Using synoptic magnetograms from the National Solar Observatory/Kitt Peak spanning 19 February 1975, to 25 September 2003, we investigate the phase relationships among different types of magnetic elements at low and high solar latitudes. At low latitudes, the magnetic fields of sunspots and ephemeral regions significantly lead the network magnetic fields by approximately half a solar cycle. At high latitudes, conversely, the network magnetic fields lag the intranetwork magnetic fields (horizontal components) by a comparable half-cycle interval, also with statistical significance. In addition, the low-latitude magnetic fields of sunspots and ephemeral regions significantly lead the high-latitude network magnetic fields by about half a solar cycle. We offer a plausible physical interpretation for these observed phase relationships. These systematic phase offsets suggest a common underlying transport mechanism connecting the equatorial and polar magnetic fields.
