Will it snow in Xuzhou in winter?
Xuzhou has a temperate monsoon climate with four distinct seasons, no heat in summer and no cold in winter. Annual temperature 14℃, annual sunshine hours 2284-2495 hours, sunshine rate 52%-57%, annual frost-free period 200-220 days, annual precipitation 800-930 mm, and rainy season precipitation accounts for 56% of the whole year.
The climate is characterized by four distinct seasons, abundant sunshine, moderate rainfall and both rain and heat. Among the four seasons, spring and autumn are short, winter and summer are long, the weather in spring is changeable, summer is hot and rainy, autumn is crisp, and cold waves frequently strike in winter.

Reasons for the formation of snowflakes:
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 there is a little more water vapor, the actual water vapor pressure is greater than the saturated water vapor pressure at the edge, and the water vapor will condense at the edge and surface. Because the speed of condensation is also related to the degree of bending, the place with a large degree of bending will condense faster, so the speed of condensation at the edge of ice crystals is faster than that on the surface, and more flake snowflakes will be formed at this time.
If the water vapor in the cloud is rich, the actual water vapor pressure is greater than the saturated water vapor pressure on the corner, so there is water vapor condensation on the surface, edge and corner, but the sharp corner is prominent, the water vapor supply is the most sufficient, and the condensation grows fastest, so many branches or star-shaped snowflakes are formed, so it is also called Liuchu.
Coupled with the constant movement of ice crystals, their temperature and humidity conditions are constantly changing, which makes the growth rates of various parts of ice crystals inconsistent and forms various snowflakes.
