| 摘 要： | 简略介绍了描述云中水凝物粒子群尺度谱演变的方法：谱函数方法和分档方法，并给出了分档模式实例。讨论了谱参数本身以及在应用中应注意的问题。分析了两类方法的对比研究的结果指出，一些重要的云降水物理过程，如粒子类型间的转化，涉及粒子运动状态和人工播撒的效应等过程，应当用分档方法来处理。

| Abstract: | The schemes in numerical model of study the evolution of size distribution spectrum of hydrometeoro particles can be divide into two types:parameterization method and category method,and an example of category SGBH model is given.Some questions of itself or in application of parameterization methods are discussed.The results of discussion indicate that the category method have to use in the treatments for the production of future generation particles by autoconversion, artificial seeding effects and the processes concerned obviously the move regime of particles. |
