This project will study the role of vegetation processes (changes in land use) and snow cover in East Asia, especially on the Tibetan Plateau, in influencing monsoon evolution by modulating the thermal gradients and Bowen ratio - a ratio of the transport or gradient equations of sensible heat and latent heat) at the land surface. A coupled general circulation model and Simplified Simple Biosphere Model will be used to perform a series of 20-year runs spanning the period 1982-2001. This project promotes international collaboration between the United States and China, also providing access to otherwise unavailable data sets to facilitate model verification. A significant student-training component is included in the work, and the project is expected to make a major contribution in a formerly neglected area of research.

该项目将研究东亚特别是青藏高原的植被过程（土地利用的变化）和积雪在通过调节地表的热梯度和鲍恩比（感热和潜热的输送或梯度方程的比值）影响季风演变方面的作用。一个耦合的大气环流模式和简化的简单生物圈模式将被用来执行一系列的20年运行跨越1982-2001年期间。该项目促进了美国和中国之间的国际合作，还提供了访问其他不可用的数据集，以促进模型验证。一个重要的学生培训部分包括在工作中，该项目预计将在一个以前被忽视的研究领域作出重大贡献。
