtained at the Kakioka and the Toyohara Magnetic observatory.
The diurnal variation of the atmospheric potential gradient indicates the existence of the longitudial current flow in the lower strata of the aimosphere, and the variations in the in this currcntsystem may cause the induction current in the earth's crust. The existence of this induction effect was verifed with magnetic records.
From the short period variation, we can also deduce some similarities between the variation of the terrestrial magnetism and the earth-currert.The bay-disturbance in the terrestrial magnetic field with sufficient results.
