Abstract: This paper introduces the research progress of typical observation experiments in the field of weather modification in China, summarizes and discusses the problems of the experiments and puts forward some suggestions. It is mainly included with the research results on observation experiments and laboratory experiments of aerosol, cloud condensation nuclei, and ice nuclei.In addition, it also discusses the research results of cloud microphysics and precipitation observation experiments in different cloud systems. The study is conducive to an overall understanding of the progress made and limitations of weather modification observation experiment in China. It is expected to provide reference for the development of such observation experiment in China in the future.
