In the past weekend, most parts of China were in a period of intermittent cold air, and the temperature rose significantly. Cold air is already on its way, though! This week, two cold air will be interspersed with the impact of our country, the temperature in many places in the north will experience a rollercoaster rise, of which the first cold air will be "shipped" tomorrow (December 5), bringing strong winds, cooling, rain and snow, sand and dust and other "weather" to the north The second cold air hit on the 9th, and many places in the north will cool down like a change of season, and many places in North China may usher in the first snow this winter.
Two waves of cold air are coming one after another, and the temperature in the northeast and other places will experience a rollercoaster rise.
This week, there will be two waves of cold air in succession, and the affected area will be mainly concentrated in the north. Among them, the first cold air will be "shipped" tomorrow, with strong intensity, which will bring strong winds, cooling, rain, snow and sand and dust to many places in the north. Around the 9th, the second supplementary cold air will come one after another, and at that time, many places in the north will cool down again.
Meteorological analyst Li Liang introduced that in this round of cooling process, Inner Mongolia and Northeast China will be the core areas of cooling, of which the eastern part of Inner Mongolia, Heilongjiang and other places can cool down by 10 to 14. Around the 7th, with the end of the influence of cold air, the above-mentioned areas will usher in a big warm-up, and on the 9th, with the appearance of the second cold air, it will once again experience a cold and warm transition. Cold air is interspersed with influences, and the temperature in Inner Mongolia and Northeast China will ride a roller coaster and usher in the first ups and downs. In provincial capital cities, such as Harbin, today's maximum temperature will rise to 1, tomorrow by the first cold air, will fall to -6, 8 will return to above freezing, 9 to 10, with the second cold air unfolding, will drop to -15, a day apart from early spring back to deep winter, the maximum temperature will refresh this winter's new low.
Although the temperature fluctuations in North China, Huanghuai and other places are not as obvious as those in Northeast China, many places are also like changing seasons every other day. In the next four days, these places will warm up all the way, affected by the second cold air, around the 10th, Beijing-Tianjin-Hebei, Shandong, Henan and other places will welcome a significant transition of cold and warm. Like Zhengzhou, the maximum temperature can rise to 23 on the 8th, and it will fall by 6 on the 10th, and the drop can reach 17 in two days.
On the whole, the first cold air affected area is more northerly, and the temperature in most areas south of the Yellow River will still be at a higher level than usual, from the 7th to the 8th, the temperature will reach a stage high, and the northernmost part of the maximum temperature 20 line will be lifted north to the north of Henan and the central part of Shandong. However, after the second wave of cold air appears, many places in the north will welcome bungee jumping, and the weather pattern of high temperatures will be reversed. The public needs to pay attention to temperature changes, flexibly grasp the rhythm of dressing, and stay away from the risk of colds.
Wind, dust, rain and snow all hit together! There is a lot of sand and dust in the northwest, and many places in North China may welcome the first snow this winter.
In addition to the significant cooling brought by the cold air, it is expected that from tonight to the 6th, there will be strong winds of 4 to 6 in the eastern part of Northwest China, Inner Mongolia and other places, with local gusts of 9 to 10. Affected by it, there will be more sand and dust weather in the eastern part of Northwest China, and Huanghuai and other places will be affected by sand and dust transmission in the later period, so you need to pay attention to protection when you go out. Is it normal for there to be dust in December? Li Liang introduced that in December all year round, as the temperature drops, the source of sand is frozen and lacks the "raw materials" of sand and dust. However, since this winter, the temperature in most parts of our country has been warm, and the sand source areas have not been frozen.
In addition, a second stream of cold air will work with warm and humid airflow to induce widespread rain and snow. The 10th will be the core period of snowfall, Hebei, Shanxi and other places may be heavy snowfall, Beijing, Tianjin and other places also have the opportunity to see snowflakes falling, welcome the first snow of this winter. Li Liang introduced that this is mainly due to the formation of a cold high pressure over North China and Northeast China around the 10th, which provides dynamic conditions for snowfall, and at the same time, the easterly wind backflow will transport water vapor from the Yellow Sea and the Bohai Sea to this area, providing sufficient water vapor conditions, thus forming snowfall. The timeliness is far away, and there are still uncertainties about whether the snowfall will be realized, so the public needs to pay attention to the nowcast and take relevant preventive measures.
