Today and tomorrow (19-20 October), a strong cold air is continuing to move southward, and its impact is like a silent storm sweeping over most of the central and eastern regions.
In the face of the forces of nature, we are about to witness a major transformation of a series of weather phenomena.
The most important weather phenomenon brought by this cold air is the cooling of the wind, which is like a baton in the hands of nature's conductor, and with a wave, the temperature in the central and eastern parts will change drastically, and a new low after the beginning of autumn will be refreshed on a large scale.
In some areas, such as southern Hebei, southern Liaoning, and northern Shandong, this level of cold is very rare during the same period.
Imagine that when people are still immersed in the atmosphere that autumn has just begun, they are suddenly hit by such a cold air, and the feeling of falling from warm to cold is very strong.
People may have just been planning a weekend getaway to enjoy the autumn sun, but the arrival of cold air has forced everything to be replanned.
People on the streets may have been wearing light autumn clothes, but now they have to rummage through boxes and cabinets to find thick clothes to keep out the cold.
Second, the specific cooling details
The cooling brought by the cold air this time is considerable.
In Inner Mongolia, northern and eastern North China, Northeast China, Shandong and northern Jiangsu, the cooling range is between 6°C and 12°C, and even more than 14°C in some areas.
This cooling is like the needle on a thermometer being jerked down by an invisible hand.
The low point of the temperature is concentrated today and tomorrow, which means that the central and eastern parts of the country will experience a wide range of record low temperatures this weekend.
Cities such as Taiyuan, Beijing, and Tianjin, which are familiar and bustling cities, will also be significantly affected by the cooling.
In Beijing's hutongs, there may have been elderly people sitting at the door basking in the sun, but now they are afraid that they have to hide in the house and rely on the heating to keep warm; On the streets of Tianjin, those bustling commercial streets, people's clothing will quickly switch from fashionable autumn clothes to warm winter clothes; The citizens of Taiyuan will clearly feel the strong impact of the cold air when they go out in the morning, and they have to speed up their pace to reach their destination.
For city managers, it is also necessary to prepare in advance for cold weather, such as ensuring the proper operation of heating equipment.
3. Changes in minimum temperatures
As the cold air progresses, the minimum temperature changes significantly.
The minimum temperature of 10°C pushes south to the Huai River, which is like an invisible cold dividing line, dividing the central and eastern regions in two.
The area south of the Huai River, although it will be warmer than in the north, can also feel the aftermath of cold air.
The area north of the Huai River will enter a cold mode in an all-round way.
The minimum temperature of 0°C reached the northern part of Hebei, which means that parts of northern Hebei are already very close to freezing.
There, the early morning grass may be covered with a thin layer of frost and ice ballast may appear at the edge of the pond.
The minimum temperature in many places in eastern and northeastern Inner Mongolia has dropped below minus 5 °C, and these places are like being enchanted by the cold ice queen, entering a world of ice and snow.
In the rural areas of the Northeast, people are busy keeping their livestock warm and their houses against the cold. Herders in eastern Mongolia should pay more attention to the living environment of cattle and sheep to prevent them from getting sick due to the cold.
Fourth, the new cold air forecast
Just as we were still dealing with this strong cold air, the meteorological department issued a new warning.
From the 20th to the 22nd, new cold air is about to affect the continent from west to east.
It's like a relay race of cold air, where the previous cold air has not completely subsided, and new cold air is coming one after another.
For the public, this is news that cannot be taken seriously.
Under the influence of such continuous cold air, we must pay more attention to the changes in the weather and take measures to protect against the cold and keep warm.
Especially those who need to work outdoors, such as construction workers, couriers, and sanitation workers, should be prepared in advance and wear warm enough clothes to avoid getting sick in cold weather.
For ordinary citizens, the elderly and children at home are the objects that need to be taken care of, and it is necessary to ensure that they live in a warm and comfortable environment.
5. A new round of precipitation in the central and eastern regions
From today to the 21st, the central and eastern regions will usher in a new round of precipitation.
Heavier precipitation is concentrated in the Sichuan Basin, where people may be accompanied by rain for some time.
The Sichuan Basin already has a humid climate, and this precipitation may make the air more humid and bring some inconveniences to people's lives, such as the difficulty of drying clothes and the easy accumulation of water on the roads.
In Inner Mongolia, northern China and other places, there may also be snowfall.
The scene of snowflakes falling is beautiful, but it also presents some challenges.
For the traffic department, it is necessary to take anti-skid measures on the road in advance to ensure the safety of vehicles and pedestrians; For citizens, they should be more careful when traveling, especially when walking or driving on the road after snow, and pay attention to traffic safety.
Under such weather changes, the entire central and eastern regions are like a huge stage, with weather phenomena such as cold air, precipitation, and snowfall being the protagonists on the stage, which are intertwined with each other and jointly perform a great drama of autumn and winter.
As spectators and participants living on this land, we must actively respond to these weather changes and be fully prepared to protect the health and safety of ourselves and our families in the face of the forces of nature.
From an agricultural point of view, such weather changes also have important implications.
For winter wheat in the north, proper precipitation and cooling can help the growth of wheat seedlings, but if the snowfall is too heavy, the wheat seedlings may be crushed, and farmers need to check and deal with them in time.
In the south, precipitation may affect the drying of some autumn crops, and farmers need to find ways to ensure that the crops are returned to the warehouse.
From a tourism point of view, such a change in weather is a different experience for tourists.
The snow in the north attracts many tourists, and famous attractions such as Harbin's Ice and Snow World may welcome even more tourists.
However, tourists also need to pay attention to warmth and safety when traveling, so as to prevent accidents due to weather conditions during the trip.
In such weather conditions, all aspects of society as a whole need to actively adjust and respond.
Meteorological departments should do a better job of more accurate forecasts to provide the public with timely and accurate weather information; The power sector should ensure a stable supply of electricity so that people can heat their homes normally in cold weather; Medical departments need to be prepared for diseases that can be triggered by cold weather, such as colds and respiratory diseases.
In conclusion, this series of weather changes is a signal from nature that reminds us that the seasons are changing and that we need to adapt to this change and live in harmony with nature.
Whether it is the life of an individual or the operation of the whole society, we must make corresponding adjustments in this weather background in order to better meet the upcoming winter.
