From now on, strong cold air hits many places to cool down by 12℃ to 14℃
The scope of influence is basically similar to the cold wave weather process at the beginning of this month; the minimum temperature in the Beijing Plain has dropped to about -3℃ to -6℃
From today to next Monday, a strong cold air will affect most parts of our country. The scope of the impact is basically similar to that of the cold wave at the beginning of this month, but the cooling rate, wind force, and rain and snow intensity are significantly weaker than last time.
Affected by this, the temperature in western Inner Mongolia, western Shanxi, eastern Huanghuai, central and eastern Jianghuai, northern Jiangnan and southwestern China will drop by 12°C-14°C.
According to the latest analysis of meteorological data, there will be a strong cold air affecting Beijing from the 21st to the 22nd, which will bring strong winds and strong cooling weather.
Affected by cold air, diffusion conditions and visibility at night improved.
The cold air has a wide range of influence and low minimum temperature
According to the latest forecast from the Central Meteorological Observatory, from November 19 to 22, a strong cold air will affect most of my country from west to east.
Overall, the cold air process has a wide range of influence, low minimum temperature, and strong wind on land and sea. The range of influence is basically similar to the cold wave weather process at the beginning of this month. The minimum temperature of 0℃ will be pressed south to the middle and lower reaches of the Yangtze River.
Specifically, it is expected that on November 19, the cold air will mainly affect the northern part of Xinjiang; on the 20th, the cold air will advance eastward, and strong winds will appear in the central and eastern parts of the northwestern region and the western part of Inner Mongolia; Most of the eastern region.
Affected by this, the temperature in parts of the northwest and central and eastern regions will drop by 6℃-10℃. Among them, the temperature will drop by 12℃-14℃ in western Inner Mongolia, western Shanxi, eastern Huanghuai, middle eastern Jianghuai, northern Jiangnan and southwestern China.
Most of the above areas are accompanied by northerly winds of magnitude 4-6, and gusts of magnitude 7-9 in central and western Inner Mongolia, northern North China, and eastern Northeast China.
There will be strong winds of magnitude 7-9 and gusts of magnitude 10 in the eastern and southern waters of my country.
After the temperature drop, on the morning of the 23rd, the 0℃ line of the lowest temperature will press south from the middle and lower reaches of the Yangtze River to the northern part of the Sichuan Basin; the 10℃ line is located in the southern part of South China.
The lowest temperature in the Beijing Plain can drop from -3°C to -6°C.
The impact of rain and snow is mainly concentrated in Xinjiang and Northeast China
The impact of rain and snow in this cold air process is mainly concentrated in Xinjiang and Northeast China. There will be light to moderate snow or sleet in northern Xinjiang, eastern Inner Mongolia and Northeast China, and heavy snow in northern Xinjiang, Heilongjiang and eastern Jilin; cumulative snowfall 5-20 mm, about 30 mm in the northeastern part of Heilongjiang.
There was light to moderate rain in Huanghuai and most of its south.
Experts remind that the public in coal-fired heating areas should pay attention to the safety of using fire for heating and prevent carbon monoxide poisoning.
At the same time, strong wind cooling is unfavorable to epidemic prevention and control, urban operation, and agriculture and animal husbandry. It is necessary to make wind-proof reinforcement for large sheds, livestock pens and temporary structures in advance, and strengthen the prevention of respiratory diseases and health and epidemic prevention.
Xinjiang, Inner Mongolia, and Northeast China need to pay attention to the adverse impacts on traffic caused by wet and slippery roads, snow and icing caused by rain and snow, and pay attention to traffic safety.
■ Interpretation
"Refrigeration" effect may be stronger than last time
Hu Xiao, chief meteorological analyst of China Weather Network, introduced that the two cold waves have similar "weather configuration", so this cold air will continue the basic characteristics of the cold wave in early November-wide range of influence, strong cooling power, and comparison of rain and snow. Wide, descending from the northwest, the southward range is very wide, including southern China will also be affected.
The difference between the two cold air is that the strength of this cold air is not as strong as the cold air in early November, that is to say, in terms of the degree of cooling, it is not as fierce as the last cold air process.
However, the cooling effect of this cold air may be stronger than last time.
Due to the weak cold air in the past two days, it will cause a general temperature drop above 4°C.
Therefore, when this strong cold air comes, the temperature will continue to fall.
In Northeast China, the temperature will be lower than that in the first ten days of November, and the body feels colder. Another example is South China. At the beginning of next week, the coldness brought by the cold air southward will even exceed the impact of the cold wave in early November. The highest temperature in Guangzhou is only around 15-16℃.
