厄尔尼诺（ElNiño）偏南振荡是整个太平洋盆地的年度气候变异性的主要模式，对全球气候的影响有影响。太平洋边缘，暴露了许多人口稠密的地区，以增加沿海洪水和侵蚀危险。在空间上有限，仅限于最近的事件。整个美国西海岸的历史最大值，对应于整个地区的大型海滩侵蚀。特别是沿着蓄积的加利福尼亚海岸。
ElNiño和LaNiña的ENSO最终成员与整个太平洋地区的沿海危害相关。最近145年。
The El Niño-Southern Oscillation is the dominant mode of interannual climate variability across the Pacific Ocean basin, with influence on the global climate. The two end members of the cycle, El Niño and La Niña, force anomalous oceanographic conditions and coastal response along the Pacific margin, exposing many heavily populated regions to increased coastal flooding and erosion hazards. However, a quantitative record of coastal impacts is spatially limited and temporally restricted to only the most recent events. Here we report on the oceanographic forcing and coastal response of the 2015–2016 El Niño, one of the strongest of the last 145 years. We show that winter wave energy equalled or exceeded measured historical maxima across the US West Coast, corresponding to anomalously large beach erosion across the region. Shorelines in many areas retreated beyond previously measured landward extremes, particularly along the sediment-starved California coast. ENSO end members El Niño and La Niña are linked to elevated coastal hazards across the Pacific region. Here, the authors show that the wave conditions and coastal response for the 2015–16 El Niño indicate that it was one of the most significant events of the last 145 years.
