对2001年7月~10月Cluster穿越磁尾等离子体片边界层期间观测到的172个场向电流事件进行了研究,主要分析了等离子体片边界层场向电流特性与地磁活动指数之间的关系。研究结果表明:1)等离子体片边界层场向电流的相对发生率随地磁活动的增强而增加;2)等离子体片边界层场向电流密度随Kp指数的增大而增大;在磁暴的主相阶段,场向电流迅速增大,电流密度最大达到19.05nA/m~2,同时Kp增大至5;3)地磁活动指数Kp与等离子体片边界层区场向电流密度有着一致的变化关系.然而,当AE<800nT时,等离子体片边界层场向电流密度随着AE的增加而增加,当AE>800nT时,场向电流密度随着AE的增加而减小.从而说明,等离子体片边界层场向电流密度与Kp指数的变化关系更为密切. |
