China has entered the "barbecue" mode. Why is it so hot this summer?

He Lifu, chief forecaster of the Central Meteorological Observatory, analyzed three major reasons for the rare high temperature in recent days.

He Lifu said that subtropical high is the main system that affects summer weather. This year, not only does the subtropical high control the southern region for a long time, but the intensity of the subtropical high itself is also very strong. In addition, there is no strong typhoon and subtropical high, which makes extreme high temperature weather appear in some places.

The reasons for this rare high temperature can be summarized into three points:

First of all, the rainy season in the middle and lower reaches of the Yangtze River is shorter than in previous years, and plum blossoms come out earlier. Since the beginning of July, the subtropical high has been continuously controlling the middle and lower reaches of the Yangtze River. Affected by downdraft, the weather is sunny, partly cloudy, with strong solar radiation and high atmospheric humidity.

Secondly, the intensity of subtropical high is obviously stronger than that of the same period in history. Last year, the middle and lower reaches of the Yangtze River were rainy in the first half of July, but this year, due to the early plum blossom, the number of high temperature days was obviously higher and the subtropical high was stronger, which led to the continuous rise of temperature.

Third, the atmospheric circulation is abnormal. So far, almost no typhoons have moved northward and inland. In previous years, because of the typhoon landing, the subtropical high will shrink and break under the influence of the typhoon, and the weather also presents a weather situation in which the typhoon cools down for a while, which is called intermittent high temperature.

This year's typhoon affected the south, mainly in the Taiwan Province Strait and the South China Sea, which caused the subtropical high to control the inland for a long time, and it is reasonable that the middle and lower reaches of the Yangtze River suffered from high temperature for a long time.

"barbecue" mode

Shanghai: "iron bacon"

On the afternoon of 29th 1 or so, a reporter from Shanghai TV Station did an experiment in People's Square: put a piece of pork belly on the marble floor, and the side stuck to the ground turned white after 30 seconds, and it was cooked in eight minutes after 10.

On July 30 12: 54, the reporter put a piece of raw bacon in a pot and put the pot on the road in Xujiahui business district, Shanghai. It takes about 80 minutes to fry raw bacon slices until they are half cooked, and the ground temperature has been higher than 60℃ during the whole process. On the same day, according to the Shanghai Central Meteorological Observatory, the highest temperature in Shanghai reached 39℃.

Jiangsu: "Grilled fish on the road"

On July 29th, in Zhenjiang, Jiangsu Province, a truck carrying fresh fish overturned at the Dantu Interchange connecting Liyang and expressway with Shanghai, Chengdu and expressway due to improper operation, and more than 30,000 kilograms of live fish were scattered all over the floor, temporarily causing one-way road interruption. Fortunately, the personnel were not seriously injured. Unfortunately, due to the high temperature in expressway, most fish are "baked" when they are picked up!

Hunan: Eggs hatch naturally

At noon on July 29th, in Loudi City, Hunan Province, Ms. Xie, who was cooking, cracked an egg. She found that the yolk was abnormal. When she saw it, it turned out to be the embryonic form of a chicken. Ms. Xie quickly smashed a few eggs and found that they were all in the same situation. According to Ms. Xie, "it may be that the recent high temperature weather has caused the room to become a natural incubator." .

"Eight Notices" in Hot Weather

First, when working outdoors, we should pay attention to taking effective protective measures to avoid exposing naked skin to the sun for a long time, and it is best to bring cold drinks;

Second, be careful not to run in the sun. Don't turn on the air conditioner immediately after returning to the room from the outside;

Third, try to avoid traveling from 10 morning to 4 pm, and replenish water before you are thirsty;

Fourth, pay attention to food hygiene;

Fifth, we should pay attention to maintaining adequate sleep and regular life and work;

Sixth, we should pay attention to the care of special people, especially the elderly and children. High temperature days are easy to induce cardiovascular and cerebrovascular diseases in the elderly, and children have bad symptoms.

Seventh, we should pay attention to prevent the onset of solar dermatitis after sun exposure;

Eight should pay attention to dizziness, nausea, dry mouth, unconsciousness, chest tightness, shortness of breath and other symptoms, should be suspected to be the early symptoms of heatstroke, immediately rest, drink some cold water to cool down, serious illness should immediately go to the hospital for treatment.
