WebOct 12, 2016 · Such shocks are generated when the solar wind slams into Earth’s magnetic field, undergoing a sudden slowdown. Bow shocks occur outside Earth’s magnetosphere, and therefore beyond the orbit of MMS. But a fluctuation in the solar wind can temporarily compress the magnetosphere, leaving the MMS spacecraft in the path of a bow shock. WebThe position and shape of the bow shock depend on the ram pressure. Alfven and sonic Mach numbers, and the angle between the solar wind velocity and magnetic field in the solar wind. This can be seen by writing down the MHD equations in conservative form and then manipulating them. In conservative form the MHD equations can be written: and.
