研究台风风场的规律并进行真实感仿真对于灾害预防、评估及宣传等有着十分重要的意义.首先从台风的物理特性出发,建立了不对称的3维台风风场,可以得到不同情况下台风的强度和风速变化;然后根据卫星云图的干区移动来预测台风移动路径;进一步模拟台风风场与物体的交互作用,实现了台风风场的3D可视化仿真预测和动态台风场景的实时绘制,得到了逼真的仿真效果.

It is of much significance for disaster rescuing, evaluating, and propaganda, to do the research of the typhoon wind-field rules and realistic simulation. Based on physical characteristics of typhoon, this paper first builds the 3D asymmetry typhoon wind-field model, and through simplifying and dispersing, calculates different wind speeds in different conditions. Then combined with the real-time satellite images, the profile, intensity, track and moving velocity of typhoon are simulated. Further, considering the movement under different conditions for different rigid and flexible objects, and using these realistic rendering technologies, We simulated the dynamic typhoon scene successfully based on its characteristics finally. The simulation results are very realistic.
