LEGACY: Labrador Current Governs North Atlantic Climate System?

了解北大西洋气候系统在未来几十年将如何变化，以及这将如何影响英国，是社会面临的一个关键环境挑战。我们需要能够更好地预测我们的气候和极端天气将如何在我们的政府可以规划的时间尺度上发生变化，这意味着更好地了解导致我们的气候系统在十年时间尺度上发生变化的机制。我们还必须确保我们用于预测的气候模型能够正确地代表这些过程。我们的愿景是揭示北大西洋气候系统十年变化的新机制，其中涉及拉布拉多海流的变化。这是一股从拉布拉多海岸向南流动的冷淡水，它可能会导致北大西洋的大规模变化。我们将研究这些变化如何影响我们气候系统的十年时间尺度变化，通过使用我们最新的，最先进的气候模型之一，并得到可用观测的支持。因此，预计该项目将导致对气候系统的新的和创新的见解。

Understanding how the North Atlantic Climate System will change in the next few decades, and how this will impact the UK, is a key environmental challenge facing society. We need to be able to better predict how our climate and weather extremes will change on timescales which our Government can plan for, and this means developing a better understanding of the mechanisms causing changes in our climate system on decadal timescales. We must then also ensure that the climate models which we use for our predictions are able to properly represent these processes. Our vision is to uncover a new mechanism for decadal variability in the North Atlantic climate system which involves changes in the Labrador Current. This is a southward flow of cold, fresh water off the Labrador coast, and which can cause large-scale changes in the North Atlantic Ocean. We will examine how such changes might affect decadal-timescale changes in our climate system, by using one of our latest, state-of-the-art climate models, backed up with available observations. The project is therefore expected to lead to new and innovative insights into the climate system.
