What is the snowfall of the blizzard? There will be a large-scale blizzard in the northeast.

Blizzard is a common natural weather. In northern China, there is likely to be a snowstorm in winter, so we need to know how much snow falls. Will there be a large-scale blizzard in Northeast China? Many friends want to know the answer to this question. Let's have a quick look.

What is the snowfall of the blizzard? Meteorology has strict regulations on snowfall, which is completely different from the standard of rainfall. The level of snowfall is not divided according to the thickness of snow on the ground. Snow quantity is a measure measured by meteorological observers after melting the collected snow in a certain standard container. Because the size, shape and density of the snow falling on the ground are different, according to the amount of water after the snow melts, the snowfall is divided into multiple grades from low to high. There are strict regulations on snowfall in meteorology. Like rainfall, it refers to the amount of snowfall in a certain period of time. There are different standards for 24 hours and 12 hours. In the weather forecast, the weather is usually predicted during the day or at night, which mainly refers to the 24-hour snowfall. Blizzard means that the daily snowfall (melting into water) is greater than or equal to10mm.

There will be a large-scale blizzard in the northeast today and tomorrow, and the center of gravity of snowfall will gradually shift to the northeast. In this precipitation, the snowfall intensity in Northeast China is relatively strong, and there may be snowfall above blizzard in eastern Inner Mongolia, western Jilin and southern Heilongjiang, with local snowstorms. Today night to the day after tomorrow, southeast Inner Mongolia, west Jilin, west Heilongjiang and other places. In some areas, there are big blizzards and local blizzards. The influence of the cold wave continues. The latest yellow warning of cold wave issued by the Central Meteorological Observatory shows that there will be a temperature drop of 8 ~ 10℃ in parts of eastern Huanghuai, eastern Jianghuai, eastern and southern Jiangnan and central and eastern South China. It is estimated that there will be heavy snowstorms in most areas of southeastern Inner Mongolia, Liaoning, western and southern Jilin, central and southwestern Heilongjiang from 08: 00 to 08: 00 on October 8/kloc-0+065438. Among them, some areas in southeastern Inner Mongolia, northwestern Liaoning, western Jilin, central and southwestern Heilongjiang have heavy snowstorms or extremely heavy blizzards (20 ~ 48 mm). The newly added snow depth in some areas above 10 ~ 20cm, and the local area can reach more than 30 ~ 40cm.

How is the level of snow divided into light snow? It means that when it snows, the horizontal visual distance is equal to or greater than 1000m, the ground snow depth is less than 3cm, the 24-hour precipitation level, and the snowfall is between 0.1~ 2.4 mm. Snow: it means the horizontal visual distance between 500 ~ 1000m when it snows, and the ground snow depth is 3 ~ 5cm. 24-hour snowfall is 2.5 ~ 4.9 mm. Heavy snow: refers to the poor visibility when it snows, the horizontal visual distance is less than 500 meters, the ground snow depth is equal to or greater than 5 cm, and the 24-hour snowfall reaches 5.0 ~ 9.9 mm. If there is snowfall but no snow is formed, it is generally called "sporadic light snow". When the snowfall reaches 10.0 ~ 19.9 mm in 24 hours, it is a blizzard, 20.0 ~ 29.9 mm is a blizzard, and more than 30.0 mm is a blizzard.

Matters needing attention in snowstorm weather: close doors and windows and fasten outdoor structures. Residents should pay attention to adding clothes to keep warm, especially for the elderly and infirm patients. Take warm and anti-skid measures when going out, and be careful to slip and fall. Drivers should take anti-skid measures, pay attention to road conditions, obey orders and drive slowly. Herdsmen should drive wild animals into sheds to feed them. Ships should take shelter from the wind, and outdoor workers such as high altitude and water should stop working. People in dangerous houses should be evacuated quickly, especially in the case of snowstorm. Beware of gas poisoning, especially for residents who use coal stoves for heating. If you are trapped by a snowstorm, call for help as soon as possible.
