摘要: 针对动态云在快速模拟下的真实感缺乏问题,提出一种改进的动态云的模拟方法。该方法在Nagel方法模拟云的基础上,考虑到大气压对自然云形状的影响,通过建立上下气流动力学方程,实现具有真实感的动态云的模拟。结果证明,与常规方法相比,该方法具有运算速度快、模拟效果逼真等优点。

Abstract: Aiming at the problem of the lackness of reality in the quick imitation of dynamic cloud, this paper proposes an improved method of dynamic cloud simulation. Based on Nagel simulation, considering the influence of atmospheric pressure to cloud in the natural state, through establishing the dynamic equation of fluctuation airflow, the method implements the simulation of realistic dynamic cloud. Result shows that it features in fast calculation speed and high fidelity of simulation compared with conventional methods.

Key words: cellular automaton, simulation of cloud, wind function, atmospheric pressure
