来自北方红海的年度带状珊瑚礁提供了地中海盆地东南边缘过去气候变化的高分辨率档案。来自这些大规模殖民地的碳酸盐骨骼的亚季节分解氧同位素记录有力地记录了季节性和年际到年代际的气候变化。这些气候的代用记录，仪器数据和模式模拟分析的支持下，揭示了北极涛动/北大西洋涛动（AO/NAO）在控制地中海东部/中东气候的季节性，年际到十年和轨道时间尺度，最显着的作用在冬季。珊瑚记录中5- 6年的年际变化表明，北方半球类似AO/NAO的大气变化及其对上个世纪、全新世晚期和末次间冰期地中海东部/中东气候的影响。记录红海北方温度和表面蒸发的珊瑚氧同位素记录通过AO/NAO控制的大气环流变化与整个地中海和中东地区的温度和降水变化相联系。而整个东地中海/中东地区的AO/NAO的高指数状态期间经历寒冷的冬天，由此产生的水文平衡的变化有一个更复杂的空间格局。红海北方更加干旱的情况伴随着地中海东北部更加干燥的冬季，但地中海东南部边缘沿着的冬季更加潮湿。这一观察可能会增加困难的代理为基础的重建地中海东部降水从黎凡特，这是位于正和负的降水异常之间的过渡区。与AO/NAO相比，ENSO对东地中海/中东地区气候的遥相关受北太平洋-北大西洋高纬大气环流的调制，其遥相关强度较弱且不稳定。
Annually banded reef corals from the northern Red Sea provide a high-resolution archive of past climate variations at the southeastern rim of the Mediterranean basin. Subseasonally resolved oxygen isotope records derived from the carbonate skeletons of these massive colonies robustly document seasonality and interannual to decadal climate variability. These proxy records of climate, supported by analyses of instrumental data and model simulations, reveal the prominent role of the Arctic Oscillation/North Atlantic Oscillation (AO/NAO) in controlling eastern Mediterranean/Middle East climate on seasonal, interannual to decadal and orbital timescales, most pronounced during winter. Variability at interannual periods of 5–6yr evident in the coral records is indicative of AO/NAO-like atmospheric variability over the Northern Hemisphere and its influence on eastern Mediterranean/Middle East climate during the last centuries, the late Holocene and the last interglacial period. The coral oxygen isotope records, which are recording temperature and surface evaporation in the northern Red Sea, are linked via AO/NAO-controlled atmospheric circulation changes to variations in temperature and precipitation throughout the Mediterranean and Middle East region. Whereas the entire eastern Mediterranean/Middle East region experiences colder winters during the high-index state of the AO/NAO, the resulting changes in hydrologic balance have a more complex spatial pattern. More arid conditions in the northern Red Sea are accompanied by drier winters in the northeastern Mediterranean but by wetter winters along the southeastern rim of the Mediterranean Sea. This observation may raise difficulties for proxy-based reconstructions of eastern Mediterranean precipitation from the Levant, which is located in the transition zone between positive and negative precipitation anomalies. Compared to the AO/NAO, the atmospheric teleconnections of the El Niño-Southern Oscillation (ENSO) on eastern Mediterranean/Middle East climate, which are modulated by higher-latitude atmospheric circulation over the North Pacific-North Atlantic region, are weaker and non-stationary.
