Fluctuations of high-energy electron fluxes in Earth's radiation belt and its applications for geomagnetic storm alert

  • 摘要: 地球磁场捕获带电粒子形成辐射带,地磁场的扰动将导致带电粒子通量的变化.根据磁暴期间外辐射带高能电子通量起伏和波动的特点及规律,利用GOES卫星实时发布的5min分辨率高能电子微分通量数据,构建了高能电子通量波动指数,并分析了该指数与地磁活动的关系.结果表明,所提出的高能电子通量波动指数与地磁事件有很好的相关性,能起到地磁暴发生的指示剂作用,相对于目前空间环境业务化预报过程中广泛使用的3hKp指数,高能电子通量波动指数能更早地警报地磁暴的发生,是潜在有效的地磁暴警报辅助手段,能为空间环境预报中的地磁暴实时警报提供重要参考.
