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

利用高分辨率的大气、海洋和海气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，陡峭的海面温度梯度有助于维持大气天气扰动活动和气候平均大气环流，后者由前者的集体反馈维持。此外，一个积极的反馈之间的大气响应海洋锋的轴向变化和大气强迫，诱导海洋锋的变化摆在首位，反馈，可能有助于加强在北太平洋的海气耦合的变化。

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.
