Original title: Heavy snowstorms occurred in many places in Northeast China and Inner Mongolia. Experts: Snow disasters may be triggered

The rapid development of multiple weather systems

The intense confluence of cold and warm air causes

Due to the current cold wave, from November 7th to 8th, heavy snowstorms or extreme snowstorms occurred in parts of southeastern Inner Mongolia, central Liaoning, and western Jilin. By the night of the 8th, the thickness of newly added snow in Inner Mongolia and Northeast China reached 10 cm to 20 cm, and the local area could reach more than 40 cm.

According to the China Meteorological Administration, as of 5 o’clock on the 9th, the maximum snow depth in Shuangliao, Jilin was 45 cm; at 8 o’clock on the 9th, the maximum snow depth was 53 cm in Tiedong District, Anshan, Liaoning.

The Liaoning Provincial Meteorological Bureau has issued a red warning for blizzards. From the night of the 7th, Shenyang has ushered in the rare weather of “freezing rain + blizzard”. The Meteorological Observatory of Inner Mongolia Autonomous Region issued a blizzard red warning signal at 10:50 on the 8th, and a severe blizzard occurred in Tongliao Bureau.

Zhou Chunxiao, chief forecaster of the Liaoning Provincial Meteorological Observatory, introduced that in the Northeast and Inner Mongolia during the current cold wave, the amount of snowfall and the thickness of the snow were so deep, which was caused by the rapid development of multiple weather systems and the intense convergence of cold and warm air.

“On the one hand, there is strong dynamic uplift and water vapor convergence; on the other hand, the system moves slowly and the snowfall lasts for a long time, so there is obvious rain, snow, and cooling process.” Zhou Chunxiao explained that at 500hPa high altitude, the northeast cold vortex developed strongly. , The low trough moved eastward and northward, leading to the explosive development of surface cyclones, forming a deep low pressure system from low level to high altitude, and the conditions for dynamic uplift were strong; at the same time, the southwest airflow transported sufficient warm and humid air to the northeast region, and the water vapor was abnormally strong.

It is understood that this cold wave in Northeast China has a large amount of precipitation and a long period of precipitation. Due to the multiple changes in temperature stratification, the phase of precipitation is very complicated and will undergo many changes, including rain, sleet, snow and even freezing rain.

Rural bungalows are almost covered by snow

Many local residents in Inner Mongolia told China News Weekly that the snowfall has not stopped since November 6.

On November 8, Wang Yuehong, a citizen of Tongliao, Inner Mongolia Autonomous Region, introduced that local municipal vehicles have been clearing snow all day since the snow fell on the 6th, but they can only guarantee the normal traffic of the city’s main roads. Because of the thick snow, the cars driving out of the community can’t get in, and the cars inside can’t get out. The road area in the community has snow covered their knees. At the same time, there are windy weather. Residents have tried to minimize going out.

“The local government attaches great importance to the residents, but the snow is too big to be clear.” Wang Yuehong said, after the snowfall, the local notice temporarily notified students to suspend school for 3 days, but the work has not been suspended yet because vehicles are not available. Normal traffic, high winds and blizzards make it difficult for residents to go out.

“The last time I have such a heavy snow should be more than 20 years ago.” Han Shiyong, a citizen of Chifeng City, Inner Mongolia Autonomous Region, also said that since the 6th, the local traffic management department has been clearing the road surface all night to ensure that the main roads of the city can pass normally. Vehicles on the small roads outside the road are no longer passable.

Han Shiyong told China News Weekly that the extreme blizzard has affected the normal production and life of local people. The snowfall and snow accumulation are serious. The local people have given up traveling by car for safety reasons, and there are very few vehicles on the road. But because work has not yet stopped, Han Shiyong walked for about an hour on the 4-kilometer road to work. “Now, he basically goes to work on foot, and only four-wheel drive can walk on the road.”

Han Shiyong introduced that on the 8th, he returned from the urban area to his hometown in the countryside. He drove a distance of 90 kilometers for a total of 3 hours. There were many vehicles stuck in the snow and road ditch on the side of the road. The snow in my hometown has reached more than 30 centimeters, and the sheep pen at my home has been crushed. It is necessary to “dig sheep” out of the snow, and some sheep have died.

Long-term snowfall will bring more uncertainty.

According to reports from Beijing time, on November 8, the roof of a building of No. 53 Middle School in Shenyang City, Liaoning Province collapsed. In the video, a large number of windows on the top floor of the building were destroyed, and curtains flew out. The staff of the local education bureau responded that the roof was damaged due to excessive snow accumulation, and no one was injured because the school was closed at the time of the incident.

Several interviewees told China News Weekly that compared with urban areas, the situation in rural areas is more serious. Over the past few days, the collapse of cowsheds and sheepfolds caused by snow accumulation has brought direct economic losses to the local people.

According to Fei Fei (pseudonym) of Dongyikeshu Village, Qianjiadian Town, Tongliao City, Inner Mongolia, the blizzard started on the 6th and caused a large amount of snow to accumulate on the sunny slopes where residents live. The depth of snow has reached 60. ~70 cm, the houses of the villagers have been buried.

