Is it good or bad to snow in spring?

It is beneficial to snow in spring. Snow in spring is a good year, which will kill pests and diseases. Snow means that the temperature is only a little lower when it rains. Chun Xue is as expensive as oil. Because the growth and development of everything in spring is in urgent need of water, bamboo must have a lot of water in spring, so the spring rain in Chun Xue is oil, and the growth and development of everything is a natural law.

There are conditions for snowfall.

One condition is that water vapor is saturated. Another condition is that there must be condensation nuclei in the air.

The size of snowflake crystals is closely related to the temperature at which water vapor condenses and crystallizes. The colder the weather, the lower the temperature and the smaller the snowflake crystal. When the weather is very cold, the diameter of snowflake crystals formed is often less than 0.05 mm.

Meteorologists have observed that prismatic ice crystals will form when the temperature is between -8℃ and -5℃. When the temperature is -5℃ to -3℃, needle-like ice crystals are formed; When the temperature is -3℃ to 0℃, thin hexagonal plate-like ice crystals are formed. It can be seen that when the temperature is -3℃ to 0℃, the shape of snowflake is the largest and most complete.

Snowflake crystals formed in very cold weather are so small that they are almost invisible to the naked eye. Only when they shine in the sun can people find them as fine powder. This kind of snow is called dry snow.
