Madeira island is a well‐known source of atmospheric and oceanic eddy activity, with relevant downstream impact in both media. Previous studies focused on the dynamics of the island wake environment, suggesting the relevance of different atmosphere–ocean interactions in its maintenance. Here, results from one summer (two months) of fully coupled atmosphere–ocean high‐resolution simulations are used to explore such interactions and to further understand the dynamics of Madeira's wake. Those results, validated against available in situ and remote‐sensing data, indicate that the atmospheric and ocean circulations near Madeira are dominated by the variability of two quasi‐permanent features, its tip‐jets, and more so by the variability of its eastern jet. While both jets are of comparable magnitude and present similar intraseasonal variability at the multi‐week time‐scale, they are associated with qualitatively different forcing. The jets dominate the atmosphere forcing over the upper ocean, leading to enhanced mixing and deeper mixed‐layer depth. Oceanic eddies are more frequent in the east jet region, as shedding anticyclones, confirming observational evidence. A comparison with a similar one‐way coupled atmospheric simulation indicates that atmosphere–ocean feedbacks are relevant to the coastal surface temperature.

马德拉喷头的动力学和海洋响应

马德拉岛是大气和海洋涡旋活动的著名来源，在两种媒介中都具有相关的下游影响。先前的研究集中在岛屿尾迹环境的动力学上，表明了不同的大气-海洋相互作用对其维护的相关性。在这里，使用一个夏天（两个月）完全耦合的大气-海洋高分辨率模拟得到的结果来探索这种相互作用并进一步了解马德拉群岛的尾流动力学。那些结果，根据现场可用进行了验证和遥感数据表明，马德拉岛附近的大气和海洋环流主要由两个准永久性特征（即顶喷）的变异性决定，而更主要的是由其东部喷头的变异性决定。虽然两种喷气机的大小都相当，并且在几周的时间尺度上呈现相似的季节内变化，但它们在质力上却存在差异。喷流支配着强迫进入上层海洋的大气，从而导致混合增强，混合层深度更深。在东急流区域，海洋涡流更为频繁，因为旋流分离，这证实了观测证据。与类似的单向耦合大气模拟的比较表明，大气-海洋反馈与沿海地表温度有关。
