Investigation of the macroscopic variation in a heliospheric termination shock

The main purpose of this research is to investigate the dynamic evolution of the solar wind structure in the heliosphere, which will results in the non-uniform and non-stationary variation in the termination shock. Special attention is paid to the energetic processes occurred inside the heliosphere, where the upstream conditions for the termination shock are determined. Numerical simulation results show that the shock properties are largely modulated by the interaction with large-amplitude disturbances in the heliospheric electromagnetic field as well as the presence of non-solar origin particles.
