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.

该项目将研究植被过程（土地使用变化）和东亚的雪覆盖的作用，尤其是在藏族高原上，通过调节热梯度和BOWEN比率来影响季风的演变，这是陆地表面的传输或梯度方程的比率）。耦合的一般循环模型和简化的简单生物圈模型将用于执行跨越1982 - 2001年期间的20年运行。该项目促进了美国和中国之间的国际合作，还提供了对其他不可用的数据集的访问权限，以促进模型验证。工作中包括一个重要的学生培训组成部分，预计该项目将在以前被忽视的研究领域做出重大贡献。
