The whistler-mode signals transmitted from a Decca station in Japan and measured at the magnetic conjugate point in Australia usually reveal frequency shifts: a dusk positive shift (less than 0.5 Hz) and a dawn negative shift (greater than -0.5 Hz), independent of magnetic activity. The Doppler shift may be caused by a combination effect of the electron density variation of a field-aligned whistler duct with downward (upward) electron flux and the drift of the whistler ducts due to westward (eastward) equatorial electric fields generated by an ionospheric dynamo process around sunset (sunrise), respectively. The occurrence (total duration per day) of the whistler-mode signal indicates the highest correlation with the magnetic activity 1 day prior to the occurrence.
