The causes of snowflakes:
Snowflakes grow from small ice crystals, and most ice molecules are hexagonal, so most snowflakes are hexagonal, and the shape of each snowflake is not exactly the same. The diversity of snowflake shapes is closely related to the water vapor conditions when it is formed. Hexagonal flake ice crystals have different saturated vapor pressures because of the different bending degrees of their surfaces, edges and corners, of which the saturated vapor pressure on the edges is the largest, followed by the edges and the plane is the smallest.
When the actual vapor pressure is the same, the growth of sublimation is different because of the different saturated vapor pressures on the surface, edge and corner of ice crystals. If the water vapor in the cloud is not very rich, the actual water vapor pressure is only greater than the saturated water vapor pressure on the plane, and the water vapor only condenses on the surface, then a columnar snowflake is formed; If the water vapor in the cloud is very rich, and the actual water vapor pressure is greater than the saturated water vapor pressure on the corner, then there is water vapor condensation on the surface, edge and corner, but the sharp corner is prominent, so many branches or star-shaped snowflakes are formed.
