3D perspective (as viewed from the north near the dawnside flank) of the structure of a plasmoid formed under southward IMF condition (at T = 90 h). Color traces are sampled field lines extracted from the simulation with green showing field lines that thread the plasmoid and magenta showing field lines that surround the plasmoid. The background colors represent contours of Bz. The two dashed lines show the bow shock and magnetopause boundaries identified by tracing flow streamlines. The orange balls mark every 10 RS along the axes.
A 3D perspective from a viewpoint above the equator in the noon meridian plane of the flux tubes returning from tail reconnection site to the magnetosphere as seen in the simulation at T = 225 h. Plotted in the equatorial plane are color contours of Vphi/Vcor overlaid with line contours of plasma density. The pattern of field-aligned currents along with unit flow vectors color coded with Vphi/Vcor in the northern ionosphere are shown in the inset as well as in the magnetospheric plot (mapped to a sphere of radius 4 RS for clarity). Green traces show some sampled field lines traced through the region of rapidly moving flows in the magnetosphere.
A snapshot of global convection and the distribution of flux tube content extracted from the simulation at a time (T = 482 h) when the IMF is northward. The background color contours represent the horizontal flow velocity (Vx) according to the bottom-right color bar and the color contours on a circular disk surrounding Saturn represent FACs intensity in the northern ionosphere (mapped to 4 RS) according to the top-right color bar. The intersections of sampled closed field lines with the equatorial plane are plotted as balls color coded with their corresponding flux tube content (according to the bottom-left color bar). Also plotted are unit flow vectors of the closed field lines showing the direction of their motion. The orange traces show some representative field lines that form the axes.
