Interaction between Ocean fronts and the Atmosphere in the Kuroshio Extension Region.

利用高分辨率大气、海洋和大气-海洋耦合模式，研究了黑潮延伸区海洋锋与大气的相互作用。结果表明，海面温度的急剧梯度有助于维持大气天气扰动活动和气候平均大气环流，后者是由前者的集体反馈维持的。此外，正反馈在大气对海洋锋轴向变化的响应和首先引起海洋锋变的大气强迫之间起作用，这种反馈可能有助于增强北太平洋的大气-海洋耦合变率。

Interaction between ocean fronts and the atmosphere in the Kuroshio Extension region is investigated using high-resolution atmosphere, ocean, and atmosphere-ocean coupled models. It is demonstrated that sharp sea surface temperature gradients help to maintain atmospheric synoptic disturbance activity and climatological mean atmospheric circulation with the latter sustained by collective feedback from the former. Furthermore, a positive feedback is suggested to be operative between the atmospheric response to axial variations of ocean fronts and the atmospheric forcing that induces the oceanic frontal variation in the first place, a feedback that likely helps enhance the atmosphere-ocean coupled variability in the North Pacific.
