From an atmospheric point of view, the blizzard formed due to its special atmospheric circulation situation. North of the Yangtze River is the Omega circulation pattern, and it stays that way for a long time. At lower latitudes, it is the Dimensional Stream [the east-west flow that prevails along the circle of dimensions]. This ribbon of air constantly fluctuates, transporting warm, moist air from the Bay of Bengal and the South China Sea. The cold air moves southward and combines with the warm moist air to produce freezing rain and snow in the south. The road traffic safety risk index is high in snowy weather.
When starting out on an icy road, slowly release the brake or let go of the clutch and wait for the vehicle to move slowly before gently pressing down on the gas. Don't start on a big foot of gas, which can easily lead to wheel slippage and side-slip phenomenon. Drivers should keep 2 to 3 times the usual distance from the car in front of them, try to drive in the ruts left by the car in front of them, and be ready to brake in advance; slow direction, and appropriately increase the turning radius. Strong snowfall is also prone to white disasters, adversely affecting agriculture and animal husbandry. Farmers and herders should take the following precautions.
Regional greenhouses with large temperature drop should do a good job of nighttime insulation, take measures such as covering straw thatch, covering insulation, etc., and if necessary, use the ground hot line and other means of artificial heating, to prevent low-temperature freezing damage to the crops caused by the loss; in the area of the snowfall, we should do a good job of the facilities of the artificial lighting of agriculture to enhance the cold-resistant capacity of the crops. In windy areas, the structure of the facility should be reinforced in a timely manner, as far as possible, the use of cold film to cover the greenhouse. Blizzard red warning signal means that there will be more than 15 millimeters of snowfall within six hours, or is expected to have more than 15 millimeters of snowfall, and snowfall continues, may or will have a greater impact on transportation or agriculture.
