The weather has been sultry. When will it get better?

According to the forecast of the Central Meteorological Observatory, there will be continuous sunny, hot and high temperature weather in most parts of the south of the Yangtze River in the next 10 day. According to statistics, the death toll in Guangzhou will increase by 7% when the maximum temperature rises by 1℃, and it will increase to 16% for Shanghainese who are not as heat-resistant as Guangzhou people.

alarm

It will continue to be hot for the next ten days.

After several days of high temperature weather in the north and south, the Central Meteorological Observatory continued to issue high temperature warnings yesterday. It is estimated that on the 6th, it will be held in South China, South China, North China and Southwest China.

Persistent high temperature and hot weather.

The latest meteorological data show that in the next ten days, most of the south of the Yangtze River will continue to have sunny, hot and hot weather; There will also be five to eight days of high temperature and little rain in northern and eastern South China.

Zhejiang: It can reach 40℃ in some areas.

According to the high-temperature warning, it is expected that on the 6th, there will be high-temperature weather of 35℃ to 37℃ in most parts of the south of the Yangtze River, north-central South China, south-central North China, Chongqing, eastern Hubei, northeastern Guizhou, eastern southern Xinjiang and northern Xinjiang, among which the highest temperature in some areas of Zhejiang, central Jiangxi, central and western Fujian, Beijing and south-central Hebei can reach 38℃ to 39℃, and in some areas of Xinjiang it can reach 40℃.

Shanghai: The highest daily average temperature since 133.

Although the meteorological observatory predicted that the summer heat would ease on the 4th, the highest temperature in Shanghai still reached 38.3℃ on the 5th.

This is the first consecutive 1 1 high temperature day in Shanghai this summer, and it is also the fifth consecutive day that the temperature exceeds 38℃.

Yesterday, the Meteorological Observatory continued to issue a high-temperature red warning early in the morning, and upgraded the red warning to a black warning just after noon. This is the fifth black high temperature alarm in Shanghai this summer.

On July 3rd, the highest temperature in Shanghai reached 39℃, the highest temperature since July1. The average daily temperature has reached 35℃, the highest since 133!

Why is it so hot this year?

Global greenhouse gas emissions lead to global warming.

Zhou Lingxi, a researcher at the Atmospheric Composition Observation Service Center of China Meteorological Bureau, said that global warming caused by global greenhouse gas emissions has become an indisputable fact.

According to the annual report of the United Nations Intergovernmental Panel on Climate Change (IPCC)200 1, the global average temperature rose by about 0.6℃ in the last century, and the global temperature will rise by 1.6℃ to 5.5℃ by the end of this century, while the sea level will rise by 9 to 85 cm. "However, due to the different effects of emissions in different regions and the uncertain cooling effect caused by volcanic eruption or aerosol, the degree of warming in different regions is not the same, but it is warming in general." Zhou Lingxi said.

At present, it is also at a peak temperature in the history of the earth.

Every 6.5438+million years, the earth is a cycle of alternating cold and warm, and the alternating activities are mainly controlled by sunshine, and the sunshine amount of the earth is determined by its orbit and celestial orientation. "From the geological age, it is also at a temperature peak in the history of the earth, so it has superimposed some influences on the basis of global warming." Zhou Lingxi said.

What harm does high temperature do to people?

What harm does high temperature do to people? Different physical fitness and physical sensitivity have different effects on everyone.

Li Weijing, director of the National Climate Center, said that attention should be paid to heatstroke prevention and cooling, especially for the elderly, the weak, the sick and the disabled, such as cardiovascular diseases, hypertension and the spread of intestinal infections.

Gu Yue's sudden death may be related to high temperature.

Gu Yue, a famous special actor who successfully portrayed the great leader Chairman Mao for 84 times, died in Sanshui District People's Hospital of Foshan at the age of 68 at the night of 1 1: 09 because of sudden myocardial infarction during film and television activities in Lingui County, Guangdong Province.

According to Qilu, another special actor who participated in the activity with him, Gu Yue had no symptoms of heart disease before his death, and this sudden attack may be related to hot weather and physical fatigue.

Changes in temperature will affect the mortality rate.

According to statistics, the death toll in Guangzhou will increase by 7% every time the maximum temperature rises by 1℃, while for Shanghainese who are not as heat-resistant as Guangzhou people, the death toll will increase by 16%.

Usually, when the temperature does not exceed 33℃, the death rate in southeast China will not change obviously, but when the temperature is above 34℃, the death toll in Guangzhou will increase by 1 1%. The death toll of Shanghai residents even increased by 28%.

Modern people are far away from nature, and it is difficult to adapt to the sudden change of weather.

Professor Wolfgang Span, a German medical meteorologist, believes that the influence of weather is temperature, humidity and air pressure, which have a comprehensive impact on human tissues through human skin, respiratory organs, sensory organs and nervous system.

Human tissues and autonomic nervous system make human body have certain adaptability to weather changes, but because modern people are far away from natural life and unaccustomed to natural environment, it is difficult for many people to adapt to sudden changes in weather.

The longer you stay in an air-conditioned room, the worse your adaptability to temperature changes.

Lu Chen, a senior engineer of the Beijing Meteorological Society, said: "Now people's living standards have improved. If they stay in an air-conditioned greenhouse for a long time, their adaptability to temperature changes is relatively poor, which may easily lead to respiratory diseases in children and the elderly. Due to the destruction of the ozone layer, the increase of ultraviolet radiation reaching the ground will have an impact on the function of human skin, eyes and immune system. " "People are warm-blooded animals. The adjustment of temperature will increase the burden of cardiovascular and cerebrovascular diseases, and blood pressure and pulse will be affected, which is more dangerous for people with chronic diseases. " Lu Chen said.

The intense pace of life has changed the standard of human thermal comfort.

In addition, daily factors, such as increased calorie intake caused by diet structure, abnormal metabolism caused by tense pace of life, weakened heat dissipation through metabolites, reduced leisure time during the day, and increased indoor air conditioning space, have changed the standard of human thermal comfort. "Due to the trend of global warming, the atmospheric circulation situation has changed, and the frequency of extreme weather on the earth has also increased greatly-heavy rain, hurricanes, hail, high temperature and drought will become more and more frequent. In the past, the temperature above 40℃ in Beijing only appeared once every ten years, but now it appears almost every year, and more than once. Now the hot weather lasts longer. It was fine a day or two ago, but now it can't stand it for more than 10. "
