项目摘要

Major changes are occurring across the North Atlantic climate system: in ocean and atmosphere 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.ACSIS is a 5 year strategic research programme that brings together and exploits a wide range of capabilities and expertise in the UK environmental science community. It's 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 will deliver new understanding of the NA climate system by integrating new and old observations of atmospheric physics and chemistry, of the ocean state and of Arctic Ice. The observations will be complemented by detailed data analysis and numerical simulations. Observations will come from existing networks, from NERC's own observational sites in the North Atlantic, and from space. Seasonal surveys using the NCAS FAAM aeroplane will further enhance our observational strategy. A key dimension of the observational opportunity is that data records of sufficient length, for multiple variables, are becoming available for the first time. The modelling component will involve core numerical simulations with cutting-edge atmosphere, ocean, sea ice, chemistry and aerosol models using the latest parameterizations and unprecedented spatial detail, as well as bespoke experiments to investigate specific time periods or to explore and explain particular observations. ACSIS will provide advances in understanding and predicting changes in the NA climate system that can be exploited to assess the impact of these changes on the UK and other countries - for example in terms of the consequences for hazardous weather risk, the environment and businesses. ACSIS outputs will also inform policy on climate change adaptation and air quality.

北大西洋气候系统正在发生重大变化：在海洋和大气温度和循环中，海冰厚度和程度以及关键的大气成分中，例如臭氧，甲烷和称为气溶胶的颗粒。在工具记录中，许多观察到的变化是前所未有的。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，运输和健康产生重大的经济影响。北大西洋也具有全球重要性，因为这里的变化推动了气候，危险的天气和空气质量的变化，例如在北美，非洲和亚洲。ACSIS是一项为期5年的战略研究计划，它汇集并利用了英国环境科学社区的广泛能力和专业知识。它的目标是增强英国检测，属性（即解释原因）的能力，并预测北大西洋气候系统的变化。 ACSIS将通过整合大气物理和化学，海洋国家和北极冰的新的和古老的观察结果，对NA气候系统进行新的了解。这些观察结果将通过详细的数据分析和数值模拟来补充。观察结果将来自现有网络，来自NERC自己的北大西洋观察站点以及空间。使用NCAS FAAM飞机的季节性调查将进一步增强我们的观察策略。观察机会的一个关键维度是，对于多个变量，足够长的数据记录首次可以使用。该建模组件将使用最新的参数化和前所未有的空间细节，以及定制的实验，以研究特定时间段或探索和解释特定的观察结果，并使用最新的参数化和前所未有的空间细节以及定制的实验，涉及核心数值模拟，海洋，海冰，化学和气溶胶模型。 ACSIS将在理解和预测NA气候系统变化方面提供进步，以评估这些变化对英国和其他国家的影响 - 例如，就危险天气风险，环境和企业的后果而言。 ACSIS输出还将为气候变化适应和空气质量提供信息。
