Anotace:
The Earth’s magnetic field creates a cavity in the solar wind. This cavity – the magnetosphere – is bounded by the magnetopause that is often treated as an impenetrable obstacle to the solar wind flow. Since the solar wind is highly supersonic, the bow shock is formed in front of the magnetopause. Interaction of the solar wind that carries frozen–in interplanetary magnetic field with the bow shock is strongly non-linear and depends on the IMF orientation. It decelerates and heats the solar wind plasma and diverts it around the magnetopause in a layer called the magnetosheath.
The goal of this study is to investigate these processes and to determine the role of the IMF orientation and its abrupt changes on (1) the creation of magnetosheath discontinuities and (2) interaction of these new discontinuities with the magnetopause. The study will be based on the multispacecraft observations of the interaction region and will be supported with the local and global MHD modeling.
