Five questions in the northeast, the cold wave of the Inner Mongolia strong snowfall weather | authority interpretation

  From November 7th to 8th, the strong snowfall caused by the cold wave of this round, mainly in Shandong, Hebei, Inner Mongolia and Northeast China, including large blizzards or extra large blizzards in the southeastern part of Inner Mongolia, central Liaoning Central, Jilin, etc. . Meteorologists are expected to reach 10 cm to 20 cm to 20 cm from Northeast China, and the local area can reach 40 cm. From November 6th to 8th, Liaoning Anshan has a large blizzard, and the snowfall in Anshan City Observatory reached millimeters (34 cm in Snow).

Anshan City 上海闵行区419会所 traffic is in the influence of Blizzard, and the bus stop is not available. (Figure / 文 萌 萌) At present, the Liaoning Provincial Meteorological Bureau has issued a red warning of Blizzard, especially from the 7th night, Shenyang City ushered in the rare weather of "Frozen Rain + Blizzard", the snow thickness reached 10 to 15 cm. Inner Mongolia Autonomous Region Meteorological Observatory, issued Blizzard Red Early Warning Signals, especially the Tongliao bureau, with a large blizzard, and the snow covered has more than 50 cm! Holly City, Inner Mongolia Autonomous Region ushered in a wide range of strong snowfall, and the meteorological department rolled information, providing support for the traffic control of national entrance and exit for the traffic control department. (Figure / Wen Ru Yu) It is understood that 上海徐汇桑拿哪家好 the amount of precipitation in Northeast is large, the precipitation is longer, due to the variation of temperature layer, the level of precipitation is very complicated, will experience many changes, rain, rain, snow, snow And even the rainy weather.

So, this cold wave in Northeast, Inner Mongolia, why is it so stronger? Xiaobian invites multiple experts to conduct authoritative interpretation. Integrated Meteorological Observation Product System (Tianheng Tianquan) National Ground Station 24-hour maximum snow deep surveillance product. Source: China Meteorological Bureau Meteorological Detective Center Production: Kangjiaqi Interviewee: Chief Expedition of Liaoning Province, Chief Expedition, Zhou Chunqing, Chief Prerequisite, Chief Prerequisite, Inner Mongolia Autonomous Region, Given, Northeast and Inner Mongolia, in this cold wave, the snowfall is so large What is the deep snow thickness? Zhou Chunxiao: Overall, it is a rapid development of multiple weather systems, and the fierce air and air is lengthened. Specific analysis, at 500hPa high-altitude, Northeast cold vortex strong development, low-grooved east to the northern, guide the development of the ground cyclone, form a deep low pressure system from the low-level to high altitude, strong power lift conditions; at the same time, southwest gas flow to Northeast China Well warm air, water vapor is abnormal. On the one hand, there is a strong power raising and water vapor branching; on the other hand, the system moves slowly, the snow is long, so there is a significant rain and snow, and the cooling process.

  Morning, November 8th, the impact of strong snowfall, the traffic of Xingcheng City, Liaoning Hulu City is blocked, and the public will go to work. (Figure / Wen Suzhen) Zhang Guilian: Mainly because of the high-altitude tank of Xinjiang cold air, slowly strengthen the cold vortex during the east shift. Since the cold vortex movement is slow, it is easy to cause a long-term rain, snow, wind and cooling weather.

  In addition, the thickness of the snow is also related to the water temperature, the water content of the snow.

For example, the snow thickness of the unit precipitation will change significantly with temperature. When the temperature of the temperature reaches from -6 ° C to -8 ° C, the snow depth produced by the unit snowfall will be maximized; with the temperature rise, the unit snowfall The amount of snow covers a significant decrease. During this snowfall, the water vapor conditions are good, the temperature is suitable, so the snow thickness is also deep.

