RAPID-WATCH is providing a unique continuous observational time series of the Atlantic meridional overturning circulation (MOC) at 26 N for the first time. The crucial question in this proposal is the link between the MOC and meridional heat transport (MHT) from the RAPID-WATCH observing system and the variability of oceanic heat content in the whole of the North Atlantic inferred from Argo floats. We have strong evidence that the ocean heat content variability from seasonal to interannual time scales (months-10 years) is mainly in the upper 2000 m of the ocean, and therefore can be sampled using the Argo floats. Argo is an international experiment to measure the temperature and salinity of the upper 2000 m of the global ocean using over 3000 profiling floats. Understanding the links between the full depth monitoring of the MOC at 26 N and the heat content of the upper 2000m of the North Atlantic is important. For example, a decrease in heat transport at 26 N and a normal heat transport at the latitude of UK, would lead to cooling of the ocean between these two latitudes, which could influence the strength of westerly winds and alter the temperature and rainfall patterns over the UK and Northern Europe.

Rapid-Watch首次在26 N时提供了大西洋子午翻转循环（MOC）的独特连续观察时间序列。该提案中的关键问题是从快速观察系统中的MOC和子午热传输（MHT）之间的联系，以及从Argo Floats推断出的整个北大西洋中海洋热含量的变化。我们有强有力的证据表明，从季节性到年际时间尺度（数月10年）的海热含量变异性主要在2000 m的海洋上部，因此可以使用Argo Floats进行采样。 Argo是一项国际实验，可利用3000多个分析浮子来测量全球海洋上部2000 m的温度和盐度。了解MOC在26 N处的全部深度监测与北大西洋上部2000m的热量含量之间的联系很重要。例如，在26 N处的热传输减少和英国纬度的正常热传输将导致这两个纬度之间的海洋冷却，这可能会影响西风的强度，并改变英国和北欧的温度和降雨模式。
