Will it snow heavily this year?

As of January 6, 2023, whether there will be heavy snow this year depends on the actual situation.

The temperatures vary from province to city, so there is no exact answer when it comes to snow. Northern areas that have seen heavy snowfall in winter in previous years will also see heavy snowfall this year. Moreover, due to the emergence of the La Ni?a phenomenon, severe weather with heavy snowfall is prone to occur, but the current probability is about 60%. If there are no other climate factors, The snow level is about the same as in previous years.

But if you are in the south, there will not be much snow, especially in Guangdong, Hainan and other places, where there may be no snow all year round and the temperature will tend to be warm.

Causes of snow formation:

Snow is a natural phenomenon. Due to differences in meteorological conditions and growth environments in the sky, various atmospheric solid precipitations are caused. The names of these atmospheric solid precipitations vary from place to place and from person to person. The names are numerous and extremely inconsistent.

For the sake of convenience, the International Snow and Ice Committee of the International Hydrological Association convened a specialized international conference in 1949 on the basis of soliciting opinions from experts from various countries. At the meeting, the regulations on atmospheric solid precipitation were adopted. Proposal for a concise classification.

This concise classification divides atmospheric solid precipitation into ten types: snow flakes, star-shaped snowflakes, columnar snow crystals, needle-shaped snow crystals, dendritic snow crystals, axis-shaped snow crystals, and irregular snow crystals. , graupel, ice particles and hail. The first seven are collectively called snow.

The latter three cannot be called snow because there are two processes from gaseous water vapor to solid water. One is that water vapor first turns into water, and then the water condenses into ice crystals; the other is water vapor. Without passing through water, it directly turns into ice crystals. This process is called water sublimation. Therefore, snow is solid precipitation formed by the condensation of water vapor in the sky.
