Tidal effects in geomagnetic variations

Аннотация

This paper reports the results of processing and analysis of geomagnetic variations, estimates of their spectra, and the first identified waves of lunar–solar tides on the geomagnetic variation envelopes in the circadian range and in the periods of 13.66 and 27.55 days. The specific features of the geomagnetic variation spectrum open up new possibilities for evaluation of the viscosity of the Earth’s outer core, description of the geomagnetic dynamo, development of new models of movement of the Earth’s inner core and the current system dynamics in the outer (liquid) core, and establishment of the general regularities controlling the energy exchange conditions in the geosphere.
