This work will investigate the details of how the plasma transported by the solar wind interacts with the plasma inside the magnetosphere near the dayside magnetopause. The study will use semi-global, three-dimensional hybrid simulations in which the electrons are treated using a fluid approximation, but the ions are treated using a kinetic particle description. The 3-D simulations will provide a study of the magnetopause with more realistic boundaries than have been studied in the past. Shear flow, curvature of the boundary, and coupling of boundaries and the motion of boundaries will all be included. The regions of study will include the bow shock, the magnetosheath and the magnetopause.

这项工作将研究太阳风输送的等离子体如何与日侧磁层顶附近磁层内的等离子体相互作用的细节。这项研究将使用半全局三维混合模拟，其中电子使用流体近似处理，但离子使用动力学粒子描述处理。三维模拟将为磁层顶的研究提供比过去研究更真实的边界。剪切流、边界的曲率以及边界和边界运动的耦合都将包括在内。研究区域将包括弓形激波、磁鞘和磁层顶。
