65438+ 10 3, the first warning of high temperature and cold wave was issued!

Today, the Central Meteorological Observatory issued a blue warning of cold wave.

This is since 20 10 officially launched the early warning release mechanism.

Cold wave warning was first issued in the second half of the year.

At the same time, the hot weather in the south continues.

The Central Meteorological Observatory has issued a yellow warning of high temperature for three consecutive days.

This is also the first time that cold wave warning and high temperature warning are released at the same time.

According to statistics, at 15 this afternoon, high temperatures above 37℃ occurred in Jiangsu, Anhui, Henan, Hubei, Hunan, Jiangxi, Zhejiang, Fujian and other places, and nearly 200 national observation stations reached or exceeded the historical extreme temperature of 10.

Then, why do early warnings that seem contradictory and represent hot and cold poles appear at the same time? Hu Xiao, chief meteorologist of Weather Forecast Network, said that the subtropical high is very strong at present, which is the reason for the high temperature in the south. At the same time, the strong cold air in the north is coming, and the contrast between hot and cold will be great. Therefore, the Central Meteorological Observatory made an exception and issued a cold wave warning in advance to remind the public that the severe cooling during the National Day holiday may have adverse effects on traffic, production and life, and also caused rare cold waves and high temperatures. Summer is lingering, winter has knocked on the door, and passion is in autumn.

It will continue to be hot in the south tomorrow.

It is estimated that southern Henan, Anhui, southwestern Jiangsu,

Central and eastern Hubei, central and eastern Hunan, Jiangxi, Zhejiang,

Parts of central and western Fujian and northeastern Guangdong.

The highest temperature is 37 ~ 39℃

The local area in northern Jiangxi and northwestern Fujian can reach above 40℃
