The temperature in most parts of the country will decline in fluctuations, with dry and cold in the north being the main one in the south being significantly wet and cold

The cold air affecting my country this week is relatively active, and the temperature in most areas will decline in fluctuations and gradually turn to a lower state than the same period in the previous year. Among them, the cooling in the north is more obvious, and the windy weather is mainly dry and cold. Since the early temperature rises in Northeast China, North China, Huanghuai and other places is significantly higher, the cumulative cooling rate is relatively large, generally reaching above 10℃. The low temperature will occur around the 21st. The highest temperature in the central and northern parts of the Northeast region will fall to less than minus 5℃, northern parts of North China will fall to near freezing point, around 5℃ in the central and southern parts, and less than 10℃ in the Huanghuai region.

In the south, affected by the combined influence of cold air and frequent cloudy and rainy weather, in the second half of this week, the highest temperature in the eastern part of the southwest region to most parts of Jiangnan, Jianghuai and other places are mostly less than 10℃. Among them, the wet and cold feeling in many places in Guizhou and Hunan will run throughout the day.

The meteorological department reminds that most of the north are dry and windy, and the wind-cold effect is obvious. Everyone needs to take measures to prevent cold and keep warm when going out, especially to keep warm on the head and neck. You can eat more pears, tremella, yam and other foods to relieve dryness; the south is obviously wet and cold, so you should pay attention to the safety of using fire and electricity when heating indoors.
