| 摘 要： | 该文提出了新的层状云人工增雨机制，指出人工冰晶除通过贝吉隆过程使过冷云水转化为降水外，还使一部分冰面过饱和水汽转化为降水，凝华潜热的释放导致空气增温和局部升速加大，促进云降水的发展。与此相应提出了适合人工增雨的云层条件、监测识别方法以及最佳催化部位、药剂、剂量等。

| Abstract: | A new mechanism of precipitation enhancement in stratiform clouds is proposed.It is suggested that supersaturated water vapor with respect to ice would be converted into precipitation after ice seeding besides supercooled water.The release of sublimation latent heat leads to the increase of temperature and updraft in the seeded cloud regions.The cloud condition suitable for seeding,its monitoring method and optimum seeding location,agent and dosage were discussed according to the new mechanism. |
