Fluxes of the trapped relativistic electrons can vary by several orders of magnitude over time scales of less than a day. Resonant interactions between plasma waves and the trapped electrons have been proposed to explain the variations, including interactions with plasma waves near the electron cyclotron frequency, and interactions with magnetohydrodynamic waves near the electron (longitudinal) drift frequency. I will describe computational methods that have been developed to provide increasingly realistic simulations of these interactions, and present recent measurements from the NASA Van Allen Probes spacecraft that enable detailed investigations of radiation belt physics.
