"When the weather is cold, water vapor will condense when it meets tiny particles. These small particles are called ice crystals, which fall slowly. In this process, more water will condense on them, and they will slowly grow branchlets, thus becoming the snowflakes we see.

Snow is beneficial to the growth and development of crops. Snow is a kind of material with good thermal insulation effect, which can protect plants from frostbite in cold winter, and the melting of snow water in the next spring can provide a good water source for vegetation.

"Because of the low temperature in winter, the ground temperature is below zero, and the temperature of high-altitude clouds is even lower. Water vapor in the cloud condenses directly into small ice crystals and snowflakes. When these snowflakes increase to a certain extent, the airflow can't hold, and falling from the clouds to the ground means snow.
