The cold wave and cold air, like a cold current, swept in, and the central and eastern regions of the mainland are ushering in a new round of severe cold tests. In the past few days, heavy wind, rain and snow have raged in this vast land, the temperature has plummeted, and the chill has gradually spread. According to the weather forecast, in the next three days, this cold wave will strengthen again, and the vast areas in the central and eastern parts will fall into severe cold again. The northern part of the Shandong Peninsula is likely to receive moderate to heavy snowfall, while local areas are more likely to experience heavy snowfall or heavy snowfall, while Guizhou, Hunan and other places may also be hit by freezing rain.
In this ice and snow attack, residents in the central and eastern regions will face more severe cold weather, and their lives and production will be affected to a certain extent.
It is expected that in the next three days, the vast areas in the central and eastern regions will be affected by a new round of strong cold air again, the weather will be bad, and the local area will usher in moderate to heavy snow, and even the possibility of blizzard or heavy snow, at the same time, Guizhou, Hunan and other places may also encounter freezing rain.
[The area affected by the cold wave spreads, and the cooling range is amazing]
Some areas in North China, central and western Inner Mongolia, Huanghuai, eastern Northwest China, Jianghuai, central and eastern Jiangnan, and eastern South China will face a cooling of 4~8 °C, of which the maximum local cooling range in eastern Liaoning, eastern Jilin, central and northern Shanxi, and central and western Inner Mongolia will even exceed 10 °C.
This astonishing drop in temperature will have a certain impact on the daily life of local residents and agricultural production, and it is necessary to do a good job of cold protection and farmland management in advance.
[Windy weather is coming with a cold wave, and the wind strengthens to take precautions]
The cold wave is not only cooling, but also windy. North China, central and western Inner Mongolia, Huanghuai, eastern Northwest China, Jianghuai, central and eastern Jiangnan, eastern South China and other places will usher in local areas of 4 to 6 strong winds, and some areas may even exceed 7 gusts. Such windy weather requires residents to take precautions, especially when working outdoors and when traveling.
Among the 24 solar terms of the lunar calendar, this period coincides with the "heavy snow" solar term. The ancients said: "In the heavy snow season, the cold is kept out, and the carpenter cooks wine to warm the cold officials." This illustrates the need for people to be more attentive to the cold during the snowy season, and carpentry to cook wine to keep out the cold, which is both a wisdom of life and a reflection of the ingenious ways in which different professions deal with cold weather.
There is a saying in the agricultural proverb: "Heavy snow covers the fields, and spring plowing is beneficial." "This means that heavy snow can cover the fields with a thick layer of thermal covering, which helps to keep the soil warm and moist, creating good conditions for next year's spring planting. This reflects the good use of the natural climate in the farming culture, as well as the intelligent use of agricultural production.
The formation and propagation of cold air during cold waves is an important area of research in meteorology. Such large-scale changes in the climate system involve many factors such as high and low pressure systems in the atmosphere, temperature gradients, and so on. By understanding this scientific knowledge, people can better understand the laws of weather changes, prepare in advance, and mitigate the impact of cold waves on life, agriculture, etc.
Under the attack of the cold wave, residents need to strengthen their warmth and cold protection, especially the elderly, children and other groups that are vulnerable to cold. Carrying rain gear and cold-proof items when going out, maintaining sufficient physical strength and adequate clothing is an effective means to reduce the impact of the cold wave. Pay attention to safety when traveling, avoid traffic accidents caused by windy weather, and ensure the safety of people and property.
The arrival of cold air makes winter even colder, and it also makes people have a deeper understanding of the changes in the weather. In this process, strengthening the Xi of meteorological knowledge and better understanding of the laws of weather will help improve our ability to cope with climate change. May everyone be warm and healthy this winter and have a livable season.
