Will it snow in the great cold in 2023? Are there any legends among the people?

Snow in the cold is a good sign. In the folk, it is a taboo not to snow in the cold weather. There is a saying that "it is good to have a good year in the cold day", which means that it is auspicious to snow in the cold weather, which makes sense from the perspective of natural science. Universities can kill locusts in winter, and there will be no insect disaster in the next year. Moreover, snow in winter can provide water for crops and save energy for spring, so it is perfect to snow in cold weather.

Great cold refers to extremely cold weather. During the severe cold solar term, the atmospheric circulation is relatively stable, and the adjustment period of circulation is about 20 days. When this circulation is adjusted, there will often be a wide range of rain and snow weather and strong winds to cool down. When the west of 80 degrees east longitude is a long wave ridge and East Asia is a coastal trough, under the influence of northwest wind flow control and constantly supplemented cold air, China will have a sustained low temperature.

Like slight cold, great cold is also a solar term indicating the degree of cold weather. Modern meteorological observation records show that in some areas of China, severe cold is not as good as slight cold, but in some years and a few coastal areas, the annual minimum temperature will still appear within the severe cold solar terms. Therefore, it is necessary to continue to do a good job in the cold protection of crops, especially to protect livestock from wintering.

In the severe cold season, the average temperature in most parts of southern China is 6℃ to 8℃, which is nearly 65438 0℃ higher than slight cold. The proverb "slight cold and cold, cold into a ball" shows that the great cold solar terms are also the cold period of the year. Slight cold and severe cold are the periods with the least rainfall in a year.

Cold agriculture

In the severe cold season, it is necessary to master the law of changes in the temperature of agricultural production, pay close attention to the forecast of meteorological departments at any time according to different years, different geographical locations and topographic conditions, and plant crops reasonably to avoid unnecessary losses. Especially in the large-scale introduction of cash crops, it can not be ignored; Small-scale planting should also pay attention to the surrounding terrain and environment. For example, around large reservoirs, due to the temperature regulation of water, freezing damage is often light or not. Some cash crops and flowers that are easily frozen can be planted around the reservoir before the cold winter comes. According to the weather changes, the temperature and humidity of greenhouse crops should be well controlled. Both ends of the greenhouse should be ventilated around noon, but they must be closed before 4 pm to maintain the temperature in the greenhouse.

During the cold solar term, the weather is cold and the humidity is low, and the plants have stopped growing and are relatively dry. It is necessary to pay special attention to the safety of using fire in the wild or heating at home, and beware of fire.
