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.
大西洋纬向翻转环流(AMOC)是一种影响天气和气候的热量和淡水的大规模重新分配。 该项目将利用海洋环流的数值模型,审查部署在北大西洋的系泊观测的长期记录。这些目标包括诊断AMOC的质量、热量和淡水通量,并评估系泊处海洋特性观测与其他地点海洋或大气特性观测之间的关系。该项目还将确定观测AMOC的最佳系泊阵列设计。该项目包括对初高中学生的外联活动,这些学生在北大西洋及其在气候方面的独特作用周围进入,该项目将使用一套海洋模型,包括欧洲委员会合作组织变分数据同化模型系统,以审查来自北大西洋系泊阵列(包括OSNAP和RAPID-MOCHA)的长期观测序列。这些目标包括:将大西洋阵列数据同化为全球和区域海洋状况估计数,以评估它们对全球海洋观测系统的独立要素增加的价值;诊断阵列上观测到的质量、热量和淡水迁移变异性与大气作用力的因果关系;确定阵列数据作为远程、未观测变量或与海洋和气候有关的关键指数的替代物的潜力;并确定观测AMOC的OSNAP阵列的最佳重新设计。该研究计划将补充NSF在通过AMOC观察海洋在气候中的作用方面正在进行的重大投资,并承诺确保未来的投资尽可能有效。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
