Abstract : A brief review of the gyroresonant wave-induced precipitation of energetic radiation belt particles is presented using the particular case of interactions involving lightning-generated whistler waves as an example. The interaction physics is first discussed in the context of results from a recently developed theoretical model of the whistler-particle scattering process occurring in the magnetosphere. This is followed by a discussion of the 'Trimpi' effect, a particularly sensitive ground-based technique that has recently been increasingly used for detecting ionospheric perturbations produced by whistler-induced energetic particle precipitation from the magnetosphere on L-shells of 2-5.
