The Dst index has been one of the most important solar-terrestrial indices for decades, and it is used in numerous studies as a measure of the temporal development and intensity of magnetic storms and...
对NOAA的POES系列极轨卫星观测得到的1978年以来近30年的极光沉降粒子半球能量的估算值EPI(Estimated Power Input)数据进行了分析，结果表明，极光沉降粒子有显著的春秋分峰值的年变化特征，并且有冬季半球沉降能量较大的南北半球不对称性.对EPI的时均值Pa与地磁指数AE、Dst的相关分析得到，Pa与AE的相关系数为0.76，Pa与Dst的相关系数为-0.55.把南北半球的...
