Major changes are occurring across the North Atlantic climate system: in oceanic and atmospheric temperatures and circulation, in sea ice thickness and extent, and in key atmospheric constituents such as ozone, methane and particles known as aerosols. Many observed changes are unprecedented in instrumental records. Changes in the North Atlantic directly affect the UK's climate, weather and air quality, with major economic impacts on agriculture, fisheries, water, energy, transport and health. The North Atlantic also has global importance, since changes here drive changes in climate, hazardous weather and air quality further afield, such as in North America, Africa, and Asia.The ACSIS extension is a 1 year continuation of an ongoing 5-year strategic research programme called ACSIS: the North Atlantic Climate System Integrated Study.ACSIS brings together and exploits a wide range of capabilities and expertise in the UK environmental science community. Its goal is to enhance the UK's capability to detect, attribute (i.e. explain the causes of) and predict changes in the North Atlantic Climate System. ACSIS is delivering new understanding of the North Atlantic climate system by integrating new and old observations of atmospheric physics and chemistry, of the ocean state and of Arctic ice, complemented by detailed data analysis and state-of-the-art computer simulations. Observations are obtained from diverse sources including NERC's observational sites in the North Atlantic, satellite remote sensing and the NCAS FAAM aeroplane. The computer modelling component is providing simulations of the atmosphere, ocean, and sea ice with unprecedented spatial detail.The ACSIS extension will exploit advances made during the past 5 years to address specific new research questions which have arisen recently. It will investigate exciting evidence that changes in the climate of the North Atlantic/European region are much more predictable than was previously thought and will start to assess the impact of North Atlantic changes on the UK environment.

整个北大西洋气候系统正在发生重大变化：海洋和大气温度和环流、海冰厚度和范围，以及臭氧、甲烷和气溶胶颗粒等关键大气成分。许多观察到的变化在乐器记录中是前所未有的。北大西洋的变化直接影响英国的气候、天气和空气质量，对农业、渔业、水、能源、交通和健康产生重大经济影响。北大西洋也具有全球重要性，因为这里的变化会导致更远地区（例如北美、非洲和亚洲）的气候、恶劣天气和空气质量的变化。ACSIS 延期是正在进行的 5 年战略的延续 1 年名为 ACSIS 的研究计划：北大西洋气候系统综合研究。ACSIS 汇集并利用了英国环境科学界的广泛能力和专业知识。其目标是增强英国检测、归因（即解释其原因）和预测北大西洋气候系统变化的能力。 ACSIS 通过整合大气物理和化学、海洋状态和北极冰的新旧观测，并辅以详细的数据分析和最先进的计算机模拟，提供对北大西洋气候系统的新认识。观测数据来自不同来源，包括 NERC 位于北大西洋的观测站、卫星遥感和 NCAS FAAM 飞机。计算机建模组件提供了对大气、海洋和海冰的模拟，具有前所未有的空间细节。ACSIS 扩展将利用过去 5 年取得的进展来解决最近出现的具体新研究问题。它将调查令人兴奋的证据，证明北大西洋/欧洲地区的气候变化比之前想象的更容易预测，并将开始评估北大西洋变化对英国环境的影响。
