Schematic of the coupling mechanism between high-latitude SAPS and the equatorial electrojet

Caption

A conceptual diagram demonstrating how subauroral polarization streams (SAPS, right panel) in the subauroral region generate electric fields that map along Earth's magnetic field lines, establishing a vertical polarization electric field in the equatorial ionosphere to modulate the daytime equatorial electrojet (EEJ, left panel).
