Simulation of climate effects in fields of visual simulation system ,computer games and 3D animation has a wide range of applications ,it can greatly improve the realism of three-dimensional scene .Particle system is an effective way to simulate climate effects .In this paper ,we introduce the the principle of particle system ,mathematical model of particles as well as the creation of a custom particle system ,and then simulated the natural scene taking climate effects of rain and fog for example using technology of OSG and particle system .The experimental results show that custom particle system based on OSG can simulate more real climate effects ,the simulation effect is clear ,ideal for use in high-fidelity environ-ments .
