Combined Particle and Fluid Simulations of the Magnetosphere, Its Boundary Layers and Current Systems

该提案描述了全球磁层多流体模拟模型的进一步发展。 有人建议，该模型将允许一个明确的过程，允许太阳风等离子体进入磁层，磁层等离子体泄漏到太阳风，和流出的电离层等离子体进入遥远的磁层。 初步结果表明，通过低纬边界层和高纬重联向北IMF和通过地幔和昼侧重联向南IMF的入口等离子体成分之间的空间分布有明显的差异。 将对特定的个案研究与现场观测进行比较，以进行模型验证研究。

This proposal describes the further development of a multi-fluid simulation model of the global magnetosphere. It is proposed that the model will allow a clear identification of processes which permit entry of solar wind plasma into the magnetosphere, the leakage of magnetospheric plasma into the solar wind, and the outflow of energized ionospheric plasma into the distant magnetosphere. Preliminary results show clear differences in the spatial distributions between plasma components with entry via the low latitude boundary layer and high latitude reconnection for northward IMF and via the mantle and dayside reconnection for southward IMF. Comparison with in-situ observations will be undertaken for particular case studies to perform model validation studies.
