Abstract: The Huaihe River Basin is a typical climate transition region. It is rather important to study the water and energy cycle in this zone. This paper not only reviews the general situation of global energy and water cycle, but also designs the observation scheme of each water cycle’s link. At the same time, on the basis of American global precipitation measurement (GPM) and Olympic Mountain experiment (OLYMPEX), this artical presents the goal and specific implementation plan of the water and energy cycle experiment in Huaihe River Basin. Which provides a new train of thought for the establishment of the climate observatory observation network for the future in the Huaihe River Basin.
