Overview of the north–south asymmetric transport of the polar outflows during a typical northward IMF condition, under the influences of a B_x component. The white (pink) arrows are the representation of the flows outside (inside) the magnetopause. The length of the arrows denotes the velocity magnitude. In contrast, the length of the arrow in the left-most part of the figure (in the solar wind) denotes 400 km s⁻¹. The background colors represent the plasma flux in the noon–midnight plane.
