On the Disturbances of the Earth's Electromagnetjc Field

[摘要] Theory of electrodynamics gives us the orthogonal relations between E and H which enable us to c_??_lculate electric and magnetic components of variable field. Employing these values the present author studied the nature of disturbances.It was shown from the treatment of Poynting vector that the origin of the flow of energy is in the upper layer of the polar region, and its intensity is about 1.5 × 10-3 ergs/cm2secComparisons of the theoretical results with observations have also led to the determinations of the specific resistance of the order of 2 × 105 ohms cm.
