利用高斯-牛顿线搜索优化算法对Hadley中心大气模式（HadAM 3）第3版的扰动物理配置进行了调整，使之与外辐射观测值相匹配。先前的研究发现影响气候敏感性的四个关键参数被调整到几个不同的目标值，包括两组观测结果。使用的观测数据是云层和地球辐射能系统仪器反射的全球平均短波辐射和向外长波辐射，并结合海洋热含量观测数据。使用同样的方法，还生成了与早期地球辐射收支实验结果一致的配置。许多，虽然不是全部，调谐实验是成功的，约2500配置被生成和模拟出射辐射的变化主要是由于在clou...
AbstractPerturbed physics configurations of version 3 of the Hadley Centre Atmosphere Model (HadAM3) driven with observed sea surface temperatures (SST) and sea ice were tuned to outgoing radiation observations using a Gauss–Newton line search optimization algorithm to adjust the model parameters. Four key parameters that previous research found affected climate sensitivity were adjusted to several different target values including two sets of observations. The observations used were the global average reflected shortwave radiation (RSR) and outgoing longwave radiation (OLR) from the Clouds and the Earth's Radiant Energy System instruments combined with observations of ocean heat content. Using the same method, configurations were also generated that were consistent with the earlier Earth Radiation Budget Experiment results. Many, though not all, tuning experiments were successful, with about 2500 configurations being generated and the changes in simulated outgoing radiation largely due to changes in clou...
