It's very cold there now

Cold air is coming, and the temperature in 25 provincial-level cities will hit a new low.

With the arrival of cold air, the temperature in 25 provincial-level cities will hit a new low. According to the analysis, during the period from 17 to 18, 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.

Cold air is coming, and the temperature in 25 provincial-level cities will hit a new low of 1. At present, a new year's cold wave is brewing and ready to go. It is estimated that from February 28th 10 to February 28th1,this cold wave will sweep across most parts of China from north to south, bringing "quick freezing" cooling and rain and snow mixing, 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 usher in the coldest New Year's Day in the past eight years.

The strongest cold wave this winter swept through the central and eastern regions or "frozen through" 80% 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 February 28, 65438 to February 28, 3 1. At that time, strong winds, cooling rain and snow will appear one after another, and the temperature in the eastern part of northwest China, North China, Huanghuai, Jianghan and Jiangnan will reach 10 ~ 12℃, accompanied by northerly winds with gusts of 4 ~ 6.

Zhang Juan, a meteorologist from China Weather Network, said that the cold wave process has the characteristics of quick freezing and cooling, and it will "freeze through" 80% of the country, and the temperature in 25 provincial-level cities will hit a new low this winter. The most intense cooling period is 12 from February 29th to 30th. For example, 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 usher in the coldest New Year's Day in the past eight years.

Affected by the cold wave, most parts of the country will celebrate the New Year in sunny and cold weather this year, and most parts of the central and eastern regions will usher in the coldest New Year's Day in the past eight years. For example, the lowest temperature in Taiyuan on 3 1 day will reach -23℃, which is comparable to that in the northeast, and it is the coldest New Year's Day since 195 1. 3 1 day, the lowest temperature in Jinan will reach-12℃, which is the coldest since 1962. The minimum temperature in Hefei on 3 1 day will reach -7℃, which will be the coldest day since 2005.

The wind-cold effect is even colder, and most of them are as cold as "Sanjiu"

Cooling is accompanied by strong winds. It is estimated that there will be 4-5 winds in the west of Inner Mongolia and the east of Northwest China on February 28th, 65438. On the 29th, there will be 4-6 winds in Inner Mongolia, North China, Jianghan, Jianghuai and Jiangnan, and gusts in parts of Inner Mongolia and North China can reach 7-8. Although the cold wave process is not as strong as the overlord cold wave of 20 16, the wind-cold effect will aggravate the degree of somatosensory cold, so freeze the model appropriately. For example, the lowest somatosensory temperature in Yinchuan process is nearly -20℃, and the lowest somatosensory temperature in Beijing process is-15℃; In the south, the lowest somatosensory temperatures in Shanghai and Hangzhou are 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. The probability of the first snow in South China this year is not great, and the boundary between rain and snow lingers in the north-central part of the south of the Yangtze River. It is estimated that there will be small to medium snow in the southeastern part of the northwest, 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 16 years or so, the numerical forecast model has begun to show this process. In Siberia, cold air is constantly gathering and the power storage time is long. Then the horizontal trough turned vertical, and the high-altitude trough led the powerful cold and high-pressure air mass to invade China, causing severe cooling.

In short, at the beginning of next week, all parts of the country will spend the coldest period since this winter. It's time to bring out your ultimate cold-proof equipment for this winter. Down jacket is the minimum respect for the cold wave, and hats, scarves and gloves are indispensable.

Cold air is coming, and the temperature in 25 provincial-level cities will hit a new low. In a blink of an eye, the "heavy snow" of the traditional 24 solar terms has arrived. This week is still in the national weather stage (65438+February13-65438+February 19), and the pattern has changed. 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 up; Under the condition of static atmosphere, the accumulation of pollutants is also unfolding. However, its power is not as stubborn as before.

Experts said that according to the latest meteorological data analysis, during the period of 17-18, due to the influence of cold air, the temperature in many places in the central and eastern regions may hit a' new low' after autumn. However, the cooling of cold air comes and goes quickly. On the day of 19 -20, the temperature in many places will obviously rise again. In other words, in the case of overall warming, the rapid temperature drop is "inserted". This is also very similar to the common "warm winter" gesture in recent years, that is, when it is warm most of the time, it will be cold for a short time, but the average time and space are still warm.

