A large number of spherical ice accumulations are relatively rare in nature, and generally occur in shallows, lake banks and river banks. Due to the particularity of the morphological characteristics of spherical ice, it is often called ice balls or ice eggs. The formation and development of spherical ice are jointly controlled by meteorological, hydrodynamic and waterfront topographic conditions, and have certain spatial and temporal constraints. Multi-factor synergistic intervention in a short period of time is required to initiate ice balls to aggregate. Those rigorous conditions leads to the rarity of ice balls agglomeration, as well as the differences in the location, shape and number of ice balls pucks around the world. Up to now, there have been several reports on the ice balls phenomenon from Germany, Russia, Finland, Canada and other countries, whereas the frequency is very rare, about once every 20 to 30 years. In recent years, the ice egg phenomenon has also been discovered in Lake Chagan and Lake Sihai in Jilin Province, China, but the quantitative research on the formation of spherical ice from the formation to mass accumulation still lacks supporting measured data in situ. There is no doubt that the magical phenomena from nature provide more motivation and fun for scientific exploration and research.
