ASYMMETRY OF DST VARIATIONS OF GEOMAGNETIC STORMS WITH RESPECT TO THE GEOMAGNETIC EQUATOR
Abstract
The seasonal variations in the Dst part of magnetic storms are determined for three pairs of stations, each pair consisting o two stations at nearly equal geomagnetic latitudes in the northern and southern hemispheres. The results show that in solstitial seasons the Dst field is not symmetrical with respect to the geomagnetic equator. The asymmetry is small in low latitudes and increases toward the auroral zones. Dm has a similar asymmetry with respect to the equator. These characteristics of Dst and Dm are interpreted as due to the asymmetry of auroral electrojets with respect to the geomagnetic equator in solstitial seasons. (Author)
