The cold spring is coming! These places will return to winter overnight.

The cold spring is coming! These places will return to winter overnight. The forecast shows that the northern region will start to cool down first, reaching the lowest point of about 18 today and tomorrow, and most areas in the central and eastern regions will cool down by 4 ~ 10℃, and the cold spring is coming! These places will return to winter overnight.

The cold spring is coming! These places will return to winter in 1 overnight. In the next three days (16 ~ 18), the central and eastern regions will experience "seasonal" cooling, with most areas cooling by 4 ~ 10℃, and the local cumulative cooling will exceed 20℃! The obviously high temperature in the south will drop sharply, and many places in the north will return to the cold winter. The national temperature "skydiving" competition is about to begin. See where the temperature will drop sharply and "land" overnight and return to winter?

The temperature of "skydiving" in Taiyuan and Zhengzhou North Group dropped by 265,438 0℃

Recently, many places in the north are as warm as spring. However, with the gradual advance of cold air from north to south, the cooling process will be started in the north one after another today and tomorrow, and it will drop to the recent low point around 18, with the cooling range in southern Hebei, central and western Henan, western Shandong and northern Shandong reaching more than 12℃.

Among the provincial-level cities, Taiyuan and Zhengzhou are the champions of the national skydiving competition. Yesterday, the highest temperatures in Taiyuan and Zhengzhou were 25℃ and 27℃ respectively, which were still as warm as early summer. By 17, the highest temperatures in the two places are only 4℃ and 6℃ respectively, and the cumulative temperature drop is 2 1℃, which is the worst among provincial-level cities in China. If the season changes overnight, the short sleeves will be replaced with cotton-padded jackets.

Jinan and Shijiazhuang are slightly inferior, but the cooling range is also around 15℃, and Beijing and Tianjin are around 13℃. After cooling, the highest temperature in the above areas is only single digits, which will be equivalent to the temperature level in early February all the year round. Especially in Tianjin, Beijing and Jinan, there will be light snow or sleet weather the day after tomorrow, which is the "standard" in winter.

Friendly reminder, this temperature "skydiving" competition, the competition in the northern group is fierce, only provincial-level cities with a cumulative decline of more than 15℃ are shortlisted, and we appeal to the short-listed friends to pay attention to the local early warning and forecast and add clothes in time!

From summer to winter, the temperature in Hefei, the southern group, dropped by 65438 09℃.

The "skydiving" competition in the southern group started late, but the excitement was not lost to the north. Zhang Juan, a meteorologist from China Weather Network, said that at present, most areas in the south seem to be in summer. For example, the highest temperature in Jiangnan today is close to 30℃, as hot as June. However, after the cooling starts tomorrow, the temperature will plummet, and it will drop in many places such as Jiangsu and Anhui, and it will be colder in the afternoon than in the morning.

Among the provincial-level cities, Hefei took the lead in "jumping" out of the temperature drop of 19℃, followed by Nanjing, with a drop of 18℃. In addition, the cooling ranges in Wuhan, Shanghai, Hangzhou and Nanchang all exceeded 10℃.

Focus on Hefei, Wuhan and Nanjing. Today, the highest temperatures in the three places will reach 29℃, 27℃ and 30℃, which is a proper summer, but tomorrow, the highest temperature will be in the early days of 10℃, and the temperature will "collapse" directly overnight, and a "jump" is two seasons!

China Weather Network warmly reminds us that although there are winners and losers in the "skydiving" contest, friends in the north and the south should pay close attention to it, especially when the temperature drops. There is a wide range of rain, snow and windy weather in the central and eastern regions, and the feeling of wet and cold will be more obvious. We should pay special attention to adding clothes to prevent cold and avoid catching a cold.

The cold spring is coming! These places will return to winter overnight. Have local friends already felt the influence of "cold spring"? But this is really just the beginning.

In the next three days, 16 ~ 18, a turning cold air will affect most parts of central and eastern China, resulting in a large-scale "seasonal" cooling, with a general cooling of 4 ~ 10℃ and a local cumulative cooling of more than 20℃!

A national temperature "skydiving" competition is about to begin.

According to the forecast, the northern region will start to cool down first, reaching the lowest point of about 18, and most of the central and eastern regions will cool down by 4 ~ 10℃, among which the cooling range in southern Hebei, central and western Henan, western Shandong and north China can reach above 12℃, and the local temperature can reach14 ~.

Of course, Taiyuan and Zhengzhou are not allowed in provincial capital cities. Yesterday, the highest temperatures were 25℃ and 27℃ respectively, and on 17, it will drop to 4℃ and 6℃ respectively, and the cumulative temperature drop will be 2 1℃, which will last for two seasons in one night.

