The Central Meteorological Observatory issued the highest-level warning for the cold wave orange alert
Cooling “cliff style”, cold wave of “overlord”
It is estimated that more than 80% of the country may be “frozen” by 31
What kind of cold will we face?
Cold weather across the country
Energy demand is growing faster than expected
How to ensure that people live warmly during winter?
Today (29), the range of strong winds expanded rapidly to the south. The Central Meteorological Observatory issued an orange cold wave warning for the second day in a row. As the cold snap moves south, the lowest temperature freezing line of 0 ℃ will push south. How long will this cold snap last? How is the situation everywhere?

Why did the cold snap come so quickly and urgently this year?
He Lifu, chief forecaster of the Central Meteorological Observatory:Since the middle of November this year, the cold air has been more active and its intensity has become stronger and stronger. Between them, two strong cold winds appeared in mid or late November and December, affecting most of our country, so that as of November of this year, most areas of our country continued to be colder than usual. normal. Therefore, the reason why the cold snap broke out earlier this year may be due to the fact that the accumulated winds in the middle and high latitudes continue to push south towards East Asia this year, resulting in a frequent and active cold air.
What are the characteristics of this year’s “Overlord” cold snap compared to the 2016 cold snap?
He Lifu, chief forecaster of the Central Meteorological Observatory:These two cold waves, in terms of intensity and rate of cooling, the real forces are basically the same, but this cold wave still has some characteristics of its own compared to the strong cold wave of 2016.
It showed up early. 2016 appeared from January 21 to 25, which was the cold winter of January 49 and 9. This time it was 20 days earlier, at the end of December.
This round of cold waves was relatively short-lived. The last time lasted five days. This time it lasted about three days and less than four. However, this time the strong wind covers a wide area and the wind is strong. There will be five to five days in most of the north and south. Grade 6 gusts, so this round of cold wave wind chill effect is more obvious. Also, this outbreak of cold air was a single outbreak, just like a container of cold water was poured quickly, while the cold wave in 2016 was divided into two or three waves, a container of water was poured two or three times , and the duration was different.
This round of cold wave rain and snow intensity is not as good as 2016. In 2016, most of the southern Yangtze River experienced large-scale heavy snowfall and freezing weather. In this round of cold waves, the snowfall was very short and the amount of snow was very short. It was also very weak, except for some places in Shandong, Jiangsu and Anhui provinces, which were slightly larger, the others were very weak and stopped early.
The next three months do not rule out the possibility of another cold wave
He Lifu, chief forecaster of the Central Meteorological Observatory:Judging from this winter, there are still three months to go. January, February, and even March are a relatively frequent period of cold snap activity, and this year’s cold snap weather occurred in the context of La Niña. Generally, in the context of La Niña, the probability of a colder state in winter is greater, so the possibility of another cold wave in the next three months cannot be ruled out.
What kind of protection should be done when the cold snap is approaching?
He Lifu, chief forecaster of the Central Meteorological Observatory:First of all, you have to pay attention to personal protection, because the temperature drop is extremely severe, and many cold spells bring the coldest weather this year, and sometimes even break the extreme historical value. Therefore, people should take good care of cold and heat and prevent cardiovascular and cerebrovascular diseases This year is a special epidemic situation, and special personal protection should be taken. Also, this cold snap was extremely windy and lasted almost 48 hours, the gusts were even level 7 or higher, so outdoor activities and outdoor work should be minimized, and risks should also be prevented. of fires in forests and grasslands.
What should I watch out for in traffic during cold waves?
He Lifu, chief forecaster of the Central Meteorological Observatory:Due to the relatively small range of snow, rain and snow in this round of cold wave weather, it is mainly in the area south of Huanghuai, and the duration on the ground is short, the amount of snow is relatively small, and the snow on the ground is not obvious. Although the rain and snow are very small, the road can freeze quickly due to the relatively large temperature drop, which requires prevention.
What about energy reserves? Can you survive the winter without problems? No problem of natural gas supply
Wang Zhongying, Director of the Energy Research Institute of the National Development and Reform Commission:Judging from the current situation of national supply and demand, although there may be greater pressure to guarantee supply in some regions and certain periods of time, the general balance is that gas and electricity as a way of life for people are guaranteed. Specifically, like natural gas, the current natural gas inventory can be guaranteed for about 70 days. At the same time, the National Development and Reform Commission has also taken other measures to increase the management of the national gas pipeline network to a historical level through measures such as increasing gas storage in gas storage, and also organized the increased “gas from the south to the north” to ensure that LNG vessels are received and unloaded on time at ports. In terms of prices, international and domestic LNG prices have shown a downward trend, and are expected to fluctuate and decline in the subsequent period, so there is no supply problem.
Power supply is tight in some areas this winter
Wang Zhongying, Director of the Energy Research Institute of the National Development and Reform Commission:This year, there has been a shortage of supply in some local areas, which is a lack of expectations for the first cold weather. The other is that after the epidemic, the national economy recovered, the international epidemic broke out again, a large amount of demand in the international market turned to the domestic market, and China’s energy production and consumption have also been increased considerably. Therefore, there may be some pre-plans that were not in place before. But personally I believe that to really solve this problem, we must rely on the market to solve it. For example, the natural gas market, the oil and gas market and the electricity market can be completely solved, because we have no problems in terms of production capacity, technology transmission and network transmission capacity. In fact, in the report of the Fifth Plenary Session of the Communist Party of China Central Committee, the recommendations on the outline of the “XIV Five-Year Plan” propose to follow five principles, of which the fifth principle is to adhere to the concept of system. That is why I personally think about how to establish a national market and solve it through the market. In the next step of the work, energy, especially electricity supply, how to break the barrier of interest between companies, break the barrier of interest between provinces, and put ourselves When the transmission potential of China’s power grid is discovered, energy from the west can be transmitted to the east and the center.
What about energy reserves? Can you survive the winter without problems? Guaranteed supply of coal and electricity
Wang Zhongying, Director of the Energy Research Institute of the National Development and Reform Commission:Judging from the current situation of national supply and demand, although there may be greater pressure to guarantee supply in some regions and certain periods of time, the general balance is that gas and electricity as a way of life for people are guaranteed. Specifically, like natural gas, the current natural gas inventory can be guaranteed for about 70 days. At the same time, the National Development and Reform Commission has also taken other measures to increase the management of the national gas pipeline network to a historical level through measures such as increasing gas storage in gas storage, and also organized the increased “gas from the south to the north” to ensure that LNG vessels are received and unloaded on time at ports.
