[1] 地球磁层顶发生两种类型的重联：分量重联和反平行重联。最近，开发了一种经验模型，据称可以确定在什么太阳风条件下，一种或另一种类型的重新连接占主导地位。这个经验模型是利用星团航天器在磁层顶的观测结果进行测试的。对于一系列行星际磁场方向，磁层顶上存在一些区域，可以通过在磁层顶边界层中观察到的重联喷流的流动方向来区分这两种类型的重联。在这些特定行星际磁场（IMF）方向下的磁层顶的星团航天器观测证实了重联类型的模型预测。此外，这些观察结果表明磁层顶可能发生多重重联（分量重联和反平行重联）。
[1] Two types of reconnection occur at the Earth's magnetopause: component and antiparallel reconnection. Recently, an empirical model was developed that purportedly determines under what solar wind conditions one or the other type of reconnection is dominant. This empirical model is tested using observations at the magnetopause from the Cluster spacecraft. For a range of interplanetary magnetic field orientations, there are regions on the magnetopause where these two types of reconnection can be distinguished from one another by the direction of the flow of reconnection jets observed in magnetopause boundary layers. Cluster spacecraft observations at the magnetopause under these specific interplanetary magnetic field (IMF) orientations confirm model predictions of the type of reconnection. In addition, these observations show evidence of possible multiple reconnection (both component and antiparallel) occurring at the magnetopause.
