The Central Meteorological Observatory issued the earliest cold wave warning and cold wave forecast in history.

Affected by strong cold air, it is predicted that the temperature will generally drop by 8 ~ 12℃ in most parts of central and eastern China from12/0/4 to120/0/6, especially in central and eastern Inner Mongolia, northeastern China, most of Shaanxi, southwestern Shanxi, Huanghuai, Jianghuai, northern Hunan and northwestern Jiangxi. The temperature drop in central Inner Mongolia, eastern Heilongjiang, eastern Jilin, southern Henan, Hubei, central and northern Anhui can reach above 18℃. On the morning of June 6-7, the lowest temperature 0℃ line will be located in the north of North China and the middle of Northeast China, and the lowest temperature 10℃ line will be located in the northeast of Sichuan, the north of Hubei, the south of Henan and the south of Shandong. There will be strong winds of 7-8 in the northern and eastern seas of China, with gusts of 9- 10.

What happened when the Central Meteorological Observatory issued the earliest cold wave warning in history? Come and have a look with me.

The Central Meteorological Observatory1October 2 10 issued a blue warning of cold wave:

Affected by strong cold air, it is predicted that the temperature will generally drop by 8 ~ 12℃ in most parts of central and eastern China from12/0/4 to120/0/6, especially in central and eastern Inner Mongolia, northeastern China, most of Shaanxi, southwestern Shanxi, Huanghuai, Jianghuai, northern Hunan and northwestern Jiangxi. The temperature drop in central Inner Mongolia, eastern Heilongjiang, eastern Jilin, southern Henan, Hubei, central and northern Anhui can reach above 18℃. On the morning of June 6-7, the lowest temperature 0℃ line will be located in the north of North China and the middle of Northeast China, and the lowest temperature 10℃ line will be located in the northeast of Sichuan, the north of Hubei, the south of Henan and the south of Shandong. There will be 4~6 winds in the Yangtze River basin and its north, and gusts in high altitude areas and rivers and lakes can reach 7~8. There will be strong winds of 7-8 in the northern and eastern seas of China, with gusts of 9- 10.

Defense guide:

1, personnel should pay attention to add clothes to keep warm; In production, we should be prepared to defend against strong winds and cool down;

2, doors and windows, coamings, scaffolding, temporary structures and other structures that are easily blown by strong winds are fastened, and outdoor items that are easily affected by strong winds are properly placed;

3. Take shelter from the wind and notify outdoor workers to pay attention to safety;

4. Pay attention to the latest information reported by the media about gale cooling, so as to take further measures;

5, transportation, public security and other departments should do a good job in preparing for road icing in accordance with their duties.

Reading related to the earliest cold wave warning in history issued by the Central Meteorological Observatory;

The national cold wave warning is released, and both the north and the south are the key points! Authoritative forecast: local drop below 14 degrees.

10At 7: 00 a.m. on June 55438+05, according to the hourly temperature map, the blue area below 0 degrees in northern China has obviously expanded, especially in Inner Mongolia and Heilongjiang, where large areas below 0 degrees are connected together, and the new forest red in Daxinganling area in northwest Heilongjiang approaches-10 degrees, which means that the cold air we mentioned earlier began to move southward.

10At 8: 00 a.m. on June 55438+05, according to the ground weather map, a strong and broad high-pressure area developed in the Mongolian Plateau and Siberia in northern China, and the air pressure in the high-pressure center has exceeded 1052 hectopascals, which is the strongest high pressure since the second half of this year. It is a cold high pressure formed by a large number of cold and dense air masses sinking and accumulating near the ground. Compared with before, the intensity of cold high pressure is further strengthened.

1 1 in the morning, from the 24-hour temperature change chart, there is a large-scale cooling in the north of the Great Wall in China, and the 24-hour cooling range in many places in central and eastern Inner Mongolia exceeds 10 degrees, which means that cold air is infiltrating on a large scale and has begun to approach the northern part of the North China Plain.

Following the previous cold wave warnings issued by several provinces, autonomous regions and municipalities, the Central Meteorological Observatory issued the first cold wave blue warning this morning since the second half of this year. The Central Meteorological Observatory believes that the cold air currently affecting China is a strong cold air, which will also be the strongest cold air that China has encountered since the second half of this year. From 10 to 15, there will be strong winds and cool weather in the central and eastern regions of China. According to the forecast of the Central Meteorological Observatory, the temperature in North China, south-central Northeast China, Huanghuai, Jianghuai, Jianghan, Jiangnan and Guizhou will drop by 6 ~ 10 degrees successively, among which the temperature in eastern North China, southern Northeast China, western Shandong, eastern Jianghuai and northeastern Jiangnan will drop by 12 ~ 14 degrees.

There is no doubt that the north is the focus of this cold wave. At present, the power of the cold wave has begun to appear in Inner Mongolia and Northeast China. After that, it will be pushed to Beijing, south of the Great Wall and north of the North China Plain, where there may be a low temperature of about 0 degrees, which will be the lowest temperature since the second half of this year.

Although the low temperature in the south will not be worse than that in the north, the south is another key area affected by the cold wave. Compared with the north, the Yangtze River Delta and other places in the south feel a little warm and humid because of the warming in recent days. After the cold wave goes south, this warm and humid feeling in Jiangsu, Zhejiang, Shanghai and Anhui will be quickly eliminated, and there will be a cliff-like severe cooling. For example, according to the forecast of the Central Meteorological Observatory, the highest temperature in Shanghai may drop directly from about 30 degrees to about 17 degrees, and the lowest temperature may fall below 15 degrees. After that, the cold wave and the north wind will blow to the coast of South China, which will also cool South China again. Therefore, whether in the south or the north, we should pay attention to the weather changes in time and make a good response when the cold wave comes.
