The 'Atlantic Meridional Overturning Circulation', or AMOC, describes a large scale circulation of the North Atlantic Ocean which carries warm surface waters northward and cooler deeper waters southwards. This circulation carries huge amounts of heat, and variations in its strength can have a substantial influence on European climate. The DYNAMOC project aims to improve understanding of how this circulation has varied in the past and how it has affected climate, and also to assess the potential for useful predictions months to years ahead. DYNAMOC will make use of new advanced computer simulations and forecasting systems which are able to simulate the AMOC in unprecedented detail. It will also make use of the RAPID observations of the AMOC strength at 26 degrees North, available since 2004, as a benchmark for testing the models and predictions. The research will test some specific hypotheses about how the AMOC works, how it is changing now. It will investigate how a slow down or speed up in the AMOC affects summers and winters in the UK and other countries. DYNAMOC will provide an assessment of the likely behaviour of the AMOC, and its impacts on climate, over the next decade. It will also produce recommendations for improving forecasting systems in the future.DYNAMOC is a collaboration between the National Centre for Atmospheric Science at the University of Reading, the National Oceanography Centre and the UK Met Office.

“大西洋经向翻转环流”（AMOC）描述了北大西洋的一个大规模环流，它将温暖的表层水向北输送，将较冷的深层水向南输送。这种环流携带着大量的热量，其强度的变化会对欧洲的气候产生重大影响。DYNAMOC项目旨在提高对这种环流在过去如何变化以及它如何影响气候的理解，并评估未来几个月到几年有用预测的潜力。DYNAMOC将利用新的先进的计算机模拟和预报系统，能够以前所未有的细节模拟AMOC。它还将利用2004年以来对北纬26度AMOC强度的RAPID观测，作为测试模型和预测的基准。这项研究将测试一些关于AMOC如何运作的具体假设，以及它现在是如何变化的。它将调查AMOC的减速或加速如何影响英国和其他国家的夏季和冬季。DYNAMOC将对未来十年AMOC的可能行为及其对气候的影响进行评估。它还将为今后改进预报系统提出建议。DYNAMOC是雷丁大学国家大气科学中心、国家海洋学中心和英国气象局的合作项目。
