摘要
本文用一维辐射·对流模式系统地研究了现有含氯氟烃气体(CFCs)及其可能代用品的辐射强迫、比地面增温效应和全球增温潜能(GWP).结果发现:大多数提议的代用品的GWP值明显小于现有的CFCs.这主要归因于:(1)它们所产生的辐射强迫和比地面增温效应较小,一般只有CFCs的50％—60％;(2)其大气寿命比CFCs短得多.
The radiative forcing, Specific surface warming and global warming potential (GWP) due to the chrolofluorocarbons and their possible substitutes have been examed in detail by using an one-dimensienal radiative-convective model. The results show that the GWP values for most of the proposed substitutes to the CFCs are considerably smaller than those for the CFCs , Which are resulted from (1) the radiative forcing and specific surface warming due to the substitutes are less than the CFCs, in general, by 50%- 60% ; and (2) the atmospheric life time of the substitutes is much shorter .
