Description
Summary:In this paper Pi2 pulsations at Zhongshan Station of Antarctica are analyzed from October 1 - 31, 1996. Their characteristics e.g. occurrence frequency, frequency, and polarization are studied. The characteristics of Pi2 pulsations are summarized as follows: (1) Pi2 pulsations at Zhongshan Station usually take place from 2000 MLT to 0200 MLT; the main frequencies are between 6.79 mHz and 13.58 mHz; (2) Pi2 pulsations with low frequencies are dominant. The range of main frequencies becomes narrow at midnight; (3) The polarization of Pi2 pulsations are almost linear; (4) About the orientation of major axes the NW-SE direction is dominant before 2200 MLT and NE-SW is dominant after 2200 MLT. The generation mechanism of Pi2 pulsations at Zhongshan Station is discussed theoretically.
