实施本重大研究计划，旨在揭示青藏高原对全球气候及其变化的影响机制；认识青藏高原地-气耦合过程、青藏高原云降水及水循环过程以及对流层-平流层相互作用过程；建立青藏高原资料库和同化系统；完善青藏高原区域和全球气候系统数值模式；揭示青藏高原影响区域与全球能量和水分循环的机制。 . 将青藏高原影响区域、全球气候的机理作为研究主线，模式与分析技术作为支撑，以实现理论与应用技术的跨越。促进高原前沿理论研究与大气科学观测试验的有机结合，推进国际前沿性研究领域的创新研究。

The implementation of this major research program is aimed at: revealing the mechanism of the Tibetan Plateau’s impacts on the global climate and climate change; understanding the land-air coupling processes, cloud precipitation, water cycle and their interactions with troposphere-stratosphere over the plateau; establishing a Tibetan Plateau database and a data assimilation system; improving the Tibetan Plateau regional climate models and global climate system models; and identifying the mechanism of the plateau’s influences on regional and global energy and water circle.. As the main thrust, being supported by models and analysis tools, the research work on mechanism of the Tibetan Plateau’s impacts on regional and global climate will help bridge the gap between theoretical findings and applied techniques. It will be well combined with forefront theoretical research and atmospheric observation experiment, and it will advance the innovative research in world cutting-edge research areas.
