Base simulation results showing the CME evolution in equatorial (left) and meridional (right) planes. Panels (a–d) display the magnetic field component B_z (nT). Panels (e–h) display the radial velocity Vr (km/s), at 2022-03-12 09:59 UT (a–b, e–f) and 2022-03-13 19:59 UT (c–d, g–h). Left panels (a, c, e, g) show a top-down view of the CME propagation on the equatorial plane, while the right-hand panels (b, d, f, h) show the meridional plane, giving a side-on view of its vertical extent and latitudinal structure. The concentric circles indicate heliocentric distance contours and serve as radial reference markers.
