The large scientific experiments for the process of the energy and water cycle are introduced. It is more and more clear that the study for the process of the energy and water cycle is the research focus on climatology henceforth. The arm of experiments is to further understand the physical process of the climatic changes e.g. The green house effect by simulation and analysis of the heat/water exchange among air land ocean. The experiments can be expected for solving the problem about the forecast floods and drought around East Asia.
