A medium-intensity cold air began to enter China today. Affected by it, in the next three days, most of Xinjiang, the central and eastern parts of the northwestern region, most of Inner Mongolia, and most of North China will have a temperature drop of 4 to 6 Â°C, and some areas will have a temperature drop of 8 to 10 Â°C. The northerly wind of ~6 grade, the wind power in the mountain pass area of â€‹â€‹Xinjiang can reach 7-8. At the same time, small to medium snow (rain) or sleet weather will occur in northern and southwestern Xinjiang, central and southeastern Inner Mongolia, northern North China, and most of the northeast.
Affected by cold air and tropical systems, there are small to moderate rains or showers in the coastal areas of southern China, Hainan, and Taiwan. Among them, some parts of eastern Hainan have heavy rain. In addition, some areas of the western Sichuan Plateau, Sichuan Basin, southwestern Shaanxi, and northwestern Guizhou have small to moderate rain (snow) or sleet.
In the alpine pastoral area, it is necessary to strengthen the cold and warmth of livestock and the transportation and reserve of forage materials to prevent the death of young animals, weak animals and sick animals. In areas such as Sichuan, Chongqing, Yunnan, Guizhou and other provinces where the soil is too wet, it is necessary to clear the ditch and spread the ditch in time to ensure the smooth transplanting of rapeseed and timely sowing of winter wheat, silkworm peas, etc., and to do the surface runoff after rainfall. Impede storage, increase the storage capacity of mountain ponds, reservoirs, leeches, winter paddy fields, etc., and reserve water resources for water production in winter and spring.
In the northern areas, facility agriculture should be well protected against wind, heat preservation and antifreeze. The pastoral areas should do a good job in preventing cold and wind protection of livestock, and pay close attention to the weather before freezing and sealing, and do a good job in the construction of farmland water conservancy projects such as grain drying, storage and autumn land preparation. Farmers and herdsmen's friends should add clothing according to the weather, keep warm and prevent colds and other diseases. Farmers and herdsmen who are burning coal in the north central area should pay attention to indoor ventilation and prevent gas poisoning.
