A large scale 3D global full particle simulation of the solar wind-terrestrial magnetosphere interaction: Impact of the IMF rotation on the magnetospheric cusp dynamics

In the present paper, to our knowledge, the first 3D global full electro-magnetic particle simulation in the global view of solar-wind-magnetosphere interaction are performed, and compared with the statistical surveys of the plasma flows measured by the Cluster spacecraft in the high-altitude cusp region of the Northern Hemisphere. The magnetospheric polar cusp regions are considered to be key regions to transfer mass, and energy from the solar-wind to the plasma sheet. Using the global PIC simulation, we try to understand these key regions and the dynamical interactions that occur there. The basic structures of the so-called stagnant cusp exterior (SEC) are observed in the simulation. The sub-Alfvenic layers which consider to be the plasma depletion layer (PDL) are observed. The 3D PIC simulation reveals the global views of the solar-wind magnetosphere interactions and the magnetic polar cusp structures.
