Abstract:

From the observed aurora and corresponding disturbances of geomagnetic field,we get the distribution law and its intensity of auroral electrojet near Antarctica Zhongshan Station (AZS) described by AU AL and AE indexes. We found that the intensity of east component of auroral electrojet is positive, and the west is negative. As absolute value is concerned, the west component is greater than the east. The intensity of auroral electrojet in summer is greater than that in winter around AZS. The simulation curve of the distribution law of east component in the seasons of summer autumn and winter is like a up parabola curve between 720 and 1440 min(UT 12-24 hour). And that of the west is just like a sine wave curve. The distribution characteristic of auroral electrojet in AZS, is helpful for the studies of F layer and magnetosphere coupling in polar region and aurora dynamics.
