Dr. Sellers will carry out detailed numerical experiments based on doubled carbon dioxide loading of the atmosphere, using the University of Arizona's climate model. This model-type falls between the full general circulation model (GCM) and a simple energy balance model and thus facilitates rapid model integrations for long time periods while retaining some of the important features of a more complex model. Focus of the numerical work will be on systematic investigation of the CO2 - doubling sensitivity of the model to all of the parameterizations in the model. This would aid in our understanding of factors that contribute to the global temperature sensitivity, which for GCMs may range from 2.8C to 5.2C depending upon the model. The results of this work would help pin down those processes that need to be very accurately modeled or parametarized.

塞勒斯博士将利用亚利桑那大学的气候模型，在大气中二氧化碳负荷加倍的基础上进行详细的数值实验。这种模式类型介于完全大气环流模式(GCM)和简单的能量平衡模式之间，因此有助于在长时间内快速整合模式，同时保留更复杂模式的一些重要特征。数值工作的重点将是系统地研究模式对模式中所有参数化的二氧化碳倍增敏感性。这将有助于我们理解影响全球温度敏感性的因素，根据模型的不同，全球温度敏感性可能在2.8摄氏度到5.2摄氏度之间。这项工作的结果将有助于确定那些需要非常准确地建模或参数化的过程。
