1. IntroductionThe subauroral polarization stream (SAPS) is an interesting and important phenomenon in the subauroral region and is characterized by rapid sunward plasma flow [1]. The SAPS is intrinsically related to the midlatitude trough [2,3], region-2 field-aligned currents (R2 FACs) and the location of the plasmapause. In addition, the SAPS plays a very important role in the injection and energization of plasma in the inner magnetosphere [4,5].
