Collaborative Research: Observations and Models of Upper Ocean Water Mass Formation and Evolution in the Western North Atlantic

为研究北大西洋西部18度水（EDW）的形成提供了支持，那里从海洋到大气的热通量与世界上任何地方的地表热通量一样大或更大。通过使用来自大西洋环流和气候实验（ACCE）的PALACE浮标数据，从机遇号船上收集的XBT数据，以及使用MICOM等平坐标数值模型进行的一系列研究，将解决EDW的俯冲、环流环流和时间变化问题。对观测结果和模式输出的综合分析将集中在确定EDW形成的地点、确定EDW的性质、量化某一年形成的EDW量、EDW形成的大尺度环流影响及其与气候现象的关系。这一建议是对世界海洋环流实验（WOCE）的分析、解释、综合和模拟阶段的贡献。

Support is provided to study the formation of eighteen-degree water (EDW) in the western North Atlantic, where the heat flux from the ocean to the atmosphere is as large as or larger than the surface heat flux anywhere in the world. Subduction, circulation around the gyre, and temporal variability of the EDW would be addressed using PALACE float data from the Atlantic Circulation and Climate Experiment (ACCE), XBT data collected from ships of opportunity, and a series of studies using the MICOM isopycnal coordinate numerical model. The combined analyses of the observations and model output will focus on the identification of the sites of EDW formation, the identification of EDW properties, the quantification of the amount of EDW formed for a given year as well as large scale circulation impacts of EDW formation and its relation to climate phenomena. This proposal is a contribution to the Analysis, Interpretation, Synthesis and Modeling phase of the World Ocean Circulation Experiment (WOCE).
