Relativistic-electron dropouts and recovery: A superposed epoch study of the magnetosphere and the solar wind [PDF]
, 2009 During 124 high-speed-stream-driven storms from two solar cycles, a multispacecraft average of the 1.1–1.5 MeV electron flux measured at geosynchronous orbit is examined to study global dropouts of the flux. Solar wind and magnetospheric measurements are

Probing the relationship between electromagnetic ion cyclotron waves and plasmaspheric plumes near geosynchronous orbit [PDF]
, 2010 Plasmaspheric plumes created during disturbed geomagnetic conditions have been suggested as a major cause of increased occurrences of electromagnetic ion cyclotron (EMIC) waves at these times.

Nonlinear wave growth theory of coherent hiss emissions in the plasmasphere [PDF]
Journal of Geophysical Research: Space Physics, 2015 AbstractRecent observations of plasmaspheric hiss emissions by the Van Allen Probes show that broadband hiss emissions in the plasmasphere comprise short‐time coherent elements with rising and falling tone frequencies. Based on nonlinear wave growth theory of whistler mode chorus emissions, we have examined the applicability of the nonlinear theory to ...

The interactions between ULF waves and cold charged particles in the Earth's magnetosphere
地球与行星物理论评, 2022 In the solar wind-magnetosphere coupling processes, many kinds of plasma waves can be excited in the Earth's magnetosphere including ULF waves, hiss waves, chorus waves, etc. Among these waves, ULF waves are featured by the lowest wave frequency (1 mHz～1

Plasmaspheric dynamics resulting from the hallowe'en 2003 geomagnetic storms [PDF]
, 2009 Cross-phase-derived plasma mass density trends during the Hallowe'en 2003 geomagnetic storms are presented for 38° magnetic latitude 63° (1.61 ≤ L ≤ 5.10), using data from the SAMNET (Subauroral Magnetometer Network), BGS (British Geological Survey), and

Modeling the properties of plasmaspheric hiss: 1. Dependence on chorus wave emission [PDF]
Journal of Geophysical Research: Space Physics, 2012 There is increasing evidence that plasmaspheric hiss is formed by the evolution of a portion of chorus waves that are excited in the plasmatrough and propagate into the plasmasphere. Comparison between the statistical spatial distributions of these two emissions in the morning sector during active times from THEMIS over ∼3 years shows that the two ...
