Long-term simulations of energetic electron fluxes in many space plasmasystems require accounting for two groups of processes with well separatedtime-scales: microphysics of electron resonant scattering by electromagneticwaves and electron adiabatic heating/transport by mesoscale plasma flows.Examples of such systems are Earth's radiation belts and Earth's bow shock,where ion-scale plasma injections and cross-shock electric fields determine thegeneral electron energization, whereas electron scattering by waves relaxanisotropy of electron distributions and produces small populations ofhigh-energy electrons. The applicability of stochastic differential equationsis a promising approach for including effects of resonant wave-particleinteraction into codes of electron tracing in global models. This study isdevoted to test of such equations for systems with nondiffusive wave-particleinteractions, i.e. systems with nonlinear effects of phase trapping andbunching. We consider electron resonances with intense electrostaticwhistler-mode waves often observed in the Earth's radiation belts. Wedemonstrate that nonlinear resonant effects can be described by stochasticdifferential equations with the non-Gaussian probability distribution of randomvariations of electron energies.
