The basic driver for the magnetosphere is the solar wind (dynamic pressure and magnetic field). However, it is becoming increasing clear that the nature of the driving mechanism is significantly altered by processes in the bow shock and magnetosheath. Observational evidence from both satellites and ground-based instruments have shown this to be true, but surprisingly little theoretical/modeling work has been done on this subject. The proposed research program will use three-dimensional MHD modeling and two-dimensional Hybrid modeling to address these problems.

磁层的基本驱动力是太阳风（动态压力和磁场）。 然而，越来越清楚的是，驱动机制的性质显着改变的过程中的弓形激波和磁鞘。 来自卫星和地面仪器的观测证据表明这是真的，但令人惊讶的是，在这个问题上几乎没有做过理论/建模工作。 拟议的研究计划将使用三维MHD建模和二维混合建模来解决这些问题。
