  1. 1. Possible Bow Shock Current Closure to Earth's High Latitude Ionosphere on Open Field Lines

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Nyckelord :Space Physics; Bow Shock Current; Field-Aligned Currents; Open Field Lines;

    Sammanfattning : The bow shock is formed due to the abrupt deceleration of the supersonic solar wind in front of the terrestrial magnetic field. The solar wind plasma and the Interplanetary Magnetic Field (IMF) are both compressed across the shock, and according to Ampère's law a current thus flows on the bow shock at all times. LÄS MER

  2. 2. Bow shock current closure to Earth's polar ionosphere - A statistical study using AMPERE and OMNI data

    Kandidat-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Eva Krämer; [2021]
    Nyckelord :;

    Sammanfattning : The bow shock current is hypothesized to connect to the Earth's magnetosphere on open field lines and to contribute as a field aligned current to the polar ionospheric currents. In order to investigate this, two years of AMPERE data are used to compute the average region 1 currents, and average currents within the polar cap boundary, under different interplanetary magnetic field (IMF) clock angles and IMF magnitudes.
