巨行星磁盘的动力学受到行星自转的强烈影响。然而，太阳风最终必须将等离子体从这些快速旋转的磁碟中移除，其速度与等离子体从源区域（木卫一和土卫二等离子体环面）径向向外传输的速度相同。目前尚不清楚，当磁层动力学以自转为主时，太阳风是如何影响磁层动力学的。然而，极光观测提供了重要的线索。我们回顾了磁碟源和径向输运以及太阳风与木星和土星巨磁层的相互作用，试图将极光特征与特定的驱动因素联系起来。我们讨论了与太阳风相互作用有关的极光特征，并总结了全球磁层动力学的讨论，如全球MHD模拟所示。许多问题仍然存在，这篇综述的目的是强调未来研究中最引人注目的几个问题。
The dynamics of the giant planet magnetodiscs are strongly influenced by planetary rotation. Yet the solar wind must ultimately remove plasma from these rapidly rotating magnetodiscs at the same rate that plasma is transported radially outward from the source regions: the Io and Enceladus plasma tori. It is not clear how the solar wind influences magnetospheric dynamics when the dynamics are dominated by rotation. However, auroral observations provide important clues. We review magnetodisc sources and radial transport and the solar wind interaction with the giant magnetospheres of Jupiter and Saturn in an attempt to connect auroral features with specific drivers. We provide a discussion of auroral signatures that are related to the solar wind interaction and summarize with a discussion of global magnetospheric dynamics as illustrated by global MHD simulations. Many questions remain and it is the intent of this review to highlight several of the most compelling questions for future research.
