At present, a new year’s cold wave in China is brewing and ready to go. It is estimated that from December 28 to 31, this cold wave will sweep most of China from north to south, bringing “quick freezing” cooling and mixed rain and snow, which will be the strongest cold wave process affecting China this winter. By then, the temperature in 25 provincial capital cities will hit a new low this winter, and the Middle East will also meet the coldest New Year’s day in nearly eight years.
The Central Meteorological Observatory predicts that from December 28 to 31, a strong cold air will affect the central and eastern regions of China. At that time, the strong wind will cool down, rain and snow will appear one after another. In the eastern part of Northwest China, North China, Huanghuai, Jianghan, Jiangnan and other places, the temperature will reach 10-12 ℃, accompanied by 4-6 northerly winds and 7-8 gusts, which can be called the strongest cold wave this winter.
Zhang Juan, a meteorological analyst of China Weather Network, said that the cold wave process has the characteristics of quick freezing cooling, mixed rain and snow, which will “freeze” 80% of the territory, and the temperature of 25 provincial capital cities will hit a new low this winter. The most severe cooling period is from December 29 to 30. For example, in Northeast China, the lowest air temperature in Changchun and Harbin is only about – 26 ℃, which is extremely cold; while in North China, the lowest air temperature in underground weeks such as Beijing, Shijiazhuang and Tianjin may drop to about – 12 ℃.
The central and eastern regions will meet the coldest New Year’s day in nearly eight years
Affected by the cold wave, most parts of the country will cross the new year in sunny and cold weather this year, and most of the central and eastern parts will meet the coldest cross year day in nearly eight years. For example, the lowest temperature in Taiyuan on the 31st will reach – 23 ℃, which is comparable to that in Northeast China, the coldest New Year’s day since 1951; the lowest temperature in Jinan on the 31st will reach – 12 ℃, which will be the coldest since 1962; the lowest temperature in Hefei on the 31st will reach – 7 ℃, which will be the coldest since 2005.
The wind cold effect makes the body feel colder, and most of them are as cold as “39”
On December 28, it is expected that there will be 4-5 winds in the west of Inner Mongolia and the east of Northwest China. On December 29, there will be 4-6 winds in Inner Mongolia, North China, Jianghan, Jianghuai, Jiangnan and other places, and gusts in parts of Inner Mongolia and North China may reach 7-8. Although the process of this cold wave is not as strong as the Bawang cold wave in 2016, the wind cold effect will aggravate the degree of body feeling cold, so it is a proper quick freezing mode. For example, the lowest somatosensory temperature of Yinchuan process is close to – 20 ℃, and that of Beijing process is – 15 ℃; in the south, the lowest somatosensory temperature of Shanghai and Hangzhou is close to – 7 ℃, which is as cold as “three nine”.
In terms of rain and snow, due to the limited water vapor conditions, the intensity of rain and snow will not be too strong. The probability of the first snowfall in South China this year is not very high, and the dividing line of rain and snow hovers in the north and central part of the south of the Yangtze river. It is estimated that there will be light to moderate snow in the southeast of Northwest China, the south of North China and Huanghuai, rain to sleet in Jianghan, Jianghuai and the north of Jiangnan, light rain in the south central of Jiangnan and South China, and moderate rain locally.
Why is the cold wave so strong? Zhang Juan added that in fact, from around the 16th, the numerical prediction model has begun to show the process. In Siberia, cold air has been accumulating for a long time, and then the horizontal trough turns vertical, and the high-pressure trough guides the strong cold and high-pressure air mass to invade China, causing severe cooling.
In a word, at the beginning of next week, all parts of the country will spend the coldest time since this winter. It’s time to invite you to provide the ultimate cold protection equipment for this winter. Down jacket is the minimum respect for the cold wave, and hat, scarf, gloves and so on are indispensable.
