The middle panel shows the variations in the mean of the superposed values of 18 cases (on 18 days) of AE decay that occurred just prior to sunset during the period October, November, and December 2003. The top panel shows the corresponding mean variation in the Sym-H/Dst values, and the bottom panel shows the corresponding variation in the vertical drift velocity (pink curve) and the mean of ten quiet days of vertical drift (blue curve), demonstrating the PRE vertical drift suppression due to over-shielding westward electric field
