Description
Summary:In this paper the data of geomagnetic pulsations at Zhongshan Station from February 3 to November 30 in 1996 are analyzed in order to study polarization characteristics of Zhongshan Station Pc3 pulsation. For the cusp Pc3 pulsation, the right-handed polarization is always dominant. But their orientation of major axes of polarizations changes with season, NW-SE is dominant in summer and NE-SW in winter. For the nightside Pc3 pulsation, the right-handed with NE-SW is always dominant before midnight. But the left-handed with the mixing orientation of major axes is dominant in summer and the NE-SW with the mixing polarization sense is dominant in winter after midnight. It means that the two types of Zhongshan Station Pc3 pulsations have different sources.
