在探测土星磁尾的过程中，卡西尼磁力计探测到了许多磁场重联的现场例子，如等离子体团、移动压缩区（TCR）和偶极。与此同时，许多磁层现象已经被证明是由行星周期振荡系统组织的，这些系统分别来自行星的北方和南半球。在这里，我们研究之间的关系，发生的等离子体团和TCR和磁场相位的北方和南方系统。我们发现，事件在北方和南方阶段的组织程度令人震惊，事件优先与磁层等离子体和场线从行星向外移位以及电流片变薄的间隔有关，这两种效应都可能有利于发生重连和等离子体相关的质量损失。几乎没有证据表明等离子体片的南北运动会产生显著的能见度效应。
During its exploration of Saturn's magnetotail the Cassini magnetometer has detected many in situ examples of magnetic reconnection, in the form of plasmoids, traveling compression regions (TCRs), and dipolarizations. Meanwhile, many magnetospheric phenomena have been shown to be organized with particular regularity by planetary period oscillation systems driven separately from the Northern and Southern Hemispheres of the planet. Here we examine the relationship between the occurrence of plasmoids and TCRs and the magnetic phases of the northern and southern systems. We find a striking degree of organization of the events by both northern and southern phases, with events linked preferentially to intervals in which the magnetospheric plasma and field lines are displaced outward from the planet and the current sheet thinned, both effects being likely to favor the occurrence of reconnection and plasmoid‐related mass loss. Little evidence is found for significant visibility effects associated with north‐south motions of the plasma sheet.
