| 摘 要： | 通过建立层状云雨滴的分档模式，对中国北方常见的三类典型层状云降水形成的微物理过程以及冰粒子在降水形成中的作用进行了数值模拟。结果表明，对于由冰粒子驱动的降水过程，由于高空冰粒子的增长降落表现出一种准周期变化过程，导致与之相关的云水含量，雨水含量也出现准周期性的演变，这种演变在雨滴分档模式中能够较好地反映到降水过程中。

| Abstract: | Based on observations in northern China, the microphysical process of precipitation formation and the role of ice crystal playing in those processes for three kinds of typical stratiform clouds are analyzed using rain category model. Results show that for ice-driven precipitation processes, the precipitation processes and other variables have quasi-periodic variation in intensity due to the periodic seeding process of ice particles, which can be well described and indicated in rain category model. |
