Assimilation in ocean and coupled models to determine the thermohaline circulation.

为了最大限度地利用历史考察船记录以及来自自主海洋剖面浮标和快速气候变化等特殊观测计划的新观测数据，建议将过去40年的所有可用数据同化到一个高质量的海洋环流模式中，该模式可以代表完整的海洋属性场。通过这种方式，还可以确定诸如南北质量和热量传输等推导出的量，这些量对于理解海洋在控制气候中的作用至关重要。该项目还将结合从地方区域汇编的各种观测时间序列，这些时间序列表明海洋环流和运输在过去几十年中一直在发生重大变化。因此，这些时间序列将被放在正在发生变化的流域和全球范围内。该计划将确定海洋盆地(特别是北大西洋)不同部分的水文信号之间的关系。该方案还将提供一种方法，将来自温盐监测阵列的数据同化成海洋模型，然后将其用作多年期气候预测的耦合气候模型的一部分。

To make the best use of the historical research ship records as well as new observations from autonomous ocean profiling floats and special observing programs such as Rapid climate change, it is proposed to assimilate all of the available data from the past 40 years into a high quality ocean circulation model that can represent complete fields of ocean properties. In this way derived quantities such as the north-south mass and heat transports which are vital to understanding the oceans role in controlling climate, can also be determined. The project will also put into context the various timeseries of observations that have been compiled from local regions which suggest that important changes in ocean circulation and transports have been ongoing in the past decades. These timeseries will thus be put into a basin scale and global scale context of ongoing change. The program will determine the relationship between hydrographic signals in different parts of the ocean basins (particularly the N Atlantic). The program will also provide a method for assimilating data from the thermohaline monitoring arrays into an ocean model that could then be used as part of a coupled climate model for multi-annual climate prediction.
