When does the Big Snow solar term begin in 2020?

The date of the Heavy Snow in 2020 is Monday, December 7, 2020 (October 23rd of the Gengzi Year (Year of the Rat), 39 days away from the Heavy Snow in 2020). The Heavy Snow solar term in 2020 starts on December 7, 2020.
Heavy Snow is the 21st solar term in the 24 solar terms and the third solar term in winter. It snows heavily, the Big Dipper points to Gui, and the sun reaches 255 degrees of the ecliptic longitude. The solar term begins on December 6th and ends on December 8th of the Gregorian calendar every year.
Heavy Snow, like Light Snow, Rain Water, Grain Rain, Grain Full and other solar terms, are all solar terms that directly reflect precipitation.
The arrival of the heavy snow means that the weather will become colder and the precipitation will gradually increase. The most common events during the Big Snow solar term are a drop in temperature, rain or snow.

What are the weather characteristics of heavy snow?

Basic features: Cooling, rain or snow
During the Big Snow season, the most common occurrences are a drop in temperature, rain or snow. According to statistics, the month with the most severe cold air in my country is November in the lunar calendar. After the severe cold air passes, the average temperature in December in most parts of the north is about -20℃ to -5℃. Rain or frost will also occur in the south. Strong cold air often brings rainy or snowy days.
Heavy snow weather characteristics: heavy snow (blizzard)
Strong cold air can often cause snowfall over a large area or local blizzards, but the amount of snow is not the largest throughout the year. For example, in the middle and lower reaches of the Yellow River in northern my country and its surrounding areas, the heaviest snowfall occurs during the spring rain water solar term in late February. The reason is similar to the saying "Minor snow is heavier than Major snow", that is, late February has passed the coldest period of the year, and in the early spring weather, the warm air in the south begins to become active, and water vapor begins to become abundant, while the cold air in the north is still strong. In the confrontation between the two strong forces, the warm air flow rises strongly and persistently on the back of the denser cold air flow, which may lead to heavy snowfall. [2]
Heavy snow weather characteristics: freezing rain (rime)
When strong cold air reaches the south, especially Guizhou, Hunan, Hubei and other places, freezing rain is likely to occur. Freezing rain is snowflakes that fall from the high-altitude cold layer. Sometimes they melt into rain in the middle layer, and then in the low-altitude cold layer, they become supercooled water that is still raindrops even though its temperature is below 0℃. Supercooled water droplets fall from the air and when they reach the ground and hit any object on the ground, they immediately freeze and form freezing rain. When freezing rain occurs, an uneven layer of ice crust appears on the ground and objects, which will have a great impact on transportation, electricity, and communications, and will also cause damage to fruit trees. According to statistics in the book "Climate of the Middle and Lower Reaches of the Yangtze River", every December, when the temperature in the middle and lower reaches of the Yangtze River is between -3 and 0 degrees Celsius, freezing rain is prone to occur, and the probability of freezing rain occurring is 76%.
Heavy snow weather characteristics: rime
According to statistics, rime usually appears in the northwest, northeast and most of the Yangtze River basin from November every year to February of the following year, and is more common in mountainous areas with high humidity. Rime is the milky white ice crystal deposit on objects caused by direct condensation of water vapor in the air at low temperatures, or direct freezing of supercooled fog droplets. Places in my country with many days of rime in winter include Heilongjiang, Jilin, northern Xinjiang, and northern Shaanxi. Rime is a natural beauty that is widely appreciated by people, but it can sometimes become a natural disaster. In serious cases, it can break power lines and trees, affecting transportation, power supply, and communications.
Heavy snow weather characteristics: haze
In December, when winter has just begun in the south of the Yangtze River, when the temperature is relatively low in the morning, or after rain or snow, the humidity near the ground is high and large areas of fog may appear. Northern cities will also experience smog weather.
Characteristics of heavy snow weather: ice flood
In winter, the Baotou section of the river in Inner Mongolia is frozen, while the Lanzhou River in the south is not frozen. The river water flows to the frozen section. Because the ice and ridges on the frozen section block the river water from upstream, the water level is forced to rise, which easily causes flooding of the river embankment in the Baotou section. If the strong cold air comes late, it is easy to cause ice disasters in December.
