This project will compare and contrast the magnetospheres of the Earth, Jupiter and its satellite, Ganymede. The study will provide a theoretical framework for understanding the roles that are played by the different sizes and rotation rates of the three objects. The project will involve analytic theory, data analysis and numerical simulations using a magnetohydrodynamic (MHD) code. One of the important issues to be addressed is the role of magnetic flux tube interchange, which has been observed in Jupiter's magnetosphere but may or may not play a role in the Earth's magnetosphere.

该项目将比较和对比地球、木星及其卫星木卫三的磁层。 该研究将为理解这三个物体的不同大小和旋转速率所扮演的角色提供一个理论框架。 该项目将涉及分析理论，数据分析和数值模拟使用磁流体动力学（MHD）代码。 需要解决的一个重要问题是磁通量管交换的作用，这种交换在木星的磁层中已经观察到，但在地球的磁层中可能会或可能不会发挥作用。
