| 摘 要： | 本文考察了远东地区电离层Es的增强与地磁活动的关系.因采用了时间迭加法和地方磁情指数K,且着重于夜间和变化幅度较大的Es,所以所得结果特征显著.以本文所用的1213次Es增强事件,70%左右的夜间Es在增强前11小时内有K≥4或△K≥2;另外30%左右的夜间Es增加,或出现于磁静日,且与邻近的印度海德拉巴地磁台所记录到的缓始磁暴有关;或发生在全球性大磁暴前.

| Abstract: | The relationship between the enhancement events of ionospheric Es in the Far Bast region of the world and geomagnetic activity is examined. The approach adopted in this paper is to use local geomagnetic index K in the superposed epoch analysis and special emphasis is put on the night time Es echoes with large amplitudes of variations, so that some remarkable results may be expected. Among 1213 enhanced Es events analysed in this paper, about 70% is accompanied by the conditions of L>4 or K>2 within 11 hours before the event. The remaining enhanced Es, either occurred on geomagnetic quiet days and seems to be associated with some gradual commencement storms occurring in neigboring Hyderabad, India, or occurred before certain large geomagnetic storms. |
