Properties of the sunspot scar in the positive polarity of “Simulation 2”, shown by the 2D images (left half) and 1D plots of slit crossing through the scar (right half). Left half: Distributions of vertical magnetic field strength (B_z), horizontal magnetic field strength (B_h), inclination angle (angle), vertical current density (J_z), mass density (rho), and temperature (T) on the plane z = 0.1 at t = 67 in “Simulation 2.” The red (or green) solid (or dashed) contours outline the QSL footprints on this plane. Right half: 1D plots along the slit crossing through the sunspot scar at t = 67 (orange and blue dashed lines in the left half). From the top to the bottom, they are squashing degree (logQ), total magnetic field strength (|B|), horizontal magnetic field strength (B_h), vertical magnetic field strength (B_z), inclination angle, total current density (|J|), vertical current density (J_z), temperature (T), and mass density (rho). The red dashed line shows the peak of logQ, and the pink dashed lines demonstrate the range of the QSL footprint (logQ ≥ 3). The black vertical dashed line marks the dip of B_z in the sunspot scar. The black horizontal dashed line in the fourth row marks the value where the current density equals zero. A movie of this figure is available online.
