Description

technical field [0001] The invention belongs to the field of weather modification, and relates to a method for calculating the diffusion range of a catalyst, in particular to a method for evaluating the effective catalytic range of a catalyst based on an aircraft operation mode. Background technique [0002] Catalysts are the primary spread material for weather modification operations. By sowing catalysts in some key links or cloud system parts in the natural process of clouds and precipitation, the microphysical process or dynamic characteristics of clouds can be changed, so that clouds and precipitation can develop in the direction expected by people, and huge social and social benefits can be obtained at a small cost. Economic, ecological, environmental and other benefits can directly serve disaster prevention and mitigation and alleviate water shortage contradictions. On the other hand, the weather modification effect test after cloud seeding operation is a special conc...
