| 摘 要： | 本文对全球平均、各纬带平均和几种特殊下垫面条件下大气顶和地表面的净辐射随云量变化的情况进行定量分析,并讨论了净辐射对云量变化的敏感性随各参数改变的情况。另外还定性地讨论了云在全球气候中的反馈作用以及这种反馈作用随各参数变化的特点。指出:一般条件下,净辐射对于云量变化是敏感的,只有当气候参数变化到临界值附近时,对气候的模拟可以不考虑云量的变化。从云量对气候的反馈来看,在气候参数发生变化时,气候系统的稳定性会发生本质的改变。

| Abstract: | Variations of the global mean and zonal mean net radiation in various surface conditions are analysed quantitatively with a changing cloud cover. The sensitivity of net radiation to the cloud cover and the variation of this sensitivity with the changes of other climatic variables are discussed. In addition, the feed-back of cloud cover in global climate system and its variation with other climatic variables are also dealt with qualitatively. It is found that net radiation is sensitive to cloud cover and only when climatic variab!es are near their critical values, can the variation of cloud cover be omitted in climatic medeling. Because of the feed-back of cloud cover, the stability of a climatic system may change substantially when climatic variable are changing. |