In addition, the cooling range of Jinan and Shijiazhuang is about 15℃, and that of Beijing and Tianjin is about 13℃, all of which will return to single digits, and the minimum temperature will reach or approach 0℃.

There will be light snow or sleet weather in Tianjin, Beijing and Jinan tomorrow and the day after tomorrow.

Among the southern cities, Hefei will win with the cooling rate of 19℃, while the cooling rates of Wuhan, Shanghai, Hangzhou and Nanchang all exceed 10℃.

The highest temperatures in Hefei, Wuhan and Nanjing will reach 29℃, 27℃ and 30℃ today, and only 10℃ tomorrow.

According to the forecast of the Central Meteorological Observatory, from 08: 00 on March 16 to 08: 00 on March 17, there are small to medium snow or sleet in parts of northern and eastern Xinjiang, central and western Inner Mongolia, Hexi in Gansu, northern Qinghai and northern Heilongjiang, among which there is heavy snow (5-6 mm) in the northern part of Heilongjiang.

The cold spring is coming! These places will return to winter overnight from March 16 to March 17, and there will be an obvious precipitation cooling process in the central and eastern regions of China, with a greater rainfall intensity in the southern region. From the night of 16 to 18, there is obvious rain and snow in North China and the south of Northeast China.

Wide influence range and large cooling range.

Heavy precipitation in the south, obvious rain and snow in the north, with complex phases.

From March1June-March 17, there will be an obvious precipitation cooling process in the middle and east of China, and the rainfall intensity in the south is relatively high. From the night of 16 to 18, there is obvious rain and snow in North China and the south of Northeast China.

Affected by cold air and rain and snow, the temperature in most parts of central and eastern China dropped by 4 ~ 10℃ on17, and the temperature drop in southern Hebei, central and western Henan, western and northern Shandong exceeded 12℃.

After cooling, the minimum temperature line of 0℃ will be pressed southward to eastern Liaoning, southern Hebei and western Shanxi. Among them, the highest temperature in most areas such as Beijing-Tianjin-Hebei and Shanxi dropped below 4 C during the day.

Fu introduced that this process has the characteristics of wide influence range and large cooling range, and the temperature in the north of the middle and lower reaches of the Yangtze River will change from obviously high in the previous period to low. The rainfall in the south is strong and accompanied by a wide range of strong convective weather, and the rain and snow in the north are obvious and complex in phase.

Warm and cold meet, and the water vapor is abundant.

The result of cooperation between the upper trough and the surface cyclone.

Fu introduced that large-scale heavy precipitation in the south and rain and snow in the north are the results of the simultaneous influence of warm and humid airflow and cold air.

Take the rain in the south as an example. The warm and humid air flow from Indo-China Peninsula has brought warm spring, abundant water vapor and unstable energy to most parts of the south. The southbound cold air and warm and humid air meet and collide in the central and eastern regions of China, which brings heavy precipitation weather under the joint action of atmospheric unstable energy and other factors.

Along with the rainstorm, there are also strong convective weather such as short-term heavy precipitation, strong wind, hail and lightning.

However, Fu said that although the process was large in scope and strong in intensity, it did not belong to the extreme weather of this season. This is the result of the combined action of cold and warm air, water vapor, upper trough and surface Jianghuai cyclone.

Increase soil moisture and alleviate drought.

This kind of rain mass should be prevented and utilized.

Because the large-scale rainfall weather process in the south and the rain and snow weather process in the north are very "carrying goods", including rain and snow, strong winds, cooling, hail and so on. Coupled with the high temperature in most parts of the country in the early stage, the "cliff-like" cooling brought by this process will bring people the feeling of cold winter.

Fu suggested that strong convective weather such as rain, snow, strong wind and hail will have adverse effects on human health, living and production arrangements, transportation and travel, and it is necessary to take timely measures such as preventing cold and keeping warm and avoiding strong convective weather.

However, agricultural gas experts pointed out that the cooling process could not meet the standard of "cold spring" and had little impact on agriculture. Take the north as an example. At present, most areas in the north have just entered spring, winter wheat is in the wintering, turning green or rising period, with strong cold resistance and fruit trees have not yet blossomed. So this weather process is not enough to harm crops in the north. On the contrary, rain and snow are conducive to promoting the increase of soil moisture in wheat fields and getting up green.

Fu pointed out that for most areas in the south, drought has developed in some areas due to high temperature and little rain in the early stage. Rainwater in Jiangnan, Jianghan, Jianghuai, Guizhou and central Chongqing can alleviate the drought in most parts of the south and reduce the forest fire risk rating, but it is necessary to prevent short-term heavy precipitation from adversely affecting mountainous areas such as northern Hunan, southern Anhui and eastern Hubei.
