North west Europe has a relatively mild climate in part because of heat pulled north through the Atlantic by the overturning. There is a risk that global warming will cause this circulation to rapidly decrease with consequences involving not only colder winters for Europe but also changes in sea level and precipitation. This project will carry out a risk assessment of rapid changes of the Atlantic overturning. We will use two models of the climate system, HADCM3, the Hadley Centre model used in the IPCC AR4, and CHIME, a global climate model developed at the National Oceanography Centre, Southampton. This has the same atmospheric model as HADCM3 but has a very different structure to the ocean component. Making use of the resources of climateprediction.net we will run a large ensemble of both models to assess the uncertainties in the system. We will then use modern Bayesian statistical techniques to combine model output, data and expert opinion in our risk assessment. The utility of the data from the RAPID-WATCH arrays is an important aim of the project.

西北欧的气候相对温和，部分原因是由于倾覆而北部穿过大西洋。有风险，全球变暖会导致这种循环迅速减少，而后果不仅涉及欧洲冷冬季，而且还会改变海平面和降水量。该项目将对大西洋推翻的快速变化进行风险评估。我们将使用两种模型的气候系统，Hadcm3，IPCC AR4中使用的Hadley Center模型，以及在南安普敦国家海洋学中心开发的全球气候模型Chime。这与HADCM3具有相同的大气模型，但与海洋组件的结构非常不同。利用气候Prediction.net的资源，我们将运行大量的两种模型，以评估系统中的不确定性。然后，我们将使用现代贝叶斯统计技术在风险评估中结合模型输出，数据和专家意见。快速观察阵列中数据的实用性是该项目的重要目的。
