北大西洋大气环流年际变化的主要来源是北大西洋涛动（NAO），它与冬季海洋表面西风的强度有关。在上个世纪，北大西洋涛动表现出明显的多年和十年变化，这种波动伴随着北大西洋区域海洋和陆地生态系统的变化。本文提出了一个简单的模型，再现了NAO指数从1866年到2004年的主要趋势。该模式是基于气候共振器，迫使全球平均温度和南太平洋涛动（SO）。该模型的海洋部分显示出与北大西洋时间序列相似的变化。
The major source of interannual variability in the atmospheric circulation over the North Atlantic Ocean is the North Atlantic Oscillation (NAO), which is associated with the strength of the winter surface westerly winds over the Ocean. During the last century, the NAO has shown pronounced multi‐annual and multi‐decadal variations, fluctuations that have been accompanied by changes in the marine and terrestrial ecosystems of the North Atlantic region. This paper presents a simple model which reproduces the major trends in the NAO index from 1866 to 2004. The model is based on climatic resonators that are forced by the global mean temperature and the Southern Oscillation of the Pacific Ocean (SO). The ocean component of the model shows similar variations to time‐series from the North Atlantic.
