In what month does it snow in Beijing?

It may snow in Beijing from 1 1 to 1 every year, depending on the year, or it may not snow until 1 in some years. But the snow in Beijing has basically melted to the ground. If we only look at the snow, we will know whether there is snow in the weather.

Beijing's climate is a typical semi-humid continental monsoon climate in the north temperate zone, with high temperature and rainy summer, cold and dry winter and short spring and autumn. The frost-free period of the whole year is 180 ~ 200 days, which is shorter in the western mountainous area.

In 2007, the average rainfall was 483.9 mm, which is one of the most rainy areas in North China. The seasonal distribution of precipitation is very uneven. 80% of the annual precipitation is concentrated in June, July and August in summer, and there are heavy rains in July and August.

Formation conditions of snowfall

Water vapor in the atmosphere condenses directly or water droplets condense directly, which is snow. It can also be said that it snows when the temperature in the cloud is too low and small water droplets form ice crystals and fall to the ground or snow. Ice absorbs heat when it melts, so the ground temperature will be lower than when it snows.

1. The atmosphere needs to contain cold ice crystal nuclei.

2. Sufficient water vapor. Below 3.0℃ (freezing point). If the cold air is quite strong and carries moisture, it can snow at the temperature of 1℃ to 10℃.

Where it can snow: The climate zone belongs to the middle latitude to the high latitude (that is, the area south of the Tropic of Cancer/north of the Tropic of Cancer), and some mountainous areas or plateaus with terrain above 2000 meters above sea level in low latitudes will also have the same opportunity.
