摘要。FAMOUS是一个低分辨率的海洋-大气环流模式，能够使用当前的高性能计算设备模拟每个时钟日大约120年的模式气候。它使用的大部分代码与HadCM3相同，HadCM3是一种广泛使用的气候模型，具有更高的分辨率和计算成本，并且经过调整可以相当好地再现相同的气候。FAMOUS对于气候模拟是有用的，在这种情况下，计算成本使得HadCM3的应用不可行，要么是因为模拟的长度，要么是因为所需集合的大小。我们记录了对FAMOUS原始版本的一些科学和技术改进。这些改进包括臭氧和海冰参数化的变化，这些变化减轻了来自北纬高纬度和对流层上层的显著偏冷，以及消除了海洋示踪剂的体积平均漂移。其中还包括一个简单的海洋碳循环模型。FAMOUS的一个特别目标是进行第四纪冰期千年尺度的古气候模拟；为此，对模型基础结构进行了许多有用的更改。
Abstract. FAMOUS is an ocean-atmosphere general circulation model of low resolution, capable of simulating approximately 120 years of model climate per wallclock day using current high performance computing facilities. It uses most of the same code as HadCM3, a widely used climate model of higher resolution and computational cost, and has been tuned to reproduce the same climate reasonably well. FAMOUS is useful for climate simulations where the computational cost makes the application of HadCM3 unfeasible, either because of the length of simulation or the size of the ensemble desired. We document a number of scientific and technical improvements to the original version of FAMOUS. These improvements include changes to the parameterisations of ozone and sea-ice which alleviate a significant cold bias from high northern latitudes and the upper troposphere, and the elimination of volume-averaged drifts in ocean tracers. A simple model of the marine carbon cycle has also been included. A particular goal of FAMOUS is to conduct millennial-scale paleoclimate simulations of Quaternary ice ages; to this end, a number of useful changes to the model infrastructure have been made.
