论文摘要
本文介绍了赤道电离层对2000-2005期间发生的十一强的地磁风暴的赤道电离响应，即太阳周期的下降阶段。观察结果表明，在大约91％的情况下，从北向向南到向南过渡的行星际磁场（IMF）时钟角度发生在3H内发生，从而使IMF在迅速渗透（PPEF）的过程中发挥了IMF的重要性，此外还引起了IMF（PPEF）的重要性。这是从先前报道的（Ray等人，2015）4H窗口的改进，ESF从南部IMF BZ越过-10 nt。
This paper presents the equatorial ionospheric response to eleven strong-to-severe geomagnetic storms that occurred during the period 2000-2005, the declining phase of the solar cycle 23. The analysis has been performed using the global ion density plots of Defense Meteorological Satellite Program (DMSP). Observations show that for about 91% of the cases, post-sunset equatorial irregularities occurred within 3h from the time of northward to southward transition of the Interplanetary Magnetic Field (IMF) clock angle, thus bringing out the importance of the role played by IMF By in the process of Prompt Penetration of Electric Field (PPEF) in addition to the IMF Bz. This is an improvement from the previously reported (Ray et al.,2015) 4h window of ESF generation from the southward IMF Bz crossing -10 nT.
