      Zhang, Qing-He; Zhang, Yong-Liang; Wang, Chi; Lockwood, Michael; Yang, Hui-Gen; Tang, Bin-Bin; Xing, Zan-Yang; Oksavik, Kjellmar; Lyons, Larry R.; Ma, Yu-Zhang; Zong, Qiu-Gang; Moen, Jøran Idar; Xia, Li-Dong (Journal article; Peer reviewed, 2020)
      A distinct class of aurora, called transpolar auroral arc (TPA) (in some cases called “theta” aurora), appears in the extremely high-latitude ionosphere of the Earth when interplanetary magnetic field (IMF) is northward. ...
    • Quantification of Cold-Ion Beams in a Magnetic Reconnection Jet 

      Li, Yu-Xuan; Li, Wen-Ya; Tang, Bin-Bin; Norgren, C.; He, Jian-Sen; Wang, Chi; Zong, Qiu-Gang; Toledo-Redondo, S.; André, M.; Chappell, C.; Dargent, J.; Fuselier, S.A.; Glocer, A.; Graham, D.B.; Haaland, S.; Kistler, L.; Lavraud, B.; Moore, T.E.; Tenfjord, P.; Vines, S.K.; Burch, J. (Journal article; Peer reviewed, 2021)
      Cold (few eV) ions of ionospheric origin are widely observed in the lobe region of Earth’s magnetotail and can enter the ion jet region after magnetic reconnection is triggered in the magnetotail. Here, we investigate a ...
    • A space hurricane over the Earth’s polar ionosphere 

      Zhang, Qing-He; Zhang, Yong-Liang; Wang, Chi; Oksavik, Kjellmar; Lyons, Larry R.; Lockwood, Michael; Yang, Hui-Gen; Tang, Bin-Bin; Moen, Jøran Idar; Xing, Zan-Yang; Ma, Yu-Zhang; Wang, Xiang-Yu; Ning, Ya-Fei; Xia, Li-Dong (Journal article; Peer reviewed, 2021)
      In Earth’s low atmosphere, hurricanes are destructive due to their great size, strong spiral winds with shears, and intense rain/precipitation. However, disturbances resembling hurricanes have not been detected in Earth’s ...
    • Unusual shrinkage and reshaping of Earth’s magnetosphere under a strong northward interplanetary magnetic field 

      Wang, Xiang-Yu; Zhang, Qing-He; Wang, Chi; Zhang, Yong-Liang; Tang, Bin-Bin; Xing, Zan-Yang; Oksavik, Kjellmar; Lyons, Larry R.; Lockwood, Michael; Zong, Qiu-Gang; Li, Guo-Jun; Liu, Jing; Ma, Yu-Zhang; Wang, Yong (Journal article; Peer reviewed, 2023)
      The Earth’s magnetosphere is the region of space where plasma behavior is dominated by the geomagnetic field. It has a long tail typically extending hundreds of Earth radii (RE) with plentiful open magnetic fluxes threading ...
