| 摘 要： | 利用IMAGE卫星FUV极光图像数据,对北半球极光椭圆带2760个亚暴事件进行统计分析,得到亚暴等待时间的统计分布,并利用简单的数学模型对卫星轨道的影响进行了讨论,得到以下结论:(1)亚暴等待时间在2-3h附近有一个峰值,较低纬度( MLat＜ 65°)发生的亚暴事件,其等待时间略长于较高纬度(MLat≥65°)发生的...

| Abstract: | This paper analyzes 2 760 substorm events in the Northern Hemisphere using observations made by the Far Ultraviolet Instrument onboard the IMAGE satellite to obtain the probability distribution of the substorm wait time(i.e.,the time interval between substorm onsets).The effects of the satellite orbit are taken in account.It is found that(1) the most probable substorm wait time is between 2 and 3 hours.The wait time is longer for substorms occurring at lower latitudes than those occurring at higher latitude... |
