abstract = "The ultra-low frequency (ULF) waves can stochastically accelerate
radiation belt electrons. Radial diffusion is a well-established
mechanism that can enhance or reduce the electron population in
combination with other processes. Using data from the Van Allen
Probes, we investigated the response of the 2.10 MeV energy
electrons and ULF waves to two types of solar wind structures
interacting with Earth's magnetosphere, namely, interplanetary
coronal mass ejections (ICMEs) and High-Speed solar wind streams
(HSS). We use measured electron differential flux and ULF waves in
the Pc4-Pc5 frequency range from October 2012 to May 2019. We
examine 155 events with changes in the outer radiation belt
electron differential flux. Results considering all ICMEs and HSSs
during the Van Allen Probes era show that for both solar wind
structures, solar wind interplanetary magnetic field Bz, solar
wind proton density, and speed are related to the outer radiation
belt relativistic electrons' response. The persistent ULF power is
present during enhancement cases, while for reduction, the ULF
waves power is concentrated at the initial reduction on the outer
radiation belt electron flux.",