  # 2 Whether the process is extremely extreme from snowfall or snow depth? Zhou Chunxiao: At present, the process snowfall in the western Liaoning region has exceeded the historical extreme value since 1951, and the snowfall in some parts of the Nort-Part is continued, and there is also possible possible to break through the history of history. Affected by Northeast Clear Vortex and Siberia, on November 6th, Liaoning Jianchang County has a strong snowfall, and the wind cools the weather. As of 12:00, the snowfall millimeter, the snow deep centimeter, the creation of weather records since Jianchang County in 1951.

(图 / 文 文 一) Zhang Guilian: This snowfall is relatively large, the wisdom of the western Inner Mongolia, the central and eastern part of the south, especially in the central part of the South and the eastern part of the south, of which Chifeng City Southeast, there is a large blizzard in the south of Tongliao City.

The biggest snowfall appears in the Tongliao City Cullenqi, reaching 60 mm, and the local snow has reached 50 cm. From the 5th to 7th, there were 32 stations in Inner Mongolia, showing extreme events, of which 3 of whom broke through the history of history, namely Xili Xiwuqi, Tongliao Naimanqi Qinglong Mountain and Kurenqi. # 3 What is the situation in the rain and snow in the region in addition to snowfall? Why is there a frozen rain in some areas? Zhou Chunxiao: During the process, Northeast and Inner Mongolia have emerged from rainfall, to the rain to rain, snow or frozen rain, and then turn the snow.

  In the early stage, the cold high pressure of the ground wedged the bottom layer in the west, and formed a "near ground cold pad".

Southwestern warm moisture flows on the cold pad, so that at 850hPa, the obvious anti-temperature layer is formed, especially in the middle and western part of Liaoning, "cold-warm-cold" structure is formed from low to high.

Therefore, Shenyang is mostly in the northern part of Anshan, most of Jinzhou, Most of the Yingkou, Fuxin, Liaoyang, Tieling, Panjin Southern Region and Fushun City, Huludao City has frozen rain.

  On November 7th to 8th, the national meteorological observatory of Xifeng County, Tieling County, Liaoning City, had a rainy weather, and the maximum diameter of the electric wire reached 35 mm. The maximum thickness of the ice is 8 mm. The county meteorological bureau staff is the electricity ice The measurement and weighing, this observation data will be the basis for the SF power line guarantee. (Figure / Wen Qin Road) # 4 What is the impact of this cold wave for agriculture? Does "white disaster" will appear? Zhang Guilian: The cold wave is a kind of disaster weather that is the most harmful to livestock. It has a serious threat to livestock with strong cold trend, and the temperature has declined to make livestock have a cold, bronchitis and other conditions, and easy Causes "sheep" (when the sheep is pressed into a pile of pests into each other), resulting in a pile of abortion, sometimes the livestock will still fall, and it will freeze the livestock.

  At the same time, this cold wave has a large snowfall, the south of Tongliao City, southern Chifeng City, the south of the southwest of Xilin Goli is more than 15 cm, and the facility agriculture will be affected by low temperature. If the late Snow can’t be melted as soon as possible, it will form a serious "winter snow", and the feed reserves of the pastoral area and half farm semi-animal husbandry areas.

  "White disaster" is also snowstorm. Pastoral snowstorming refers to a long time, maintaining a long time, burning pasture, causing livestock to eat normally, causing a large number of livestock to drop and died in the pastoral area. # 5 What is the suggestion for the current agriculture? Zhang Guilian: It is recommended that the greenhouse greenhouse in a large temperature increase is a good night-time insulation work, take measures such as grass, cover the temperature, and use the ground hotline and other methods to prevent low temperature refrigeration to cause damage to the crop; The area of ??the facility agriculture, reinforcing the resistance of crops in cold weather; to reinforce the facility structure in time, and try to cover the greenhouse with cold film.

  In the pastoral area, the shed and forage is resistant to natural disasters to ensure the material foundation of the livestock amu winter and spring. After snowing, it is necessary to clear the snow on the roof, renovation and reinforcement livestock house (column), and actively do a good job in the warmth of livestock. Preventing the frost of the livestock from frost. The herders should pay attention to the forage. In addition to the hay, they should feed a small amount of soybeans, corn, and enhance livestock anti-cold capacity, prevent it.
