| 摘 要： | 针对人工影响天气飞机播云作业效果评估需求,提出一种基于拉格朗日粒子扩散模式FLEXPART-WRF的催化剂催化范围模拟评估方法.以典型催化剂碘化银为例,开发催化剂物理化学特性参数清单模块,结合飞机播云特点和模式源项特点,将飞机不规则线性播撒方式离散化为连续移动点源播撒方式,实现模式对飞机播云的模拟能力.通过对一次飞机播云作业的模拟试验,证实了模拟评估方法的可行性和有效性.

| Abstract: | A simulation evaluation method of catalyzed area based on Lagrangian particle diffusion model is proposed to evaluate the effect of aircraft cloud seeding operation in weather modification. Taking the typical catalyst silver iodide as an example, the physical and chemical characteristic parameter list module is developed. According to the characteristics of aircraft cloud seeding and the model source term, the irregular linear seeding mode of aircraft is discretized into the continuous moving point source seeding mode. As a result, the model has the ability to simulate silver iodide diffusion. The feasibility and validity of the method are verified by the simulation experiment of an aircraft cloud seeding case. |
