摘　　要：为获得飞机人工增雨作业后在一定区域和一定时段内的充分催化效果,文章基于扩散计算解析理论,考虑作业层风速及作业飞行速度等因素影响,给出不同作业范围内顺风和逆风作业时催化有效或者显著时的具体作业航线设计方法。计算并列出了不同作业层风速及航速下,耕作作业单条航线与垂直高空风之间设计夹角参考值及两条催化航线间距的参考值,为飞机人工增雨作业指挥提供依据。In order to achieve sufficient catalytic effects in a certain area and timeframe after artificial rain enhancement operations,this paper proposes a specific design method for operation routes when the catalytic effect is effective or significant during downwind and upwind operation in different operating ranges,considering the influence of wind speed at the operational layer and the flight speed during operations.The method is based on diffusion calculation and analysis theory.The angle between a single operation route and the vertical high-altitude wind and the distance between two catalytic routes under different wind speeds at the operational layer and flight speeds are calculated,which can provide basis for scientific and precise operations of aircraft precipitation enhancement.
