Among them, the heavy snowfall areas in North China and Huanghuai are highly overlapping with the areas where heavy snowfall occurred on December 12, and the daily snowfall is extreme. Affected by the cold wave, the temperature in the central and eastern regions will continue to drop, and the minimum temperature in North China, Huanghuai and other places will be close to or fall below the extreme value of the same period in history.
From the 13th to the 15th, heavy snowfall will occur again in North China, Huanghuai, Northeast China and other places
It is expected that from the 13th to the 15th, there will be heavy to heavy snowfall in parts of central Inner Mongolia, northern and eastern Shaanxi, southern Shanxi, Hebei, Beijing, Tianjin, northern Henan, northeastern Shandong, Liaoning, central and eastern Jilin, and southeastern Heilongjiang, and heavy snowfall in eastern Liaoning, eastern Jilin, southern Shanxi, and northern Henan, and freezing rain in parts of central Shaanxi, southern Shanxi, and central and northern Henan; The cumulative snowfall in the above areas is 5~15 mm, and the local snowfall can reach 20~35 mm, and the new snow cover is 3~15 cm, and the local snowfall can exceed 20 cm. Among them, the main snowfall areas on the 13th were located in Shaanxi and North China, and the scope expanded to most of the above areas on the 14th. The daily snowfall in central Inner Mongolia, southern North China, eastern Jilin, and eastern Liaoning has certain extremes.
In addition, there are moderate to heavy rains in the eastern and southern parts of Huanghuai, Jianghuai, Jianghan and northern Hunan, with a cumulative precipitation of 10~40 mm, and locally up to 50~80 mm.
From the 14th to the 16th, there will be cold waves, strong winds and low temperature weather in the central and eastern regions
It is expected that from the 14th to the 16th, a new cold wave will affect most of our country, there will be 4~6 northerly winds in the central and eastern regions, and the temperature will drop by 8~12 °C, and some areas in central Inner Mongolia, North China, the southern part of Northeast China, Jiangnan, and northern South China will cool down to more than 14 °C, and there will be 6~8 winds in the eastern and southern sea areas, with gusts of 9~10. The minimum temperature in some parts of North China and northern Huanghuai will be close to or fall below the extreme value of the same period in history.

Meteorological disaster risk estimation
It is expected that from the 13th to the 15th, some areas in North China, Huanghuai, and the central and southern parts of Northeast China will have a high risk of heavy snowfall, low temperature rain and snow freezing, and the rain and snow weather will cause reduced visibility and snow and ice on the road, which will easily lead to traffic congestion or accidents, and snow in Jilin, Liaoning, southern Shaanxi, southern Shanxi, central and southern Hebei, northern Henan, central and northern Shandong may lead to the collapse of local simple buildings, greenhouses and livestock pens; Local freezing rain in central Shaanxi, southern Shanxi, central and northern Henan, Guizhou, and southern Hunan may cause short circuits or disconnections in power and communication facilities.
From the 14th to the 16th, there was a moderate risk of low temperature freezing damage in Jianghuai and the northern areas, and facility agriculture may suffer losses. Late weak seedlings in southeastern Hebei, northern Shandong, southeastern Henan, southern Anhui, Hubei and northern Hunan will suffer frost damage. In addition, some seas such as the Bohai Sea, the northern Yellow Sea, the southwestern East China Sea, the Taiwan Strait, and the eastern part of the South China Sea are at high risk of gale disasters.
Meteorologists remind
In this process, Shaanxi, Shanxi, Hebei, Beijing, Tianjin, Henan, Shandong, Jilin, Liaoning and other places have a high risk of heavy snow, low temperature rain and snow freezing disasters, and it is necessary to be vigilant against the adverse effects on transportation, urban operation and agriculture. In mid-December, the temperature in the central and eastern regions will continue to drop, and some areas in North China and Huanghuai will cool down sharply, and the temperature will reach or hit a new low in the same period in history.
