TitleAsymmetry in the Inward-Outward Polarity in the Interplanetary Magnetic Field
AuthorsA.B.Asgarov, V.N. Obridko
AbstractDistribution of the magnetic field of solar wind near the Earth was investigated and compared with one expected from the classical model. It is shown that the presence of two peaks in the distribution of interplanetary magnetic field values, founded by Belov, Obridko and Shelting (2006), is not an artefact of averaging but reflects the real structure of magnetic field inside a sector. Moreover, the magnetic field of the polarity corresponding to the leading sunspot of the Northern Hemisphere is observed more frequently. With solar activity rise the growth of both the module of a magnetic field and the fields of each polarity separately were determined. The distance between peaks increases from 6 nT to 10 nT. In alternate amplification of peaks a quasi-22-year cycle was observed while in the intensity of a field of each polarity there was revealed a 11- year cycle, and in ratio of peaks to frequency of occurrence of zero values – a quasi-2-year (2.6±0.3 year) cycle. Approximately in 25 % of all cases the classical model is violated.
