Virtual Height Variation during Plasma Bubble Evolution Associated with Plasma Blob in Low Latitude Ionosphere

  • 摘要:

    针对东亚地区地磁低纬度南北半球Vanimo台站(地理2.7°S,141.3°E;地磁 11.2°S,146.2°W)和海南台站(地理19.5°N,109.1°E;地磁9.1°N,179.1°W)上空的3个电离层等离子体块与等离子体泡相关联的事件,利用地面台站的电离层测高仪连续观测数据,研究等离子体泡演化期间的电离层虚高变化。结果表明:以往提出的等离子体块出现约2 h之前等离子体垂直漂移速度从向上(东向电场)转为向下(西向电场)的观点,本文的3个事例均与之不符,或者距反转时间很远(约6 h),或者由向下转为向上。在等离子体块形成时间点前的1 h内,均有突发的等离子体堆积的运动趋势,或是下降运动速度突然变慢,或是从下降转为向上运动,或是上升运动速度突然加快。这一堆积现象与等离子体块现象相关性更好,也不仅限于漂移速度从向上转变为向下。
