Among them, central Inner Mongolia, eastern Heilongjiang, eastern Jilin, southern Henan, Hubei, and Anhui The temperature drop in some areas such as central and northern China can reach more than 18℃. From the morning of the 6th to the 7th, the minimum temperature line of 0℃ will be located in the northern part of North China and the central part of Northeast China, and the minimum temperature line of 10℃ will be located in the northeastern part of Sichuan, northern Hubei, southern Henan, and southern Shandong. There will be strong winds of magnitude 7 to 8 and gusts of magnitude 9 to 10 in the northern and eastern seas of my country.

Follow me to find out what happened when the Central Meteorological Observatory issued the earliest cold wave warning in history.

The Central Meteorological Observatory issued a cold wave blue warning at 10:00 on October 2:

Affected by the strong cold air, it is expected that from 14:00 on October 2 to 20:00 on October 6, Temperatures generally dropped by 8 to 12 degrees Celsius in most areas of central and eastern Inner Mongolia, most of Shaanxi, southern Shanxi, Huanghuai, Jianghuai, northern Hunan, northern Jiangxi, southern Anhui, southern Jiangsu, and northern Zhejiang. ~16℃, among which the cooling rate in some areas such as central Inner Mongolia, eastern Heilongjiang, eastern Jilin, southern Henan, Hubei, and central and northern Anhui can reach more than 18℃. From the morning of the 6th to the 7th, the minimum temperature line of 0℃ will be located in the northern part of North China and the central part of Northeast China, and the minimum temperature line of 10℃ will be located in the northeastern part of Sichuan, northern Hubei, southern Henan, and southern Shandong. There will be winds of magnitude 4 to 6 in the Yangtze River Basin and areas north of it, and gusts in high altitude areas and rivers and lakes can reach magnitude 7 to 8. There will be strong winds of magnitude 7 to 8 and gusts of magnitude 9 to 10 in the northern and eastern seas of my country.

Defense guidelines:

1. Personnel should pay attention to adding clothes to keep warm; be prepared for strong winds and cooling weather in production;

2. Doors, windows, Tighten hoardings, scaffoldings, temporary structures and other structures that are easily blown by strong winds, and properly place outdoor items that are easily affected by strong winds;

3. Take shelter in a wind-proof place and notify outdoor workers Pay attention to safety;

4. Pay attention to the latest information about strong wind and cooling reported by the media so that further measures can be taken;

5. Transportation, public security and other departments should respond to road icing in accordance with their responsibilities Preparation.

The Central Meteorological Observatory issued the earliest cold wave warning in history. Related reading:

National cold wave warning is issued, focusing on the north and the south! Authoritative forecast: Partial drop of more than 14 degrees

At 7 a.m. on October 15, according to the hourly temperature map, the blue area below 0 degrees in northern my country has significantly expanded, especially in Inner Mongolia and Heilongjiang. , a large area below 0 degrees is connected. Xinlin Huzhong in the Daxinganling area in northwest Heilongjiang is even approaching -10 degrees. This is the cold air we mentioned before that has begun to move south.

At 8 a.m. on October 15, according to the ground weather map, a strong and broad high-pressure area developed in the Mongolian Plateau and Siberia to the north of my country. The central pressure of the high-pressure has exceeded 1052 hPa. This is The strongest high pressure that has appeared since the second half of this year is a cold high pressure formed by a large amount of cold and dense air masses sinking and accumulating near the ground. Compared with before, the intensity of the cold high pressure has further strengthened, indicating that a large amount of cold air has accumulated. At present, cold air has begun to affect Inner Mongolia and other places, bringing a strong chill.

At 11 a.m., according to the 24-hour temperature change map, a large-scale cooling area has appeared in the area north of the Great Wall of my country. The 24-hour temperature drop in many places in central and eastern Inner Mongolia has exceeded 10 degrees. , this is the cold air that is penetrating in a large scale and has now begun to approach the northern part of the North China Plain.

Following the previous cold wave warnings issued by many provinces, autonomous regions and municipalities, the Central Meteorological Observatory issued the first cold wave blue warning since the second half of this year this morning. The Central Meteorological Observatory believes that the cold air currently beginning to affect our country is a strong force. Cold air, this will also be the strongest cold air our country has encountered since the second half of this year. Starting from October 15, strong winds and cooling weather will occur in central and eastern my country. According to the forecast of the Central Meteorological Observatory, North China, central and southern Northeast China, Huanghuai, Jianghuai, Jianghan, Jiangnan and Guizhou will successively cool down by 6 to 10 degrees. Among them, eastern North China, southern Northeast China, western Shandong, eastern Jianghuai, and northeastern Jiangnan The temperature in some areas such as Japan will drop by 12 to 14 degrees, and the local temperature will drop by more than 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 many places in the Northeast. After that, it will advance to the south of the Great Wall and Beijing in the northern part of the North China Plain. Low temperatures around 0 degrees are likely to occur in plain areas, which will be the lowest temperature since the second half of this year.

Although the low temperature in the south is not worse than in the north, the south is also another key area affected by the cold wave. Compared with the north, the Yangtze River Delta and other places in the south have a warm and humid feeling due to the rising temperatures in recent days. After the cold wave moves southward, this warm and humid feeling in Jiangsu, Zhejiang, Shanghai and Anhui will be quickly eliminated, and a cliff-like violent crisis will occur. To cool down, for example, the forecast from the Central Meteorological Observatory shows that the highest temperature in Shanghai may drop directly from around 30 degrees to around 17 degrees, and the lowest temperature may drop below 15 degrees. After that, the cold wave north wind will blow into the coast of South China, cooling South China again. Therefore, whether in the south or the north, we must pay attention to weather changes in time and be prepared when the cold wave comes.
