Longitudinal Variations of Total Ion Density in the Topside Ionosphere

  • 摘要: 利用DMSP F13卫星1996-2005年共10年的观测数据,研究地磁中低纬地区黄昏时段(18:00 LT)顶部电离层总离子密度经度变化的季节、地磁纬度和太阳活动变化特征.结果表明总的经度变化在低纬地区与中纬地区具有明显不同特征.不同经度结构的季节变化均以年变化为主,但纬度分布具有明显差异.一波结构主要集中在中纬地区,且南半球明显强于北半球;二波结构南北半球不对称性非常明显;三波结构和四波结构均为低纬地区明显强于中纬地区.通过分析不同波结构对总经度变化的贡献发现,一波结构在南半球中纬地区贡献最大,二波结构在12月前后的15°N附近贡献较大,三波结构和四波结构仅在低纬地区有较强贡献.在不同太阳活动条件下,不同波结构的贡献率有明显变化.
