Different configurations of the EEJ longitudinal structures. In the top panel, the EEJ longitudinal profiles with three main maxima corresponding to December solstice are shown. The middle panel shows the wave-four patterns the EEJ longitude profiles in the transition phases during March, April, May and October. The bottom panel exhibits well-established wave-four patterns from June to September. L1, L2, L3, L4 and L5 and plus symbol indicate the locations of various maxima
