1997年1月6—11日日地连接事件──对磁暴-环电流-对流电场的讨论

THE SUN-EARTH CONNECTION EVENT OF JANUARY 6-11, 1997

给出了1997年1月6—11日日地连接事件的太阳风和行星际扰动及由此产生的地磁扰动特征．利用这些资料对磁暴-环电流-对流电场的分析表明，磁暴主相（或环电流）的开始主要是IMF南向分量形成的对流电场直接驱动的结果；对流电场在磁暴主相的形成中有极为重要的作用；

The Paper presents the features of disturbances of solar wind and interplanetary as well as the magnetic storm recorded at the geomagnetic network in China during the Sun-Earth connection event of January 6-11, 1997. The magnetic storm-rin currentconvection electic fields are sturdied using the data. Results show that the beginning of the main phase is formed maily by convection electric field driven by IMF Bs. The convection electric fields play very important roles during the main phase evolution, but the effects are different at different stages.
