中文简介: | 世界上大约有十几个研究所正在开发和改进综合气候模型。每个模型都提供了对观测到的气候的合理模拟,每个模型都有其自身的优缺点。在目前的多模型集成方法中,模型仿真是独立进行的,其结果是由一个后验组合而成的。最近,有人提议在模拟过程中交互耦合模型,并将其作为一个超级模型运行。在这里,我们回顾了在中小型动力系统背景下的超模方法,并讨论了这种方法可能的优点。 |
课程简介: | At a dozen or so institutes around the world, comprehensive climate models are being developed and improved. Each model provides reasonable simulations of the observed climate, each with its own strengths and weaknesses. In the current multi-model ensemble approach model simulations are performed independently and their results are combined a posteriori. Recently, it has been proposed to couple models interactively during simulation and run this as one supermodel. Here we review the supermodel approach in the context of small and medium sized dynamical systems, and discuss the possible merits of the approach. |
