我们报告的磁层重联多尺度观测薄电流片在接口的互联通量管进行会聚重联射流在地球的磁层顶。界面电流片的离子趋肤深度-尺度宽度和非冻结离子表明，磁层多尺度穿过离子扩散区，穿过X线附近的重联层。在这一事件和其他三个事件中，磁场重联分量在接近界面电流片时的显著堆积伴随着磁剪切的增加和Δβ的减小，导致有利于界面电流片处重联的条件。堆积还导致每个粒子的可用磁能增强和强电子加热。这些观测结果揭示了具有多个重联位点的3-D系统的演化和能量释放。
We report Magnetospheric Multiscale observations of reconnection in a thin current sheet at the interface of interlinked flux tubes carried by converging reconnection jets at Earth's magnetopause. The ion skin depth‐scale width of the interface current sheet and the non‐frozen‐in ions indicate that Magnetospheric Multiscale crossed the reconnection layer near the X‐line, through the ion diffusion region. Significant pileup of the reconnecting component of the magnetic field in this and three other events on approach to the interface current sheet was accompanied by an increase in magnetic shear and decrease in Δβ, leading to conditions favorable for reconnection at the interface current sheet. The pileup also led to enhanced available magnetic energy per particle and strong electron heating. The observations shed light on the evolution and energy release in 3‐D systems with multiple reconnection sites.
