摘　　要：低空大气环境是直升机飞行仿真的重要组成部分。基于综合自然环境(SNE,Synthetic NatureEnvironment)建模与仿真原理,开发了低空大气环境计算模型,探讨了分布式交互仿真中大气环境的建模方法,并基于VIS5D(Visualization of Large 5-D Gridded Data)实现了低空大气环境的可视化。The low level atmosphere is one of the indispensable components in the helicopter＇s aero simulation. Based on the synthetic natural environment modeling and simulation principle, the atmospheric computation model was developed. The method of modeling the atmosphere in distributed interactive simulation was also discussed. The low level atmosphere was visualized by VISSD.
