2014.06.10【英译中】回到未来测定海平面上升是否在加快(1)


The study found that the most important approach to the earliest possible detection of a significant sea level acceleration lies in improved understanding (and subsequent removal) of interannual (occurring between years, or from one year to the next) to multidecadal (involving multiple decades) variability in sea level records.

研究表明,对显著海平面上升加速的早期可能监测,最重要的是提高对年际(年与年之间的比较)及年代际(每10年一个年代,年代与年代之间的比较)海平面变化(及其趋势)的理解。


“The measured sea levels reflect a variety of processes operating at different time scales,” says co-author Dr Francisco Calafat, from the National Oceanography Centre. He adds, “One of the main difficulties in detecting sea level accelerations is the presence of decadal and multi-decadal variations. For example, processes associated with the North Atlantic Oscillation have a strong influence on the sea levels around the UK over multi-decadal periods. Such processes introduce a large amount of ‘noise’ into the record, masking any underlying acceleration in the rate of rise. Our study shows, that by adequately understanding these processes and removing their influence, we can detect accelerations much earlier.”
“海平面测量反映了对大范围海洋活动在不同时间尺度上的处理。”来自国家海洋中心的联合作者Francisco Calafat博士表示。他补充说:“对海平面上升加速度监测的主要困难之一是存在着年际和年代际变化。”比如,与北大西洋涛动有关的海洋活动对英国周边海平面年代际的变化有着极大的影响。这些活动在记录中产生了大量的‘噪声’数据,掩盖了海平面上升过程中潜在的加速情况。我们的研究显示,通过对这些活动的充分认识从而去除它们的影响,就能够更早地监测到加速情况。

Co-author Professor Eelco Rohling, from the Australian National University and formerly of the University of Southampton, adds: “By developing a novel method that realistically approximates future sea level rise, we have been able to add new insight to the debate and show that there is substantial evidence for a significant recent acceleration in the sea level rise on a global and regional level. However, due to the large ‘noise’ signals at some local coastal sites, it won’t be until later this decade or early next decade before the accelerations in sea level are detection at these individual tide gauge sites.”
前南安普顿大学教授、来自澳大利亚国立大学的联合作者Eelco Rohling教授,补充道:“通过开发出一种新的方法来实际预估未来海平面上升情况,我们成功地在这场讨论中注入了新的见解。这表明我们有确切的证据证明全球范围或是特定海域海平面近期显著的上升加速情况。但是,由于巨大‘噪声’信号在某些沿海地区的影响,大概需要到本年代末或到下年代初才能对这些特定验潮站的海平面上升加速情况进行监测。”
