[1]大气层是否以及如何对热带外海面温度（SST）的变化做出反应正在激烈的辩论中，这种缺乏了解一直是研究非厄尔尼诺气候变率的主要障碍。使用新的卫星测量，我们发现明确的海洋到大气的反馈，在黄海和东海（YEC）的海底地形所触发的。在冬季强烈的地表冷却下，水的性质在100米深的地方混合得很好。因此，海洋深度对大陆架的SST有很大的影响，导致暖舌和深槽的显着搭配。在这些温暖的舌头上发现了强风和增加的云量;海洋-大气共同变化的一个这样的带蜿蜒穿过盆地，沿着一条深通道长达1000公里。除了这些气候影响，黑潮锋--暖流与更冷的陆架水相遇的地方--加强了风暴的增长。
[1] Whether and how the atmosphere reacts to changes in extratropical sea surface temperature (SST) is under intense debate and this lack of understanding has been a major obstacle in the study of non-El Nino climate variability. Using new satellite measurements, we detect clear ocean-to-atmospheric feedback in the Yellow and East China (YEC) Seas that is triggered by the submerged ocean bottom topography. Under intense surface cooling in winter, water properties are well mixed up to 100 m deep. Ocean depth thus has a strong influence on SST of the continental shelf, leading to a remarkable collocation of warm tongues and deep channels. High winds and increased cloudiness are found over these warm tongues; one such band of ocean-atmospheric co-variation meanders through the basin, following a deep channel for an amazing distance of 1000 km. In addition to these climatic effects, the Kuroshio Front-where the warm current meets the much colder shelf water-strengthens the growth of storms.
