To describe the processes of acceleration and transfer of charged particles in turbulent magnetospheric and solar plasmas, a two-dimensional model of a turbulent electromagnetic field with a controlled intermittency level is proposed. In the model, the electromagnetic field has two components: a turbulent electromagnetic field obtained in the form of a superposition of plane waves, and an electromagnetic field created by oscillating magnetoplasma structures—plasmoids. Within the framework of the model, the role of intermittency in the acceleration of charged particles is investigated. It is shown that, the larger the parameter characterizing the level of intermittency, the higher the energy values that the charged particles are able to reach. The use of the model for describing observations of high-energy particle fluxes in the Earth’s magnetosphere and in the solar wind is discussed.
