项目摘要
The Atlantic meridional overturning circulation (AMOC) is a large-scale redistribution of heat and freshwater that impacts weather and climate. This project will use numerical models of the ocean circulation to examine the long record of observations from moorings deployed in the North Atlantic. The goals include diagnosing the mass, heat, and freshwater fluxes of the AMOC and assessing the relationships between observations of ocean properties at the moorings and ocean or atmospheric properties at other locations. The project will also determine the optimal mooring array design for observing the AMOC. The project includes outreach to middle and high school students entered around the North Atlantic Ocean and its unique role in climate.This project will use a suite of ocean models, including the ECCO variational data assimilation model system, to examine the long time-series of observations from North Atlantic mooring arrays (including OSNAP and RAPID-MOCHA). The goals include: assimilation of Atlantic array data into global and regional ocean state estimates to assess the value they add to independent elements of the Global Ocean Observing System; diagnosing relationship of observed mass, heat and freshwater transport variability at the arrays to causal atmospheric forcing; identification of the potential for the array data to serve as proxies for remote, unobserved variables or indices of key oceanic and climatic relevance; and determining the optimal redesign of the OSNAP array for observing AMOC. The proposed research will complement ongoing major investments by NSF in observing the ocean role in climate through the AMOC and promises to ensure that future investments are as effective as possible.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
大西洋子午翻转循环(AMOC)是对天气和气候影响的热量和淡水的大规模重新分布。 该项目将使用海洋循环的数值模型来检查北大西洋部署的系泊设备的长期记录。这些目标包括诊断AMOC的质量,热量和淡水通量,并评估在系泊设备上的海洋特性与其他位置的海洋或大气特性之间的关系。该项目还将确定用于观察AMOC的最佳系泊阵列设计。该项目包括向北大西洋周围进入的中学和高中生的宣传及其在气候中的独特作用。该项目将使用一套海洋模型,包括ECCO变异数据同化模型系统,以检查北大西洋备忘录阵列(包括OSNAP和Rapid-Mocha)的长时间观测序列。目标包括:将大西洋阵列数据吸收到全球和区域海洋国家估算中,以评估它们添加到全球海洋观测系统独立元素中的价值;在阵列中观察到的质量,热量和淡水传输变异性与因果大气强迫的诊断关系;识别阵列数据作为远程,未观察到的变量的代理或关键海洋和气候相关性指标的潜力;并确定OSNAP阵列的最佳重新设计以观察AMOC。拟议的研究将补充NSF通过AMOC观察气候中海洋角色的持续重大投资,并承诺要确保未来的投资尽可能有效。该奖项反映了NSF的法定任务,并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来获得支持的。
