    Abstract
  • Variation of the Equatorial Ionospheric Anomaly (EIA) crest over South China region during the solar activity increasing periods is analyzed using the Total Electron Content (TEC) data from International GPS Service (IGS) between November 2010 and October 2011. The variation of the EIA crest in TEC shows an obvious seasonal and semiannual variation. Locations of the daily EIA crest have quite a large range of scatter in both universal time and latitude, but the similar seasonal or semiannual variation is not seen in the location of the anomaly crest. The variation of EIA crest in TEC shows a very good correlation with the solar flux, but do not correlate well with the geomagnetic activity.
