Gas-dynamic interpretation of the ion density variations in the magnetosheath: Comparison with cluster data
Abstract
The purpose of this research is to investigate the wide range of ion density variations in the magnetosheath. In an attempt to explain these variations the numerical magnetosheath-magnetosphere model is applied. The gas-dynamic theory describes the plasma characteristics in the magnetosheath, while in the magnetosphere a numerical magnetospheric magnetic field model is adopted. ACE spacecraft measurements are used as a solar wind monitor. The considered event of Cluster satellite passing through the magnetosheath is connected with strong ion density variation along the satellite trajectory. The results of 3D numerical modeling, presented in this paper, confirm that such variations are well represented in the frame of gas-dynamics.
