论文摘要
在准航空星际磁场（IMF）下，前锁湍流可能会对磁石产生影响，并取决于准平行冲击的位置。我们使用混合代码高度对地球日期磁层进行三维模拟，并比较北向和南方的准界IMF构型。我们研究磁场构型，磁石中的波动以及北部尖尖的区域的血浆。在带有Earthward $ b_x $的北部IMF下，在北部尖口外面有一个时变的等离子体耗竭层。在南向IMF的情况下，前锁湍流和高速喷射的影响以及磁笼重新连接可能会导致尖尖的强度增强。
Under quasi-radial interplanetary magnetic fields (IMF), foreshock turbulence can have an impact on the magnetosheath and cusps depending on the location of the quasi-parallel shock. We perform three-dimensional simulations of Earth's dayside magnetosphere using the hybrid code HYPERS, and compare northward and southward quasi-radial IMF configurations. We study the magnetic field configuration, fluctuations in the magnetosheath and the plasma in the regions around the northern cusp. Under northward IMF with Earthward $B_x$, there is a time-varying plasma depletion layer immediately outside the northern cusp. In the southward IMF case, the impact of foreshock turbulence and high-speed jets, together with magnetopause reconnection, can lead to strong density enhancements in the cusp.
