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首次提供了北纬26度大西洋纬向翻转环流（MOC）的独特连续观测时间序列。这一建议的关键问题是快速观察观测系统的MOC和对流热输送与阿尔戈浮标推断的整个北大西洋海洋热含量的变化之间的联系。我们有强有力的证据表明，从季节到年际时间尺度（月至10年）的海洋热含量变化主要是在海洋的上部2000米，因此可以使用Argo浮标进行采样。阿尔戈是一项国际实验，使用3000多个剖面浮标测量全球海洋上层2000米的温度和盐度。了解26 N处MOC的全深度监测与北大西洋上部2000米的热含量之间的联系是重要的。例如，26 N处的热传输减少和英国纬度处的正常热传输将导致这两个纬度之间的海洋冷却，这可能影响西风的强度，并改变英国和北方欧洲的温度和降雨模式。
