    From the nonlinear effects of ultraviolet beam in air, the beam propagation equation which includes several nonlinear effects, such as the three-photon ionization of oxygen, is obtained. From this nonlinear Schrdinger equation, the generation of localized optical vortex soliton (LOVS) for ultraviolet light in air is investigated. The LOVS dynamics is homologous to the movement of particles in a potential well. The initial conditions for the generation of LOVS in air are analyzed. Numerical simulations show the LOVS solutions in polar coordinates, and in the solutions of equation many rings appear with the increase of initial amplitude. Finally, the light-intensity distribution′s variation as propagation constant is confirmed numerically. Numerical simulations also show the relation of beam size, power and initial amplitude. The stability of solution is checked by the stability criterion of Skarka.
