CAREER: Expanding Earth System Modeling Through Research and Education: An Integrated Assessment of Interactions between the Ocean, Atmosphere, Carbon Cycle and Climate Change

本项目利用二维综合科学评估模型（ISAM）解决了气候变化不确定性中的一些广泛问题。具体而言，主要目标是：(1)加强当前ISAM框架中的参数表示；(2)利用加强后的ISAM框架评估气候系统中涉及大气CO2、全球变暖、水循环、海洋环流、海洋碳循环等关键反馈过程的影响，以及它们对海洋碳吸收时空变化的贡献。重点将是研究温盐环流的可能变化及其对海洋生物学、海洋温度和示踪剂分布、大气CO2浓度演变和大气温度变化的影响。ISAM的结果将与其他二维和三维大气-海洋环流模式进行比较。这项研究有可能增加对影响大气中二氧化碳浓度水平的物理过程的认识和理解。这对于评估人类活动对气候变化的影响至关重要，气候变化是一个重要的社会问题。

This project addresses some broad issues in climate change uncertainties using a 2D Integrated Science Assessment Model (ISAM). In particular, the main objectives are to (1) strengthen parametric representation in the current ISAM framework, and (2) use the strengthened ISAM framework to evaluate the impact of key feedback processes within the climate system involving atmospheric CO2, global warming, the hydrological cycle, ocean circulation, the marine carbon cycle, and their contribution to spatial and temporal changes in ocean carbon uptake. A focus will be on the investigation of possible changes in the Thermohaline Circulation (THC) and its impact on ocean biology, on the distribution of temperature and tracers in the ocean, the evolution of the atmospheric CO2 concentration, and atmospheric temperature change.ISAM results will be compared with other 2-D and 3-D atmosphere-ocean general circulation models This research has the potential to increase knowledge and understanding of physical processes that influence the concentration levels of carbon dioxide in the atmosphere. This is turn is important for assessing the role of human-induced forcing on climate change, an important societal issue.
