Using a newly-developed ocean model that harnesses the power of graphical processing units (GPUs) instead of the common central processing units (CPUs) we can run global ocean simulations at 1/50th the cost. Utilising this speed up, we aim to pioneer a modelling framework to perform ensembles of eddy-resolving global ocean simulations under various climate-change scenarios. This ensemble approach will enable us to separate the changes we see in future projections that are due to climate change from the changes that occur in the due to the natural variations of the climate system. The project's outcomes will increase our confidence in future climate change projections, including ocean heat uptake, and sea level rise.

使用新开发的海洋模型，利用图形处理单元（GPU）而不是常见的中央处理单元（CPU）的功能，我们可以以1/50的成本运行全球海洋模拟。利用这种加速，我们的目标是开创一个建模框架，在各种气候变化情景下执行涡流解决全球海洋模拟的集合。这种总体方法将使我们能够将我们在未来预测中看到的由于气候变化而引起的变化与由于气候系统的自然变化而发生的变化分开。该项目的成果将增加我们对未来气候变化预测的信心，包括海洋热量吸收和海平面上升。
