When cold air comes, the temperature in 25 provincial-level cities will hit a new low.

When cold air comes, the temperature in 25 provincial-level cities will hit a new low. According to analysis, during the 17th-18th, due to the influence of cold air, the temperature in many places in central and eastern China may hit a new low after autumn. Cold air is coming, and the temperature in 25 provincial-level cities will hit a new low, and the temperature in 25 provincial-level cities will hit a new low. 1

At present, a New Year's cold wave is brewing and ready to go. It is predicted that this cold wave will sweep across most parts of China from north to south from December 28th to 31st, bringing "quick-frozen" 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-level cities will hit a new low this winter, and the central and eastern regions will also welcome the coldest New Year's Day in the past eight years.

the strongest cold wave this winter has swept across the central and eastern regions or "frozen through" 8% of the country

The Central Meteorological Observatory predicts that there will be a strong cold air affecting the central and eastern regions of China from December 28th to 31st, when strong winds will cool down and rain and snow will appear one after another, with the temperature reaching 1 ~ 12℃ in the eastern part of northwest China, North China, Huanghuai, Jianghan and Jiangnan, accompanied by northerly winds of 4 ~ 6 grades and gusts.

Zhang Juan, a meteorologist of China Weather Network, said that the cold wave process has the characteristics of quick-freezing cooling and mixed rain and snow, which will "freeze through" 8% of the country and the temperature in 25 provincial-level cities will hit a new low this winter. The most intense cooling period is from December 29th to 3th, like the northeast, where the lowest temperature in Changchun and Harbin is only about -26℃, which is extremely cold. The lowest temperature in North China, such as Beijing, Shijiazhuang and Tianjin, may drop to around -12℃ next week.

most of the central and eastern regions will welcome the coldest New Year's Day in the past eight years

Affected by the cold wave, most of the country will celebrate the New Year in sunny and cold weather this year, and most of the central and eastern regions will welcome the coldest New Year's Day in the past eight years. For example, the lowest temperature in Taiyuan on the 31 ST will reach-23 C, which is comparable to the northeast, and it is 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 reached -7℃, which will be the coldest since 25.

the wind-cold effect is even colder, and most of them are as cold as "March 9"

The cooling is accompanied by strong winds. It is expected that there will be 4-5 winds in the west of Inner Mongolia and the east of northwest China on December 28th, and 4-6 winds will appear in Inner Mongolia, North China, Jianghan, Jianghuai, Jiangnan and other places on the 29th, and gusts in parts of Inner Mongolia and North China may reach 7-8. Although the cold wave process is not as strong as the overlord cold wave in 216, the wind-cold effect will aggravate the degree of somatosensory cold and the proper quick-freezing mode. For example, the lowest somatosensory temperature in Yinchuan process is nearly -2℃, and the lowest somatosensory temperature in Beijing process is-15℃; In the south, the lowest somatosensory temperature in Shanghai and Hangzhou is also close to -7℃, as cold as "Sanjiu".

in terms of rain and snow, due to the limited water vapor conditions, the intensity of rain and snow will not be too great, and the probability of the first snowfall in South China this year is not great. The boundary between rain and snow lingers in the central and northern parts of the south of the Yangtze River. It is estimated that there will be small to medium snow in the southeast of northwest China, southern North China and Huanghuai, rain to sleet in Jianghan, Jianghuai and northern Jiangnan, light rain in south-central Jiangnan and southern China, and local rain.

why is this cold wave so strong? Zhang Juan added that in fact, from around 16th, the numerical forecast model has begun to show this process. In Siberia, cold air keeps gathering, and the energy storage time is long. Then the horizontal trough turns vertical, and the high-altitude trough guides the powerful cold and high-pressure air mass to invade our country, causing severe cooling.

In short, the coldest time since this winter will be spent in all parts of the country at the beginning of next week. It's time to invite out the ultimate cold protection equipment you prepared for this winter. Down jackets are the minimum respect for the cold wave, and there is no shortage of hats, scarves and gloves. Cold air is coming, and the temperature in 25 provincial-level cities will be 2

In a blink of an eye, the traditional "heavy snow" of 24 solar terms has arrived. It is still in the national weather stage this week (December 13th-December 19th) where three seasons coexist, and the pattern has seen new changes. In the opinion of experts, cold air combined with typhoon will become the "protagonist". The temperature in most areas shows a trend of rising first, then falling and warming; Under the static and stable atmospheric conditions, the accumulation of pollutants is also unfolding. However, its forces are not as stubborn as before.

experts said that according to the latest meteorological data analysis, during the 17th-18th period, due to the influence of cold air, the temperature in many places in central and eastern China may hit a new low after autumn. However, the cooling of cold air comes and goes quickly. On the 19th-2th, the temperature in many places will rise significantly again. In other words, in the overall warmer, "insert" a rapid drop in temperature. This is also very similar to the common gesture of "warm winter" in recent years, that is, when it is warm most of the time, it will be cold rapidly and briefly, but the average time and space is still warm.

