Circulation and Variability in the Mid-Latitude N. Atlantic Ocean

0219644 JoyceFunding是为主要研究者对北大西洋长期变化的研究提供为期两年的延续，作为基于成就的更新。 这一研究项目的基础是世界海洋环流实验的成功实地方案，以及对大多数巡航数据和与该区域十年变化有关的其他数据的分析。将调查的具体专题是：（1）继续利用52 W水文剖面的现场数据和反向方法研究纬向环流;（2）了解副热带环流的亚年度能量的性质和来源，在百慕大长时间序列和高度计中，亚热带环流似乎支配着年际能量;（3）探讨了科德角以南陆坡水域海温异常持续性强的原因;并将替代数据的使用扩展到冬季气候变率的研究，可追溯到世纪，北大西洋涛动（NAO）的敏感性。

0219644 JoyceFunding is provided for a two year continuation of the principal investigator's studies on the long-term variability of the North Atlantic as an Accomplishment Based Renewal. This research project builds on the successful field program of the World Ocean Circulation Experiment (WOCE), and the analysis of most of the cruise data and other data relating to decadal variability in the region. The specific topics that will be investigated are: (1) continued studies of zonal circulation using in-situ data and inverse methods for the 52W hydrographic section; (2) understanding of the nature and source of sub-annual energy in the subtropical gyre, which seems to dominate inter-annual energy both in the long Bermuda time series and for the altimeter; (3) investigation of the reason for strong persistence of SST anomalies in the region of the Slope Water south of Cape Cod; and extending the use of proxy data for the study of wintertime climate variability extending back into the 19th century to understand long-term cycles in sensitivity to the North Atlantic Oscillation (NAO).
