英文摘要Instances of multiple excitation of large-scale gravity waves in the auroral region by solar wind Alfvenic fluctuations are rare. In this paper we report an unusual instance, in which sequential large-scale gravity waves launched from northern and southern auroral regions are clearly linked to intermittent southward magnetic fields of Alfvenic fluctuations embedded in three successive stream interaction regions. The continuous gravity wave activity persists for similar to 7 days, the longest duration currently tracked. The Alfvenic fluctuations are mainly dominated by Alfven and slow waves, which might play a role in the solar wind-magnetosphere interaction, leading to impulsive auroral electrojet activity and in turn exciting the sequential gravity waves.