It is worth noting that people in the industry emphasized that the monitoring data showed that there was room for "rent-seeking" before the cold air arrived. (14th) In the morning, there was mild-moderate pollution in Henan and its surrounding areas, corresponding to haze. Judging from the situation, (15th), the haze in this area will continue to increase. During the daytime on the 16th, as the cold air moves eastward and southward, the haze pollution will weaken and dissipate during the transmission to the southeast. One is because of the wind, and the other is the precipitation. The cold air is coming, and the temperature in 25 provincial-level cities will hit a new low. 3

Recently, most of our country is warmer, but a new cold air is ready to go, and the temperature will drop rapidly everywhere. Affected by it, today (December 15th) from night to 18th, the temperature will drop by 6 ~ 1℃ in most parts of central and eastern China, and it will reach above 12℃ in northeast China and east China. Temperatures in various places quickly dropped to a recent low within a day or two, and nearly 2 provincial-level cities will hit a new low in the second half of this year, with drastic changes in temperature and warmth in many places. It is necessary to pay attention to timely adjustment of clothing to guard against colds. # Cold air is coming again #

Cold air has brought about a rapid drop in temperature, and the temperature in Northeast China, East China and other places has dropped by more than 12℃

In the last ten days, the temperature in most parts of China is higher than normal, among which the temperature in parts of central and eastern Inner Mongolia and Northeast China is higher by 6 ~ 8℃. Today, many places are still warm. The highest temperature in North China and Huanghuai is about 1℃, and it is generally 15~2℃ in Jianghuai and Jiangnan, which is as warm as November all the year round.

However, a new cold air is gaining momentum, and the temperature in many places in China will drop rapidly, reversing the warmer pattern. From today's night to the 18th, due to the influence of cold air, the temperature will drop by 6 ~ 1℃ in most parts of the central and eastern regions, and it will reach above 12℃ in the northeast and east China. Most areas in the north are accompanied by northerly winds of 4 ~ 5 grades, and gusts in some areas can reach 6 ~ 8 grades, which are superimposed and cooled, and the wind-cold effect is obvious.

According to Shi Yan, a meteorologist of China Weather Network, this cold air process has the characteristics of large influence range, fast cooling speed and eastward path. Tomorrow, cold air will mainly affect the north, and most areas will have different degrees of cooling, especially in the eastern part of northwest China, eastern Inner Mongolia and northeast China, among which, central Inner Mongolia and northern North China will have a temperature drop of 6~12℃.

the day after tomorrow is the day with the largest cooling range and the most obvious decline, and most of the central and eastern regions have obvious cooling. There are 6 ~ 12 C cooling in the southeastern part of Northeast China and the eastern part of Huanghuai; The temperature in eastern Jiangnan, southern China and eastern Yunnan dropped by 4~8℃, and the local temperature was about 1℃.

on the 18th, the temperature in many places in the south will continue to drop, and the cooling range of local processes such as eastern Anhui, north-central Jiangsu and south-central Zhejiang can reach more than 12℃.

The temperature in nearly 2 provincial-level cities will hit a new low, and the change between cold and warm will be fierce

Under the influence of cold air, the temperature in various places will quickly drop to a low point within one or two days. From 17th to 18th, the temperature in central, eastern and southwestern regions will hit a new low in a large area. * * * Nearly 2 provincial-level cities will hit a new low in the second half of this year, and the lowest temperature line of ℃ is located in central Zhejiang, southern Anhui and northern Sichuan Basin.

the northeast region is the coldest. In many places, the highest temperature will drop to around -1℃, and the lowest temperature will drop below -15℃, among which the lowest temperature in Harbin will fall below -2℃ for the first time in the second half of this year. The highest temperature in central and southern North China and Huanghuai area will also hover around ℃.

The middle and lower reaches of the Yangtze River have experienced a drastic change between cold and warm. The highest temperature will drop from double digits to single digits, and the lowest temperature will be near freezing point. In some places, it is as cold as three or nine. For example, the highest temperature in Hangzhou today is over 17℃, only 8℃ on the 18th, and the lowest temperature will also drop from 1℃ to ℃.

Shi Yan reminded that the cold air came and went in a hurry. From Sunday to the beginning of next week, the temperature in various places will rebound to normal or high, even warmer than before. For example, the highest temperature in Changsha today is above 16℃, which will drop to 11℃ on the 17th and rise to 2℃ on the 21st. The temperature is like a "roller coaster". Please pay attention to increasing or decreasing clothes in time to guard against catching a cold.
