The Appleton anomaly is caused by the upward E x B drift of the equatorial ionospheric plasma and subsequent diffusion along magnetic field lines to lower altitudes at higher latitudes. The strength and location of the Appleton anomaly has been thought to be controlled mainly by the interaction of the neutral winds with the electric and magnetic fields. Variability can arise from different geophysical processes affecting the neutral dynamics and the background electric/magnetic fields. In addition, ion drag from the differing densities between the two peaks of the anomaly can induce hemispheric differences in the zonal wind circulation. Recent global observations of the low latitude ionospheric structure revealed by TIMED/GUVI, TOPEX, and DMSP allow us to investigate the interplay between the neutral, plasma, and background fields. In this paper we will examine both satellite and groundbased measurements and interpret the findings using a global thermospheric/ionospheric model.
