摘要

Ultralow frequency (ULF) waves facilitate the transfer of energy from the solar wind into the magnetosphere, acting as a conduit through which energy and momentum are exchanged between different regions of near-Earth space. ULF waves can resonate with particles drifting and bouncing around the Earth, significantly altering their trajectories and energies. This review summarizes our understanding of ULF wave-particle interactions in the Earth’s magnetosphere, emphasizing the nonlinear characteristics of these interactions. The transition of drift resonance and drift-bounce resonance theories from linear approaches to nonlinear frameworks is also highlighted. By analytically and numerically quantifying the conditions under which these nonlinear interactions become pronounced, this review contributes to a deeper understanding of magnetospheric particle dynamics.