It is worth noting that the insiders emphasized that the monitoring data showed that there was room for rent-seeking before the arrival of cold air. (14) In the morning, there was light to moderate pollution in Henan and its surrounding areas, corresponding to smog. Judging from the situation, (15) the smog in this area will continue to increase. 16 During the daytime, as the cold air moves eastward and southward, the smog pollution will weaken and dissipate during the transmission to the southeast. One is because of the wind, and the other is because of the precipitation.

Cold air is coming, and the temperature in 25 provincial-level cities will hit a new low. Recently, most parts of China are warmer, but a new cold air is ready to go, and the temperature will drop rapidly. Affected by this, the temperature in most parts of the central and eastern regions will drop by 6 ~ 10℃ from the night today (February 05 15), and the temperature in the northeast and east China will reach 12℃ or above. Temperatures in various places quickly dropped to a recent low in a day or two, and nearly 20 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. Pay attention to adjust clothes in time to prevent colds. # The cold air is coming again #

Cold air brought about a rapid drop in temperature, and the local temperature drop in Northeast China and East China exceeded 12℃

In the last ten days, the temperature in most parts of China is higher than that in the same period of normal years, among which, the temperature in parts of central and eastern Inner Mongolia and Northeast China is 6 ~ 8℃ higher. Today, many places are still warm and harmonious. The highest temperature in North China and Huanghuai is about 10℃, and in Jianghuai and Jiangnan, it is generally 15~20℃, and it is as warm as1/month all 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. Today, it will arrive at 18 at night. Due to the influence of cold air, the temperature in most parts of the central and eastern regions will drop by 6 ~ 10℃, and the temperature in the northeast and east China will reach above 12℃. Most areas in the north are accompanied by northerly winds of 4 ~ 5 grades, and gusts in some areas can reach 6 ~ 8 grades. The wind-cold effect is obvious due to the superimposed cooling.

According to Shi Yan, a meteorologist from China Weather Network, this cold air process has the characteristics of large influence range, fast cooling speed and easterly path. Tomorrow, cold air will mainly affect the north, and most areas will be cooled to varying degrees, especially in the eastern part of northwest China, eastern Inner Mongolia and northeast China, with the temperature in central Inner Mongolia and northern North China dropping by 6~ 12℃.

The day after tomorrow is the day with the largest cooling range and the most obvious decline, and the cooling in most parts of the central and eastern regions is obvious. The temperature dropped by 6~ 12℃ in the southeast of Northeast China and the east of Huanghuai. The temperature in eastern Jiangnan, southern China and eastern Yunnan dropped by 4~8℃, and the local temperature was about 10℃.

On 18, 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 20 provincial-level cities will hit a new low, with drastic changes in temperature and warmth.

Under the influence of cold air, the temperature in various places will quickly drop to a low point in a day or two. From 17 to 18, the temperature in the central, eastern and southwestern regions hit a new low in a large area, and nearly 20 provincial-level cities will hit a new low in the second half of this year. The lowest temperature of 0℃ is located in central Zhejiang, southern Anhui and northern Sichuan Basin.

Northeast China is the coldest. In many places, the highest temperature will drop to about-10℃, and the lowest temperature will drop below-15℃, among which the lowest temperature in Harbin will fall below -20℃ 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 0℃.

In the middle and lower reaches of the Yangtze River, the temperature changes dramatically. The highest temperature will drop from double digits to single digits, and the lowest temperature will be close to freezing point. Some places are as cold as three or nine. For example, the highest temperature in Hangzhou today exceeds 17℃, and it is only 8℃ on 18, and the lowest temperature will drop from 10℃ to 0℃.

Shi Yan warned that cold air came and went in a hurry. From this Sunday to the beginning of next week, the temperature will rise to normal or high, even warmer than before. For example, the highest temperature in Changsha today is above 16℃, which will drop to 1 1℃ on July 7 and rise to 20℃ on February 2 1 day. The temperature is like a roller coaster. Please pay attention to increase or decrease clothes in time to prevent colds.
