Two cold air will successively affect most of the central and eastern parts of China, and the temperature will turn obviously low.

　　China Weather Network News This week, two cold air "relays" will affect China, among which the cold air intensity will be stronger from January 6 to 8. After cooling, the temperature in the central and eastern regions will turn to a low level again, so the public should pay attention to the approaching forecast at any time and do a good job in cold prevention and warmth.

　　This week, two cold air strikes, and the temperature in most parts of the central and eastern regions will turn significantly lower.

　　Yesterday, the temperature in most parts of China began to rise slowly. Yesterday morning, the temperature line of 0℃ was significantly higher than the previous day, and the local temperatures in Jianghan and central Jiangnan rose by 6 ~ 8℃.

　　But starting this week, cold air will be active again, and there will be two cold air streams affecting our country. Among them, from the 4 th to the 5 th, due to the influence of weak cold air, the temperature in the eastern part of northwest China, North China, Huanghuai and Jianghuai will drop by 4 ~ 6 C; From 6th to 8th, due to the influence of strong cold air, the central and eastern regions will have a temperature drop of 6 ~ 8℃ from north to south, and the local temperature drop will be more than 10℃, with northerly winds of 4 ~ 6 in some areas.

　　Under the continuous suppression of two cold air, the temperature in the central and eastern regions will turn to a significantly low level again. Judging from the highest temperature, most areas in the north will take the lead in cooling to a low point from January 6 to 7. For example, the temperature in Harbin will continue to fall in the next three days, and the highest temperature may drop to-20 C on the 7 th. For the south, the warmth continued at the beginning of this week, and the temperature in various places will bottom out on the 7th to 8th. At that time, the highest temperature in the middle and lower reaches of the Yangtze River will drop to around 0℃, while that in South China will drop to around 10℃.

　　From January 6 to 8, the main body of cold air will begin to press southward, and there will be a wide range of low temperature innovations. The temperature in the central and eastern regions will go to a new level, and many places will usher in a new low temperature this winter. The public should pay attention to the approaching forecast, and the work of preventing cold and keeping warm cannot be relaxed.

　　In the next three days, it will be sunny and rainy in China, and there will be heavy snow in Xizang, Xinjiang.

　　In terms of precipitation, in the next three days, China will continue the weather pattern of sunny and rainy. It is estimated that today, the atmospheric diffusion conditions in southern North China, Huanghuai, Fenwei Plain and Sichuan Basin are general, with mild to moderate haze in some areas and severe haze in some areas. From tonight, due to the influence of cold air, the haze weather in the above areas gradually weakened and dissipated. From 5th to 10th, there were many cold air activities in the central and eastern regions, and there was no persistent haze.

　　The Central Meteorological Observatory predicts that there will be light snow or sleet in Liaodong Peninsula, southern Xinjiang basin and western mountainous areas of southern Xinjiang, western and southern Xizang, southern Gansu and eastern Jianghuai, among which there will be heavy snow in the southwest of Xizang. There are small to moderate rains in parts of eastern Jianghuai, eastern Jiangnan, eastern Southwest and northern Taiwan Province Island, among which there is heavy rain in the northeast of Taiwan Province Island.

　　In the middle of this week, with the southward movement of cold air, the range of rain and snow in the eastern part of southwest China and the south of the Yangtze River will be expanded. However, due to the poor water vapor transport conditions, the intensity and range of rain and snow weather in the future will be smaller than that in the last cold wave process, and the timeliness will be far away, so the public needs to pay attention.
