Abstract	With the purpose of study air-gap discharge phenomena at atmospheric pressure and deeply understanding behavior of barrier discharge in air-dielectric, the one dimensional and self-consistent fluid model of the gas discharge is established based on the electron and ion continuity and momentum transfer equations coupled to Poisson's equation, then the micro discharge progress of the air-dielectric and its influence of the surface charge accumulation on dielectric barriers under alternating voltage are analyzed and demonstrated in detail. The models of numerical simulations of dielectric barrier discharges of a plane-parallel electrode arrangement covered with solid dielectric and comprising an air gap are made up, and the results of simulation are obtained for the case when the applied field in the gas exceeds its breakdown threshold and discharge current pulses can be formed, i.e. charge transfer in the gas phase takes place in the form of an electron avalanche discharge, simultaneously, the facts were found that the temporal and spatial distributions of the electric field, electron density and the ion density obtained in the electron avalanche discharge at atmospheric pressure could improve the air-gap discharge performance, furthermore, the calculated discharge current patterns are found to agree structurally and also to correctly display the predicted avalanche.
