着重分析和讨论全球大气，海洋－海冰耦合环流模式的两个长时间数值积分试验──１３０年控制试验和９５年敏感性试验（增强温室效应试验），尤其是控制试验中的气候漂移现象以及与此相关的敏感性试验中增援信号的提取问题。在控制试验中，大气二氧化碳浓度维持当前的气候值不变；而在敏感性试验中，大气二氧化碳浓度开始时以１％的速率等比增加，它在积分至７０年且其值已达初始值的二倍后便不再变化。分析结果表明，尽管这个耦合模式的长时期积分中存在着明显的气候漂移，但敏感性试验给出的全球增暖的基本特征在物理上是合理的；这个耦合模式产生气候漂移的主要源地是在高纬度海洋的冰水交界区，且初步的热收支估算揭示它可能与冰－水交界区的耦合方案有关。本文最后在对控制试验和敏感性试验的环流型式的时间演变进行相关分析的基础上给出了有关全球增暖幅度的３种估计，同时指出：尽管全球增暖的空间分布不可避免地要受到模式气候漂移的影响，但这种影响的大部分在计算气温年较差的变化时却可以被自动扣除。
Focusing on the analysis and discussion of two long-term numerical integration tests of the global atmospheric-ocean-sea-ice coupling circulation model, the 130-year control experiment and the 95-year sensitivity test (enhancing the greenhouse effect test), especially the climate drift in the control experiment As well as the sensitivity test associated with the extraction of reinforcement signals. In control experiments, the atmospheric carbon dioxide concentration remained unchanged for the current climate; in the sensitivity test, the atmospheric carbon dioxide concentration initially increased at an equal rate of 1%, and it reached an initial value of 70 years after integration Twice the change will not change. The results show that although the long-term integral of this coupled model has significant climate drift, the basic features of global warming given by sensitivity experiments are physically justified; this coupling mode is the main source of climate drift Is the ice-water junction in the high latitude oceans, and a preliminary estimate of the heat budget reveals that it may be related to the coupling scheme for the ice-water junction. At the end of this paper, we give three kinds of estimations about the global warming extent based on the correlation analysis of the circulation patterns of control and sensitivity experiments. At the same time, we point out that although the spatial distribution of global warming is inevitably affected Mode of climate drift, most of this impact can be automatically deducted when calculating the poor annual change in temperature.
