对2003年10月29日、10月30日两个典型大磁暴进行了分析,研究了磁暴期间磁场变化率与地电场的关系,以及磁暴期间磁暴、磁场变化率及地电场的周期成分。结果表明,磁暴期间H分量变化率与地电场东向分量观测数据显著相关,并且周期成分相同。
In this paper, the geomagnetic storms on October 29 and October 30, 2003 were analyzed, and the relation between geomagnetic storm change rate and geoelectric field was studied. The result shows, the H component of geomagnetic storm change rate and the geoelectric field east recorded are remarkable relevant, and have the same periodic components.
