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，是社会面临的关键环境挑战。我们需要能够更好地预测我们的气候和天气极端情况将如何在我们的政府可以计划的时间尺度上发生变化，这意味着要更好地理解导致我们的气候系统在十年时间尺度上变化的机制。然后，我们还必须确保我们用于预测的气候模型能够适当地代表这些过程。我们的愿景是揭示北大西洋气候系统年代际变化的新机制，其中包括拉布拉多海流的变化。这是拉布拉多海岸外向南流动的冷淡水，可能会导致北大西洋发生大规模变化。我们将通过使用我们最新的、最先进的气候模型之一，并结合现有的观测数据，研究这种变化可能如何影响我们气候系统的十年时间尺度变化。因此，该项目有望为气候系统带来新的创新见解。

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.
