摘　　要：Cluster/HIA 和 Cluster/FGM 在 2001 -2003 从 7 月在时期期间测量到 10 月的血浆表十字路口上的数据被分析。在连续脑叶的典型特征上基于以前的工作重新连接在参考，二案例研究和统计分析描述的离子(CLR ) 为发生在这个时期期间的事件在 midmagnetotail 和潜水艇暴风雨扩大发作在在 CLR 之间的关联上被执行。几乎所有 CLR 事件在有潜水艇暴风雨的靠近的连接，这被发现。CLR 的开始几乎总是是在在近的地球磁电机尾巴并且在基于 theground 的车站上看见的潜水艇暴风雨活动前的一些分钟。这提供 CLR 在连续向南方的星际间的磁场的时期期间是 substormexpansion 发作的虚拟原因的一个清楚的指示。Data on plasma sheet crossing measured by Cluster/HIA and Cluster/FGM during the period from July to October in 2001-2003 are analyzed. Based on previous work on the characteristic features of continuous lobe reconnection （CLR） described in reference, two case studies and a statistical analysis were carried out on correlation between CLR in the mid magnetotail and substorm expansion onset for the events occurring during this period. It is found that almost all CLR events are in close connection with substorms. The beginning of CLR is almost always a few minutes ahead of substorm activities seen in the near Earth magnetotail and on the ground-based stations. This provides a clear indication that CLR is the virtual cause of substorm expansion onset during the period of continuous southward interplanetary magnetic field.
