摘要
在山东飞机人工增雨效益估算系统中 ,根据冷云催化剂扩散模式 ,以作业区内碘化银粒子扩散的浓度为依据 ,确定飞机人工增雨的影响区 ;以天气系统历史降雨量的分布等条件确定对比区 ;采用单次天气系统分层历史回归或区域对比的统计方法确定增雨量。该系统在较客观地选择对比区和影响区的问题上有较大的改进。程序操作简单 ,实现了业务化。
In this system the target area is determined according to the diffusion model of cold cloud catalyst and the diffusion concentration of silver iodide particles in the operation area, the contrast area is determined based on conditions such as the rainfall distributions of historical weather systems, and the precipitation enhancement is calculated by using the layered regression for a single weather system or the region contrast method. The system shows improvements in the objective selection of the contrast area and the target area. It is simple to operate and has come into daily routine use.
