本文利用天气涡旋和低频流（SELF）相互作用的动力学模型，证明了SELF反馈对冬季和夏季AO/NAO的形成具有重要意义。虽然夏季背景风暴活动明显弱于冬季，但夏季与AO/NAO模态相关的SELF正反馈与冬季一样强。发现AO/NAO空间型的季节变化与SELF相互作用的线性动力系统模拟的主要奇异模态相似，其空间型的季节变化是气候基本状态和天气涡旋活动的季节变化的结果。
In this paper, by using a dynamic model with synoptic eddy and low‐frequency flow (SELF) interaction, we show that the SELF feedback is of significant importance for the formation of the AO/NAO in both winter and summer. Although background storm activity is significantly weaker in summer than that in winter, the positive SELF feedback associated with the AO/NAO mode in summer can be as strong as that in winter. The seasonal variations of the AO/NAO patterns are found to resemble those of the leading singular modes simulated by a linear dynamic system with the SELF interaction in different seasons, and the seasonal shifts in spatial patterns of the AO/NAO are the result of the seasonal changes in climatological basic state and synoptic eddy activity.
