| 摘 要： | 利用2010年11月至2011年10月IGS提供的全球电子浓度总含量(TEC)数据, 分析太阳活动上升期华南地区(经度110°E, 纬度5°—35°N) 上空电离层赤道异常(EIA)北驼峰的变化特征. 结果显示, 电离层赤道异常北驼峰区TEC峰值I具有明显的季节和半年变化特征; 北驼峰峰值出现的时间T和纬度L的日变化有一个相对较大的变化区间, 其季节和半年变化特征并不明显; 太阳活动对北驼峰变化影响比较明显, 而地磁活动对北驼峰变化影响不明显.

| 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. |
