Abstract:

利用1997-2007年由GOES8,GOES11和GOES12星载高能粒子探测器在地球同步轨道高度上所探测到的高能质子和高能电子通量探测数据以及高度560km左右星载大气密度探测器所得的热层大气密度探测数据,统计分析了强地磁扰动、高能粒子通量跃变和热层大气密度涨落之间的相关关系,初步获得强地磁扰动期间,地球同步轨道(外辐射带外环)均出现了增幅大于三个数量级的高能质子通量(尤其是E>1MeV)强增强现象,随后热层大气密度强烈上涨,表明三者之间是正相关关系.在时间上地球同步轨道高能质子通量强增强现象先于日均Ap值(地磁活动程度)上涨约一天左右,而热层大气密度强涨落现象又明显滞后于强地磁扰动事件.
