中文摘要:

      文中建立一个包含年平均云量、地表温度及边界层气温的零维能量平衡模式。研究表明:该模式在适当的参数值范围内,能模拟出接近实际的气候状态;根据与该模式相应的偏差方程,讨论了气候系统的非线性特征以及云对气候状态演化的作用。

英文摘要:

      In this paper, an energy budget model with zero-dimension, in which the annual mean global cloudness, surface temperature and atmospheric temperature in boundary layer are chosen as climatic variables, is proposed. The results show that this model can be used to simulate practical climate states in the suitable ranges of parameter values, and to discuss nonlinear properties of climate system basing on the deviation equations corresponding to this model and important role of cloud on the variation of climate states.
