摘要新的哈德利中心全球环境模式（HadGEM 1）的大气部分的性能进行评估，其能力，以代表一个选择的关键方面的变化，在热带和热带外。这些包括中纬度风暴路径和阻塞活动，欧洲上空的天气变率，北大西洋涛动以及热带对流，马登-朱利安涛动和亚洲夏季风。与以前的模型，第三哈德利中心耦合海洋-大气GCM（HadCM 3）的比较表明，有一个相当大的增加瞬态涡动动能（EKE），使HadGEM 1到更接近的协议与当前的再分析。EKE的这种增加是由于水平分辨率的提高，并与改进的物理参数化相结合，导致北方半球风暴路径和阻塞的代表性的改善。欧洲天气系统的模拟是一个...
Abstract The performance of the atmospheric component of the new Hadley Centre Global Environmental Model (HadGEM1) is assessed in terms of its ability to represent a selection of key aspects of variability in the Tropics and extratropics. These include midlatitude storm tracks and blocking activity, synoptic variability over Europe, and the North Atlantic Oscillation together with tropical convection, the Madden–Julian oscillation, and the Asian summer monsoon. Comparisons with the previous model, the Third Hadley Centre Coupled Ocean–Atmosphere GCM (HadCM3), demonstrate that there has been a considerable increase in the transient eddy kinetic energy (EKE), bringing HadGEM1 into closer agreement with current reanalyses. This increase in EKE results from the increased horizontal resolution and, in combination with the improved physical parameterizations, leads to improvements in the representation of Northern Hemisphere storm tracks and blocking. The simulation of synoptic weather regimes over Europe is a...
