    • Comparison study of ring current simulations with and without bubble injections 

      Yang, Jian; Toffoletto, Frank R.; Wolf, Richard A. (2016)
      For many years, stand-alone ring current models have been successfully producing storm time ring current enhancements without specifying explicit localized transient injections along their outer boundaries. However, both ...
    • The Harang reversal and the interchange stability of the magnetotail 

      Ohtani, Shinichi; Gkioulidou, Matina; Wang, Chih-Ping; Wolf, Richard A. (2016)
      The present study addresses steady convection in the plasma sheet in terms of the interchange stability with special attention to the Harang reversal. The closure of the tail current with a field-aligned current (FAC) ...
    • On the contribution of plasma sheet bubbles to the storm time ring current 

      Yang, Jian; Toffoletto, Frank R.; Wolf, Richard A.; Sazykin, Stanislav (2015)
      Particle injections occur frequently inside 10 Re during geomagnetic storms. They are commonly associated with bursty bulk flows or plasma sheet bubbles transported from the tail to the inner magnetosphere. Although ...
    • RCM-E simulation of a thin arc preceded by a north-south-aligned auroral streamer 

      Yang, Jian; Toffoletto, Frank R.; Wolf, Richard A. (2014)
      The Time History of Events and Macroscale Interactions during Substorms (THEMIS) all-sky imager data have recently revealed a repeatable sequence that occurs during many auroral substorms, in which a newly formed thin arc ...
    • RCM-E simulation of bimodal transport in the plasma sheet 

      Yang, Jian; Wolf, Richard A.; Toffoletto, Frank R.; Sazykin, Stanislav; Wang, Chih-Ping (2014)
      Plasma sheet transport is bimodal, consisting of both large-scale adiabatic convection and intermittent bursty flows in both earthward and tailward directions. We present two comparison simulations with the Rice Convection ...
    • RCM-E simulation of substorm growth phase arc associated with large-scale adiabatic convection 

      Yang, Jian; Wolf, Richard A.; Toffoletto, Frank R.; Sazykin, Stanislav (2013)
      [1] Substorm auroral breakup often occurs on a longitudinally elongated arc at the end of a growth phase. We present an idealized high-resolution simulation with the Rice Convection Model-Equilibrium (RCM-E) to investigate ...
