Cold! Cold! Cold! The first cold wave warning was issued in the second half of this year. Which areas will encounter cold waves?

Bian Xiao learned from China Meteorological Bureau today that cold air may affect the temperature in most parts of central and northern China, leading to strong winds and strong cooling. The Central Meteorological Observatory announced the cold wave blue warning on the morning of the 2nd, which was the first cold wave warning in the second half of the year.

"Several provinces and regions will experience a temperature explosion." Zhang Tao, chief forecaster of the Central Meteorological Observatory, said that before the arrival of strong cold air, large-scale continuous high temperature weather occurred in various parts of the southern region; When strong cold air comes, there is moderate to heavy rain from west to east in the eastern part of northwest China, North China, Huanghuai, Jianghuai, Jianghan and the northeast part of southwest China, accompanied by strong convection. After the strong cold air, most of the above areas cooled down strongly.

Affected by cold air, the temperature in most parts of central and northern China dropped by 8 ~ 12℃, and the temperature in central and northern Inner Mongolia, Northeast China, most of Shaanxi, southwestern Shanxi, Huanghuai, Jianghuai, northern Hunan, northwestern Jiangxi, southern Anhui, southern Jiangsu and northern Zhejiang dropped by 12 ~ 16℃, among which

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 and its north, and tornadoes at high altitudes and rivers and lakes can reach 7 ~ 8. There will be 7-8 winds and 9- 10 tornadoes in the northeast and east China seas.

Previously, high temperature weather occurred in many places in the southern region. By the 4th, the high temperature will continue in parts of Jiangnan, northern South China, Jianghan and Jiangzhun. Generally, the maximum daily temperature is 35℃ to 37℃, 38℃ to 39℃ in some areas and above 40℃ in some areas.

"The high temperature weather is mainly caused by the rare and prosperous subtropical high hazard in historical time." Zhang Tao introduced in detail that 1 day, the highest temperature in the middle and upper reaches of the Yangtze River has also got rid of the historical highest. From 2 to 4 days, before the cold air moves south, the category of continuous high temperature in the southern region will continue to expand to a certain extent, and the highest temperature will continue to rise to a certain extent, which is likely to set a new historical record again.

She told reporters that the "sudden drop" of low temperature first and then low temperature and temperature may be the most profound experience of people's holiday weather changes in the next few days. In addition, some areas in Sichuan, Shaanxi, Henan, Shandong and other places will have strong rainfall, some areas will have heavy rain, local areas will have short-term heavy precipitation, and local areas will have lightning and strong winds.

Zhang Tao reminded the masses to immediately pay attention to the weather forecast and early warning reminder, pay attention to adding clothes to keep warm, and make preparations in advance to deal with the windy and cool weather to prevent physical discomfort caused by cold and hot; Fasten doors and windows, baffles, sheds, temporary structures and other structures that are easily blown open by strong winds, and properly solve outdoor objects affected by strong winds; Pay attention to the latest news of the related news media about the gale cooling, so as to take further countermeasures.

In addition, the meteorological department suggested that in the next three days, natural disasters, landslides and other climate risks will occur in parts of northeastern Sichuan and southwestern Shaanxi due to continuous rainfall. Please prevent going to the mountains and some valleys to play; People who play in rivers, lakes and seas need to pay attention to the early warning and warning of nearby weather forecasts and take preventive measures or change their distribution as soon as possible.
