Analysis of the WOCE ACM-1 Array: A Decadal Record of DWBC Variability East of the Bahamas

在这个项目中，调查人员将完成对大西洋西部边界系统1986年至1997年11年期间长期保持在北纬26.5度的海流计系泊设备的数据的处理、分析、解释和发布。总体重点将放在与北大西洋涛动(NAO)等大尺度强迫变化有关的年际时间尺度上的深再循环、海流结构和输送的性质和变异性上。调查人员将与大西洋海洋和气象实验室的NOAA科学家合作。具体目标是：1.确定巴哈马群岛以东的平均输送结构，包括西部边界流和延伸至近海600公里的深层再环流2.调查年际时间尺度上的变率及其与盆地范围风强迫和与NAO有关的高纬度对流活动变化的关系；3.利用海流计数据以及佛罗里达州海流和内部XBT(消耗性BathyThermograph)断面数据，改进对副热带大西洋经向海洋热量输送及其年和年际变率的估计；4.将海流计结果与高分辨率大气环流模式进行比较。

In this project, the Investigators will complete the processing, analysis, interpretation, and publication of data from a long term array of current meter moorings that was maintained at 26.5 degrees North for the 11 year period 1986 1997 in the western boundary system of the Atlantic Ocean. The overall focus will be on the nature and variability of deep recirculation, current structure and transport on interannual time scales in relation to large scale forcing changes such as the North Atlantic Oscillation (NAO). Investigators will collaborate with NOAA scientists at the Atlantic Oceanographic and Meteorological Laboratories. Specific objectives are to: 1 . Determine the mean transport structure east of the Bahamas, including the western boundary currents and deep recirculations extending to 600 km offshore 2. Investigate variability on interannual time scales and its relationship to basinwide wind forcing and changes in high latitude convective activity related to the NAO, 3. Improve estimates of the meridional ocean heat transport in the subtropical Atlantic and its annual and interannual variability using the current meter data along with Florida Current and interior XBT (EXpendable BathyThermograph) section data, and 4. Compare the current meter results with high resolution general circulation models.
