摘　　要：利用冷云人工增雨冰水转化理论,较详细地分析了一个黄淮气旋的垂直结构。讨论了该气旋不同发展阶段、不同部位有利于冰晶通过水汽凝结或凝华增长的条件,给出了作业前根据宏观物理量确定气旋中播云区的方法。分析表明,在气旋初生期,气旋各部位的冷层都有较好的水汽条件;在气旋发展旺盛时,冷锋前和暖锋前的冷层水汽条件较好;在气旋锢囚后,只有暖锋前的冷层和气旋中心水汽较多。而暖锋前的冷层中总是液态水最多的部位。It is analyzed the perpendicular structure of a Huanghuai cyclone. Using the ice-water con version theory in seeding of cold cloud, the conditions of ice crystal growing up are discussed in different times and positions of cyclone by condensation or sublimation. The methods of confirmation seeding area in cyclone are made before operation. When the temperature is below 0℃, in nascent period of cyclone, it is showed there are fine water vapor conditions anywhere in cyclone. In developing period of cyclone, there are fine water vapor conditions at the fore of cold and warm fronts. After cyclone occlude, there are only fine water vapor conditions at fore warm front and cyclone center. But there are always much liquid water in cold cloud at the fore of warm front.
