Abstract:Cryospheric Science, as an emerging interdisciplinary research field combining natural science and humanity, aims to understand nature's law, serve human society and promote sustainable development. In recent years, by deepening the understanding of the cryosphere elements and the whole sphere, and by expanding the application research of cryospheric science, the Chinese community of cryospheric science has developed by leaps and bounds and realized the crossover from the traditional basic research to serving the major national needs, which marks the increasing maturity of the discipline. The Beijing 2022 Olympic Winter Games is a major landmark event at an important historical time in China. The special need of using snow and ice as the sports interface has led China's cryosphere scientific team to focus on tackling key technical links of icy snow physics since 2016, and promoted the development of China's cryosphere scientific application research in the past five years. In view of the key technology of snow service for the Beijing 2022 Olympic Winter Games and the national needs of ice and snow economic development, a research team was formed by the State Key Laboratory of Cryospheric Science, in cooperation with scientific institutions (such as Beijing Normal University, Chinese Academy of Meteorological Sciences, and Harbin Sport University) and first-class enterprises in the domestic ice and snow industry (such as Yabuli Sports Training Base, National Alpine Skiing Centre, and Genting Snow Park). The team has solved many technical problems, including snow making, icy snow track making, snow quality prediction and snow storage. The team studied the impact of climate change on China's ski tourism and how ice and snow tourism can help with the sustainable development of mountainous regions economy. It also trained the first batch of graduate students and core technicians of ski resorts in China. This paper summarizes the key snow-making technology of the Beijing 2022 Olympic Winter Games, and projects the development path of China's ice and snow industry. It expounds the application and expansion of cryospheric science from the perspective of strategic thinking, knowledge building and practical innovation, and puts forward relevant thoughts and suggestions.
