There is a marked day to day variability in the magnitude of the drift speed which is well correlated with the electrojet strength. Counter-electrojet events are maximum during J-solstices and minimum during equinoxes. Drift speeds are also shown to decrease linearly with increasing K index and with increasing southward component of the interplanetary magnetic field. Small changes due to lunar tidal effects are also isolated.
