摘要
This paper provides a brief review of the role that chorus waves play in controlling the dynamics of the Earth's outer radiation belt. Three major topics are discussed: (i) the morphology, characteristics, and properties of chorus waves themselves, with special emphasis on more recent results, (ii) the role that chorus waves play in the loss of radiation belt particles, showing initial results from modeling of relativistic electron microbursts, and estimated lifetimes based on microburst occurrence rates during the main phase of storms, and (iii) the role that chorus waves play in the acceleration of electrons to relativistic energies in the recovery phase of storms, based on a new quasilinear diffusion based calculation.
