英文摘要The equatorial ring current (ERC) theory suggested that the distribution of global disturbed horizontal geomagnetic field only depends on the cosine of station's latitude. However, we always observe a larger. H at higher latitude stations than lower ones, implying that the ERC could tilt or/and shift with respect to the equatorial plane during intense storms. In this paper, we analyze 11 intense magnetic storms from 2000 to 2004, and introduce two configurational factors to characterize the topology of storm time ring current. The results show that ERC has occasionally deviated off equatorial plane with both tilt angle delta(t)approximate to 13 degrees-25 degrees and latitude shift delta(t)approximate to 0 degrees-21.8 degrees. The ground disturbed field distribution should be improved as Delta H(kappa) =Delta H(max)cos(phi(kappa)-delta), which agree well with the geomagnetic observations.
