Investigations of the structural arrangement of the atmospheric filamentary discharges were carried out. By observing the initial discharge events, we find that the surface charge plays a significant role of seeding electrons. The filamentary discharges show ordered and disordered patterns in parallel plates with different gap distances. A critical gap distance for an ordered pattern is found at about 700 μm. The transition of the order-disorder discharge pattern is also confirmed in a wedged-plates setup with a continuous change of gap distance. The bond-orientational function of the structure of the pattern is related to the mutual Coulomb interaction between discharges.
