Figure 9.

Schematics showing the main observational characteristics of (a) the field‐aligned current (FAC) events (i) and (ii) and (b) the FAC events (iii) and (iv) and the ion‐scale thin (Hall) current layers flowing duskward (red) and dawnward (light green). FAC directions are given by the black arrows. The dotted arrow shows the spacecraft motion relative to the current sheet; that is, the motion of the current sheet itself is outward for the events (i) and (ii) and inward for events (iii) and (iv). The ion bulk flow is given in blue arrows, while the purple represents the electric field direction. The light yellow color in (b) represents region with tailward cold ion beams.
