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/vth∼O(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.
