Abstract: Field observation experiment is the most direct and effective method to study mountain meteorology, which plays an important role in revealing the various phenomena and related physical processes in the mountains, developing and improving the parameterization schemes for numerical model, verifying and evaluating the satellite remote sensing products, and improving the accuracy of weather forecast in mountain areas. In this paper, we briefly review the renowned field observation experiments, which were conducted over the Tibetan Plateau, Alps, Rocky Mountains, Sierra Nevada, Pyrénées, and other large-scale mountain areas. We then summarize the development trend of field observation experiment and associated investigation under complex terrain conditions at home and abroad, and recent progress in mountain meteorological monitoring in low latitude plateau region.Finally, we propose the importance of constructing high density meteorological observation system in complex mountainous areas.
