Abstract.  Based on the phase space Lagrangian Lie-transform perturbation method and the field theory, a reduced kinetic model with large E×B flow beyond the standard ordering (vE×B/vthO(ρ/L)) is constructed by modifying the guiding-centre phase space transformation. Some aspects of the model are revealed and effects of the flow are discussed in course of comparison with the standard model. The push-forward representation of general particle fluid moment is presented in the subsonic flow case. In sonic flow case, corrections to the reduced quasi-neutrality condition due to the E×B flow are found by variational derivation of the push-forward representation of particle density.
