赤道西印度洋带状珊瑚的氧同位素组成提供了厄尔尼诺-南方涛动（ENSO）现象和亚洲季风之间关系的150年历史。珊瑚时间序列中的年际周期与太平洋珊瑚和仪器气候记录相关，表明尽管厄尔尼诺/南方涛动的频率和幅度不断变化，但海洋盆地之间存在一致的联系。然而，季风系统特有的年代际变化也主导着珊瑚记录，这意味着热带和中纬度气候变化之间的重要相互作用。这种相互作用的一个突出表现是准两年周期的强振幅调制。
The oxygen isotopic composition of a banded coral from the western equatorial Indian Ocean provides a 150-year-long history of the relation between the El Nino-Southern Oscillation (ENSO) phenomenon and the Asian monsoon. Interannual cycles in the coral time series were found to correlate with Pacific coral and instrumental climate records, suggesting a consistent linkage across ocean basins, despite the changing frequency and amplitude of the ENSO. However, decadal variability that is characteristic of the monsoon system also dominates the coral record, which implies important interactions between tropical and midlatitude climate variability. One prominent manifestation of this interaction is the strong amplitude modulation of the quasi-biennial cycle.
