Modeling the Meridional Overturning Circulation (MOC) in the North Atlantic: Seasonal to Decadal Variability

9531852该项目是对将作为世界海洋环流实验下的大西洋环流和气候实验的一部分进行的模拟部分的贡献。重点将放在升级现有等温模式、数据同化和整合不同类型的区域模式上。将对不同的模拟方法进行比较，以评估每种方法的优缺点，并确定将海洋变异性纳入气候模拟的最佳总体方法。将特别注意将非洲气候变化中心实地阶段的数据以及历史数据库的数据纳入模型。在这个特别的项目中，PI将利用迈阿密等轴线坐标海洋模式(MICOM)进行一系列数值实验，研究北大西洋经向翻转环流对强迫和边界条件变化的敏感性。将对季节和年代际变化进行具体应用。

9531852 Chassignet This project is a contribution to the modeling component to be carried out as part of the Atlantic Circulation and Climate Experiment (ACCE) under the World Ocean Circulation Experiment (WOCE). The focus will be on upgrading existing isopycnal models, data assimilation, and integrating different types of regional models. Comparisons will be made among different modeling approaches in order to assess the strngths and weaknesses of each, and to determine the best overall approach for including ocean variability in climate modeling. Particular attention will be paid to assimilating, into the models, data from the field phase of ACCE, as well as from historical data bases. In this particular project, the PI will investigate the sensitivity of the North Atlantic meridional overturning circulation to changes in forcing and boundary conditions in a series of numerical experiments using the Miami Isopycnic Coordinate Ocean Model (MICOM). Specific applications will be made to seasonal and decadal variability.
