Evolvement of the Ring Current During a Magnetic Storm: TC-2 Neutral Atom Imager Observations
Shen, Chao; Liu, Zhen-Xing; Lu, Li +3 more
A series of ENA images were obtained by the NUADU instrument aboard TC-2 during a strong, long duration magnetic storm that occurred in November 2004. This paper follows the evolution of the ring current during this magnetic storm. It is shown that the southward IMF Bz component plays a key role in facilitating ion injection from the magnetotail i…
ULF Waves Associated with Periodical High Speed Flows in the Magnetotail Plasma Sheet
Cao, Jin-Bin; Wang, Zhi-Qiang
In this paper, using the data of Cluster satellites on 8 November 2004, we analyze the ULF waves associated with earthward periodical high speed flows in the magnetotail plasma sheet. The results show that the ULF waves in the magnetic field and temperature appear, enhance and end at the same times with those of periodical high speed ion flows. Pa…
Mid-Tail Magnetic Reconnection Triggering Substorm: A Case Study
Luo, Hao; Wang, Rong-Sheng; Du, Ai-Min +2 more
Onset of a substorm is closely correlated with the current disruption in the near-Earth magnetotail, about 6 8 RE and magnetic reconnection in the middle magnetotail, around 20 30 RE. It is vital to understand the onset of a substorm by studying the time series among polar expansion of aurora, current disruption and magnetic reconnection. In this …
