The paper presents the results of numerical simulation of the extended atmospheric pressure discharge in configuration of the tip-to-plane diode. The simulation is based on a hydrodynamic model of a discharge plasma in a pure O 2 medium at low average electric field strengths ~ 10 kV·cm −1 . It was investigated how initial conditions, such as the presence of a weakly ionized plasma channel or a given temperature profile on the discharge axis, influence on the formation of a discharge structure at the initiation stage.
