The Andaman coral reef region experienced mass bleaching events during 1998 and 2010. The purpose of this study is to investigate the role of the El Niño in the coral reef bleaching events of the Andaman region. Both Niño 3.4 and 3 indices were examined to find out the relationship between the mass bleaching events and El Niño, and correlated with sea surface temperature (SST) anomalies in the Andaman Sea. The result shows that abnormal warming and mass bleaching events in the Andaman Sea were seen only during strong El Niño years of 1997-1998 and 2009-2010. The Andaman Sea SST was more elevated and associated with El Niño Modoki (central Pacific El Niño) than conventional El Niño (eastern Pacific El Niño) occurrences. It is suggested that the development of hot spot patterns around the Andaman Islands during May 1998 and April-May 2010 may be attributed to zonal shifts in the Walker circulation driven by El Niño during the corresponding period.
安达曼珊瑚礁地区在1998年和2010年经历了大规模白化事件。本研究的目的是调查厄尔尼诺现象在安达曼地区珊瑚礁白化事件中的作用。研究了尼诺3.4指数和尼诺3指数，以找出大规模白化事件与厄尔尼诺现象之间的关系，并将其与安达曼海的海表面温度（SST）异常进行关联。结果表明，安达曼海的异常变暖及大规模白化事件仅在1997 - 1998年和2009 - 2010年的强厄尔尼诺年份出现。与传统厄尔尼诺现象（东太平洋厄尔尼诺）相比，安达曼海的海表面温度在厄尔尼诺模态（中太平洋厄尔尼诺）期间升高得更多。研究表明，1998年5月和2010年4 - 5月安达曼群岛周围热点模式的形成可能归因于同期由厄尔尼诺现象驱动的沃克环流的纬向移动。
