On October 2,
Central Meteorological Observatory issued a cold wave blue warning. This is the earliest cold wave warning issued in the second half of the year since the early warning release mechanism was officially launched in 2010. At the same time, the high temperature weather in the south continues. The Central Meteorological Observatory has issued a high temperature yellow warning for 3 consecutive days. This is also the first time that a cold wave warning and a high temperature warning have been issued at the same time!
"Cliff-style cooling" has a wider impact
According to the WeChat public account of the Central Meteorological Observatory, as of the 6th, the temperature in most parts of the central and eastern parts of the country will generally drop by 8 to 12 ℃. Henan, southern Shandong, Jiangsu, Anhui, Hubei, northern Hunan, northern Jiangxi, northern Zhejiang and other places cooled by 12-16 °C, central Inner Mongolia, eastern Heilongjiang, eastern Jilin, southern Henan, Hubei, central and northern Anhui, and central and northern Jiangsu, etc. In some areas, the cooling rate can reach more than 18 ℃.
From the morning of the 6th to the 7th, the minimum temperature line of 0°C will be located in northern Shanxi, northern Hebei, and northern Liaoning, and the minimum temperature line of 10°C will be located in northeastern Sichuan, northern Hubei, southern Henan, and southern Shandong. During the
period, the daily maximum temperature in provincial capital cities such as Nanjing, Hefei, and Wuhan will drop from 37-39°C on the 2nd to 13-15°C, and the minimum temperature will drop from 26-28°C to 11-13°C.

not only cools rapidly, but also cools quickly in just two days. Within, you can experience the changes of two or even three seasons, directly from short-sleeved sweaters. So, there is not much time left for the boys to pull out thick clothes!
Is cold air and cold wave the same thing?
Not all cold air is called a cold wave.
The relationship between cold air and cold wave, people often confuse these two concepts. China Weather Network Meteorological Analyst Min Yuqiu introduced that cold wave is a kind of cold air, not all cold air is cold wave, it is the "king" of cold air.
In the sense of meteorology , there are strict "thresholds" for cold waves. Yang Shunan, deputy chief forecaster of the Central Meteorological Observatory, introduced that the cold wave weather process is a large-scale strong cold air activity process. According to the national standard for cold air, the daily minimum temperature in a certain place should be cooled by ≥8°C within 24 hours, or the cooling rate within 48 hours should be ≥10°C, or the cooling rate within 72 hours should be ≥12°C, and the daily minimum temperature of the place should be ≤ The cold air activity of 4°C is a cold wave.
However, due to the influence of geographical environment and climatic conditions, the cold wave standard will also be different. Why did
issue a warning when the cold air did not meet the cold wave standard this time?
Zhang Tao, chief forecaster of the Central Meteorological Observatory, explained that before and after the National Day this year, the temperature in the north and south of my country has increased significantly, and the temperature in many places has reached new highs. . Coinciding with the "November" holiday, severe cooling may have an adverse impact on transportation, production and life. From the perspective of service, forecasters can issue cold wave warnings as appropriate, which has happened in the past.
To achieve "two plus three defenses" in the defense against cold waves
The cold wave is a large-scale disastrous weather process, which will cause large-scale rapid cooling, strong winds and rain and snow weather, which are harmful to agriculture, animal husbandry, transportation, electricity and human health.have a relatively large impact. In order to prevent and mitigate meteorological disasters, before a cold wave strikes, the meteorological department will issue a cold wave warning to remind the public to take precautionary measures. Once
receives the cold wave warning issued by the meteorological department, the public should pay attention to taking corresponding defensive measures to achieve "two plus three defenses".
Adding clothes: When the temperature drops sharply, pay attention to adding clothes to keep warm, especially your hands and face.
Reinforcement: Close doors and windows and fasten outdoor structures to prevent falling objects.
Disease prevention: People who are sensitive to temperature changes, such as the elderly, children, cardiovascular patients, asthma patients, etc., try not to go out.
Anti-skid: The road is slippery when the rain and snow hits, so be careful of slipping and falling when you go out.
Anti-gas poisoning: Families that use coal stoves for heating should beware of gas poisoning.
In short, this National Day holiday,
are not idle due to high temperature, cold wave and heavy rain.
The temperature in the central and eastern parts of the country is severe!
friends remember to add clothes in time~
Beware of physical discomfort caused by alternating hot and cold,
travel to take precautions against wind and rain!
