ABSTRACT ATM 97-11492 Liu , Zhengyu U WISC TITLE: Multi-component Response of the Tropical Atmosphere Vegetation System to CO2 Increase The response of the global climate and biosphere to the increase of CO2 is a major concern for the future. The behavior of the tropical atmosphere/ocean/vegetation system is of particular importance because a very significant fraction of the world's population lives in the tropics, and changes in climate, and in food and water resources will have important societal consequences. The linkages between the long term atmosphere- ocean- vegetation response to CO2 increases, and the additional impact of massive tropical deforestation, require analysis of complex, multi-component models. The PIs will conduct these studies using state of the art climate model, the NCAR Community Climate Model, linked to a terrestrial vegetation model. They will use a relatively new methodology, equilibrium asynchronous coupling, to help diagnose the effects of changes in component on the other components. The new coupling method if tested successful will result in significant economy of computational time needed to run ensembles of model simulations that are generally needed in climate research. This award is funded under the NSF Methods and Models for Integrated Assessments initiative.

摘要ATM 97-11492刘正宇 U WISC 标题：热带大气植被系统对CO2增加的多成分响应 全球气候和生物圈对CO2增加的反应是未来的一个主要问题。 热带大气/海洋/植被系统的行为特别重要，因为世界人口的很大一部分生活在热带地区，气候、食物和水资源的变化将产生重要的社会后果。 大气-海洋-植被对CO2增加的长期反应与大规模热带森林砍伐的额外影响之间的联系需要对复杂的多成分模型进行分析。 PI将使用最先进的气候模型进行这些研究，NCAR社区气候模型与陆地植被模型相关联。 他们将使用一种相对较新的方法，平衡异步耦合，以帮助诊断组件中的变化对其他组件的影响。新的耦合方法，如果测试成功，将导致显着的经济计算所需的时间来运行模式模拟，在气候研究中通常需要的合奏。 该奖项由NSF综合评估方法和模型倡议资助。
