热浪是大气和海洋系统中的重要气候，可能对生态系统产生毁灭性和长期影响，并随后产生社会经济后果。最近著名的海洋热浪吸引了相当大的科学和公共利益。尽管如此，对全球这些海洋温度如何在全球范围内如何变化的全面评估。使用一系列海洋温度数据，包括每日卫星观测的全球记录，每天的原位测量以及每月在基于原位的数据集中进行网格，我们确定了过去一个世纪海洋热浪的显着增加。我们发现，从1925年到2016年，全球平均海洋热浪频率和持续时间分别增加了34％和17％，导致全球年度海洋热浪天数量增加了54％。重要的是，这些趋势在很大程度上可以通过平均海洋温度的升高来解释，这表明我们可以期望在持续的全球变暖下，海洋热浪天数进一步增加。
海洋热浪是极端的气候，对海洋生态系统，渔业和水产养殖具有毁灭性和长期影响。在这里，作者使用一系列海洋温度观测来确定过去一个世纪海洋热浪的显着增加。
Heatwaves are important climatic extremes in atmospheric and oceanic systems that can have devastating and long-term impacts on ecosystems, with subsequent socioeconomic consequences. Recent prominent marine heatwaves have attracted considerable scientific and public interest. Despite this, a comprehensive assessment of how these ocean temperature extremes have been changing globally is missing. Using a range of ocean temperature data including global records of daily satellite observations, daily in situ measurements and gridded monthly in situ-based data sets, we identify significant increases in marine heatwaves over the past century. We find that from 1925 to 2016, global average marine heatwave frequency and duration increased by 34% and 17%, respectively, resulting in a 54% increase in annual marine heatwave days globally. Importantly, these trends can largely be explained by increases in mean ocean temperatures, suggesting that we can expect further increases in marine heatwave days under continued global warming. Marine heatwaves are climatic extremes with devastating and long-term impacts on marine ecosystems, fisheries and aquaculture. Here the authors use a range of ocean temperature observations to identify significant increases in marine heatwaves over the past century.
