Introduction of snow:

Snow is a natural phenomenon. Due to the difference of meteorological conditions and growth environment in the sky, all kinds of atmospheric solid precipitation are caused. The names of these atmospheric solid precipitation vary from place to place, from person to person, varied and extremely inconsistent.

For convenience, the International Ice and Snow Committee under the International Hydrological Association held a special international conference in 1949 on the basis of consulting experts from various countries, at which the proposal of "Concise Classification of Atmospheric Solid Precipitation" was adopted.

This concise classification divides atmospheric solid precipitation into ten types: snowflake, star snowflake, columnar snowflake, needle snowflake, multi-branch snowflake, axial snowflake, irregular snowflake, graupel, ice particle and hail.

The first seven kinds are collectively called snow. Why can't the last three be called snow? It turns out that there are two processes for water vapor to change from gas to solid. One is that water vapor first becomes water, and then water condenses into ice crystals. The other is that water vapor directly becomes ice crystals without water. This process is called condensation of water. Therefore, snow is solid precipitation formed by condensation of water vapor in the sky.
