The tripolar structure SST anomalies over the North Atlantic, which also appears at the interannual scale with a spectral peak at 3—4 years, are mainly resulted from the barotropic driving of the NAO like atmospheric forcing, and thermal process plays a dominantrole in this process. When the NAO is strong, the westerly weakens over the midlat itudes; both the sensible and the latent heat flux release from the ocean tend to decrease, which warms the ocean and leads to positive SST anomalies. Over the sub polar region including the Labrador Sea, a stronger NAO is associated with a deeper Icelandic Low; the high latitudes originated colder air then blows over the ocean surface, the air-sea temperature difference become larger, and the se n sible heat flux loss from the ocean increases, which subsequently leads to colder SST anomalies.

分析表明，模式中三核型SST异常的产生，主要来自大气的强迫，NAO增强，中纬度大洋上的西风减弱，海洋感热和潜热通量损失减少，中纬度大洋得到的净热通量增加，导致SST出现正距平；在包括Labrador 海在内的副极地大洋，NAO增强、冰岛低压加深，气旋性环流增强，来自高纬度的冷空气吹过洋面，海气温差加大，大洋的感热通量损失增加，SST降低。
