青藏高原能量与水循环过程对我国、东亚乃至全球的天气和气候系统都有着非常重要的作用。1996年以来，在国家自然科学基金委员会、中国科学院、中国气象局等相关部门和日本政府的大力支持下，我们针对青藏高原能量和水循环过程的重要性，成功地开展了青藏高原尺度和藏北地区中尺度的“全球能量水循环之亚洲季风青藏高原试验研究”(GAME/Tibet)项目和“全球协调加强观测计划之亚澳季风青藏高原试验研究”(CAMP/Tibet)项目近10余年的连续观测，取得了以往高原试验从未有过的大量极其珍贵的综合观测资料。而且在利用试验资料分析、卫星遥感及数值模拟等手段研究青藏高原能量与水循环方面取得大量的阶段性成果。介绍了青藏高原能量与水循环的研究进展及国际合作在项目执行过程中所起到的作用，同时介绍国际合作在吸纳境外研究资源及培养青年科技人才中所起的作用。最后提出了国际合作中存在的问题，并给出了相关的建议。

The processes of energy and water cycle over the Tibetan Plateau have shown that the giant prominence exerts thermal effects on the atmosphere, thus greatly influencing atmospheric circulations over China, Asia and even the globle. Focusing on this issue, the intensive observation period (IOP) and long-term observation of the GEWEX (Global Energy and Water cycle Experiment) Asian Monsoon Experiment on the Tibetan Plateau ( GAME/Tibet ) and CEOP (Coordinated Enhanced Observing Period) Asia Australia Monsoon Project (CAMP) on the Tibetan Plateau (CAMP/ Tibet ) have been carried out successfully from the beginning of 1996 under the support of National Natural Science Foundation of China (NSFC), the Chinese Academy of Sciences(CAS), the China Meteorological Administration(CMA) and the Japanese government etc. A large number of data has been collected, which is the best data set so far for the study of energy and water cycle over the Tibetan Plateau. Great progress has been made in the study of energy and water cycle over the Tibetan Plateau through the in-situ data analysis, satellite remote sensing parameterization and the numerical modeling, etc. The progresses of  the study of energy and water cycle over the Tibetan Plateau and the role of the international cooperation in the projects will be introduced in detail. The role of the international cooperation in getting the research found from abroad and in training young scientists and students is also mentioned. The existing problems in the international cooperation and the solving ways are presented in the paper at the same time.
