Multi-component Response of the Tropical Atmosphere/Ocean/Vegetation System to CO2 Increase

标题：热带大气植被系统对CO2增加的多组分响应全球气候和生物圈对CO2增加的响应是未来关注的主要问题。热带大气/海洋/植被系统的行为特别重要，因为世界上很大一部分人口生活在热带地区，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-植被对二氧化碳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组分模式进行分析。pi将使用最先进的气候模型NCAR社区气候模型进行这些研究，该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，来帮助诊断组件更改对其他组件的影响。如果测试成功，这种新的耦合方法将大大节省运行气候研究中通常需要的模式模拟集合所需的计算时间。该奖项由美国国家科学基金会综合评估方法和模型计划资助。

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.
