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.
