RAPID Circulation Overflow and Deep Convection Studies in the Nordic Seas Tracers and Models data

"The Circulation, overflow, and deep convection studies in the Nordic Seas using tracers and models" project was a Natural Environment Research Council (NERC) RAPID Climate Change Research Programme project (Round 1 - NER/T/S/2002/00446 - Duration 1 Aug 2003 - 31 Oct 2006 ) led by Prof Andrew Watson of the University of East Anglia, also with co-investigators at the University of East Anglia. Dataset contains sources of water in the Greenland-Scotland overflows: recent tracer release and transient tracer observations, as well as the initiation of convection and its relation to submesoscale hydrodynamics. This dataset collection contains MIT General Circulation Model (MITgcm) ocean model basin and channel experiment outputs. The project investigated two aspects of the Nordic Seas circulation of importance to the North Atlantic meridional overturning circulation (MOC): (1) Sources of water in the Greenland-Scotland overflows: recent tracer release and transient tracer observations were used to constrain inverse models of the sources of Denmark Straits and Faroe-Bank channel overflow waters. (2) The initiation of convection and its relation to submesoscale hydrodynamics: very high-resolution non-hydrostatic models for the Central Greenland Sea were used to model recent observations, which show convection to be intimately related to local sub-mesoscale structure.: The objective was to develop improved descriptions of convection for use in OGCMs, to more accurately describe how the sinking branch of the MOC will be affected by changes in forcing. Rapid Climate Change (RAPID) was a £20 million, six-year (2001-2007) programme for the Natural Environment Research Council. The programme aimed to improve the ability to quantify the probability and magnitude of future rapid change in climate, with a main (but not exclusive) focus on the role of the Atlantic Ocean's Thermohaline Circulation."基于示踪剂与数值模式的挪威海环流、溢流与深对流研究"项目，是自然环境研究委员会（Natural Environment Research Council, NERC）RAPID气候变化研究计划（第1轮，项目编号NER/T/S/2002/00446，执行周期为2003年8月1日至2006年10月31日）资助项目，由东安格利亚大学安德鲁·沃森教授牵头，共同研究者亦来自东安格利亚大学。本数据集涵盖格陵兰-苏格兰溢流的水源相关数据：包括最新的示踪剂释放与瞬态示踪剂观测资料，以及对流起始过程及其与亚中尺度水动力的关联内容。 本数据集合集包含麻省理工学院通用环流模式（MIT General Circulation Model, MITgcm）的大洋模式海盆与通道试验输出结果。 该项目针对与北大西洋经向翻转环流（North Atlantic meridional overturning circulation, MOC）密切相关的挪威海环流展开了两项核心研究：(1) 格陵兰-苏格兰溢流的水源：通过最新示踪剂释放与瞬态示踪剂观测资料，约束丹麦海峡与法罗浅滩通道溢流水源的反演模式；(2) 对流起始过程及其与亚中尺度水动力的关联：针对格陵兰海中部采用超高分辨率非静力模式复刻最新观测结果，研究显示对流过程与局地亚中尺度结构存在紧密关联。本研究的目标是为大洋通用环流模式（Ocean General Circulation Models, OGCMs）优化对流过程的描述方案，进而更精准地刻画经向翻转环流（MOC）下沉分支如何受强迫变化的影响。 RAPID气候变化研究计划（RAPID）是自然环境研究委员会资助的一项总投入达2000万英镑、为期六年（2001-2007年）的研究计划，旨在提升对未来气候快速变化的概率与强度的量化能力，核心（但非唯一）研究方向为大西洋热盐环流的作用。
