摘要通过对最近文献的调查，对海冰的气候作用进行了评估。理论或基于模型的结果与现有的冰-大气相互作用的证据进行了比较，范围从地方和区域到半球和全球。证据表明，海冰波动在当地具有重要的气象意义，主要是与气温有关。在区域和半球尺度上，根据观测证据和模型实验，大气和海冰波动是相关的。虽然因果联系还没有得到定量评估，但有证据表明，更强的信号出现在冰对大气的反应中。在更长的时间尺度上，模式实验和定性论证表明，海冰可能在气候变化中发挥主要作用。然而，大规模耦合模式模拟的结果存在不足，在对海冰进行更现实的处理之前，必须谨慎对待。
Abstract The climatic role of sea ice is assessed in a survey of the recent literature. Theoretical or model‐based results are compared with existing evidence of ice‐atmosphere interactions over scales ranging from the local and regional to the hemispheric and global. The evidence shows that sea‐ice fluctuations are meteorologically important locally, primarily through associations with air temperature. On the regional and hemispheric scales, atmospheric and sea‐ice fluctuations are correlated according to both observational evidence and model experiments. While the causal links have not been evaluated quantitatively, there is evidence that the stronger signal occurs in the response of the ice to the atmosphere. On the longer time‐scales, model experiments and qualitative arguments suggest that sea ice may play a major role in the climatic change. However, the results of large‐scale coupled model simulations contain deficiencies and must be viewed with caution pending more realistic treatments of sea‐ice ...
