在1997年至1998年厄尔尼诺事件期间，台湾海峡冬季平均海表温度比冬季气候平均值高出∼1.4℃。温带的暖水(≥2℃以上)与冷水(≥2℃以下)的面积比增加了25%，而富营养化水体(叶绿素a和Gt；1 mg m−3)的面积减少了一半。野外观测还表明，TWS的混合层在今冬变得更加贫瘠。这些观测结果与浙闽沿岸冷、富营养化平流减弱相一致，同时，随着东北季风的减弱，温暖、少营养的南中国暖流/黑潮支流对TWS的扩张入侵。因此，厄尔尼诺事件可能对TWS产生重大的生态影响。
During the 1997–1998 El Niño event, the average sea surface temperature (SST) in the Taiwan Strait (TWS) in the winter was ∼1.4°C higher than that of the winter climatological mean. The areal ratio of the warm water (≥2°C above the regional mean) to the cold water (≥2°C below the regional mean) in the TWS increased by 25% while the area of the eutrophic water (chlorophyll a >1 mg m−3) was halved. Field observations also indicate that the mixed layer in the TWS became more nutrient‐poor during this winter. These observations are consistent with a diminished advection of the cold and eutrophic Zhe‐Min Coastal Water, and, concomitantly, an expansive intrusion of the warm and oligotrophic South China Sea Warm Current/Kuroshio Branch Water to the TWS as the northeast monsoon was weakened. Thus, El Niño events potentially can have significant ecological impacts on the TWS.
