The Origin of Snow
Snow is a natural phenomenon. Due to the differences in meteorological conditions and growth environments in the sky, various Atmospheric solid precipitation. The names of these atmospheric solid precipitations vary from place to place and from person to person. They have many names and are extremely inconsistent. For the sake of convenience, the International Snow and Ice Commission of the International Hydrological Association convened a specialized international conference in 1949, at which a proposal for a concise classification of atmospheric solid precipitation was adopted.
This concise classification divides atmospheric solid precipitation into ten types: snow flakes, star-shaped snowflakes, columnar snow crystals, needle-shaped snow crystals, multi-branched snow crystals, axis-shaped snow crystals, and irregular snow crystals. , graupel, ice particles and hail.
The first seven are collectively called snow. Why can’t the last three be called snow? It turns out that there are two processes for turning gaseous water vapor into solid water. One is that water vapor first turns into water, and then water turns into water again. Condensation into ice crystals. There is also a method where water vapor directly turns into ice crystals without passing through water. This process is called sublimation of water, so snow is solid precipitation that comes from the sublimation of water vapor in the sky.