“The doors have been closed for the past two days, and the snow (Xiaoxue) started to turn last night. Everyone in our family dug a road from the door.” Ju Fei said that the wind was about 8 or 9 in the previous two days, and people were outside. The color steel sheds that were renovated by the old houses of the villagers were crushed, the cattle sheds and sheep pens were crushed, and the economic losses could not be counted. keep.”

According to Ju Fei, because the snow situation has just improved and the snow is too deep, the villagers basically rely on “crawling” to travel. The local forklifts have been cleaning the main streets overnight to ensure that the roads with the outside world remain unblocked.

“It may cause a snow disaster”

In terms of snowfall or snow depth, is this process extreme? Zhou Chunxiao said that affected by the northeast cold vortex and the strong cold air in Siberia, the current snowfall in western Liaoning has exceeded the historical extreme value since the meteorological record in 1951, and the snowfall in parts of the central and northern parts of the central and northern regions continues, and there are also historical extremes. Possible.

According to the China Meteorological Administration, as of 5 o’clock on the 9th, the maximum snow depth in Shuangliao, Jilin was 45 cm; at 8 o’clock on the 9th, the maximum snow depth was 53 cm in Tiedong District, Anshan, Liaoning.

Zhang Guilian, chief forecaster of the Meteorological Observatory of the Inner Mongolia Autonomous Region, introduced that the snowfall range was relatively large this time, with extreme blizzards in the southeast of Chifeng City and the south of Tongliao City. The maximum snowfall occurred in Kulun Banner, Tongliao City, reaching 60 mm, and the local snow depth reached 50 cm.

Zhang Guilian added that from the night of the 5th to the 7th, extreme snowfall events occurred at 32 stations in Inner Mongolia, of which the snowfall at 3 stations broke through the historical extremes, namely Ximeng Xiwu Banner, Tongliao City Naiman Banner Qinglong Mountain and Kulun Banner. .

Zhang Guilian analyzed that the rain, snow, strong winds, and cooling weather were mainly due to the high-altitude trough where the cold air moved eastward in Xinjiang, slowly gradually strengthening into a cold vortex during the eastward movement. Because the cold vortex moves slowly, it is easy to cause long-term and large-scale snowfall.

In addition, the thickness of snow cover is also related to air temperature and moisture content of snowflakes. For example, the thickness of snow per unit of precipitation will change significantly with temperature. When the temperature reaches the range of -6℃ to -8℃, the depth of snow per unit of snowfall will reach the maximum; as the temperature rises, the unit of snowfall The amount of snow depth will be significantly reduced.

“During this snowfall, the water vapor conditions were good and the temperature was suitable, so the thickness of the snow was deeper.” Zhang Guilian said.

Regarding whether the cold wave will cause a snow disaster, Zhang Guilian believes that the snowfall during this cold wave is relatively large, and the thickness of snow in the southern part of Tongliao City, the southern part of Chifeng City, and the south-central-eastern part of the southwest of Xilin Gol League is more than 15 cm. Facility agriculture will be affected. Influence of low temperature and chilling injury. If the later snow cannot melt as quickly as possible, severe “winter snow” will be formed, which will be a severe test for feed reserves in pastoral and semi-agricultural and semi-pastoral areas, and may cause snow disasters.

In addition, she introduced that the blizzard and drastic cooling accompanying the strong cold wave pose a serious threat to livestock. A drastic drop in temperature is most likely to cause colds, tracheitis and other diseases in livestock, and it is easy to cause “sheep on the stack” (when it is cold). The phenomenon of sheep pressing each other in a pile), leading to miscarriage of the female animal, sometimes crushing the animal, and drastically cooling the animal to death.

Zhang Guilian suggested that night-time heat preservation work should be done in greenhouses in areas where the temperature is relatively large, and measures such as covering grass thatch and covering insulation layers should be adopted. When necessary, geothermal wires and other methods should be used for artificial heating to prevent low-temperature freezing from damaging crops; After snowfall, it is necessary to promptly clear the snow on the roof of the shed, renovate and reinforce the livestock and poultry pens (pens), and actively do a good job of protecting the livestock from cold and warm to prevent the occurrence of frostbite.

According to CCTV News, according to the Snow Disaster Express issued by the Tongliao Emergency Management Bureau of the Inner Mongolia Autonomous Region, as of 16:30 on November 8, the snow disaster caused 8 banners, counties and districts, 50 Sumu town streets to be affected, and the affected population was 5609. 1 person died in the disaster; 176 dead animals (7 pigs, 56 cattle, and 113 sheep); 2,245 damaged sheds, 17 forage silos, 98 greenhouses, and 62 warehouses; 1 damaged factory, One bicycle shed, one playground roof, and 500 square meters of damage to the outpatient hall of Jian’an Hospital. The snow disaster caused a direct economic loss of 34,465,300 yuan.
