2. Interpretation: Snowflake, a kind of crystal, whose structure changes with the change of temperature, also known as Weiyanghua and Liuchu, is a beautiful crystal, which sticks together to form snowflake during falling.
3. Synonyms: ice and snow.
4. Snowflake formation: One condition is water vapor saturation. The maximum amount of water vapor that air can hold at a certain temperature is called saturated water vapor. The temperature at which air reaches saturation is called dew point. When saturated air is cooled to a temperature below the dew point, the excess water vapor in the air becomes water droplets or ice crystals. Because the saturated water vapor content of ice surface is lower than that of water surface, the water vapor saturation required for the growth of ice crystals is lower than that of water droplets.
