Abstract : As is known, westerly electric current loops occur in winter in the polar cap region. Changes in the magnetic field in the region are indicative of the phenomenon. It appeared that currents in a circle 80 degrees wide were running as a rule from the 22 hour meridian to the 10 hour meridian. However, this main direction can change with time. It can be assumed that the indicated temporary changes can be utilized as an important property of interaction between the earth's magnetic field and corpuscular radiation of the sun. As a result, they constituted an independent object of investigation. The data of Arctic and Antarctic stations lying above lat. 75 degrees and collected during 1957-1964 show cyclic and seasonal changes in the direction of currents, as well as the relation between the direction of SD currents, the velocity of solar wind and intensity of neutron components of cosmic rays. The close statistical link that was established during the study suggests that the observed phenomena have common causes. (Author)
