Statistical Dependence of EMIC Wave Scattering on Wave and Plasma Parameters

A recent statistical study (Qin et al., 2018) has suggested that not all electromagnetic ion cyclotron (EMIC) waves can scatter relativistic electrons. However, knowledge of the factors that influence the EMIC wave scattering efficiency is still limited in observations.

Patel et al. observe that when an interplanetary shock launched from the Sun arrives at Earth, it compresses the dayside magnetic field and an impulse in electric and magnetic field propagates as a characteristic wave mode inside the magnetosphere toward the nightside.

Pitch angle scattering of energetic electrons by bursty bulk flows (BBFs)

Mary Hudson and others have studied field line curvature scattering by the magnetic field structure associated with Bursty Bulk Flows (BBFs), using simulated output fields from the Lyon‐Fedder‐Mobarry (LFM) global magnetohydrodynamic (MHD) code for specified solar wind input.

Modeling the radiation belt electron response to CME-driven storms: the first 9 months of the Van Allen Probes

Recent geomagnetic storms at solar maximum have produced dynamic variations in outer zone radiation belt electron flux measured in detail by the Van Allen Probe twin spacecraft,
