Asymmetry in Seasonal Variation of Geomagnetic Activity
journal contribution
posted on 2023-06-07, 20:44 authored by E O Falayi, Natalia BeloffNatalia BeloffSeasonal variations in geomagnetic activities were studied for the period of 1990-2007 using Dst and AE indices. Over 150 events characterised by increase in geomagnetic activity of varying strength (from -90 up to -1800nT) were statistically analysed. Although Russell- McPherron effect plays a major role in the equinoctial asymmetry of the geomagnetic activity, others may also take place. During this study we found a statistically significant October-November peak in geomagnetic activity for Northern Hemisphere, which is sufficiently larger than March-April peak. Several hypotheses for the cause of such effect are discussed.
