High temperature weather warning

"I'm so hot." From continental Europe to London, England, Ms. Chen, who is taking her children on vacation, told the reporter of China Business News that she didn't expect Britain to be so hot.

The APP she showed to the First Financial Reporter showed that 18 local time was 3 pm, the temperature in London was 36 degrees, the highest temperature was 37 degrees, and the lowest temperature was 18 degrees. The European Meteorological Agency-European Meteorological Network (EUMETNET) issued a warning on the APP to beware of "obvious hazards caused by strong heat".

On the same day, the World Meteorological Organization (WMO) issued a statement predicting for the first time that the temperature in Britain would reach 40 degrees Celsius. The British Meteorological Office issued the first red warning of "extreme high temperature" in the history of the host country. In Portugal and Spain, the temperature has reached 46 degrees Celsius.

WMO also said that it is estimated that extreme high temperature will harm most parts of England earlier this week, and the temperature in some areas is likely to be above 35 degrees Celsius or even 40 degrees Celsius. In central, northern, eastern and southeastern England, the "Red Extreme High Temperature China Extreme Weather Warning" will last from Monday to Tuesday (July 18 to 19).

PaulGundersen, a top meteorologist from the British Met Office, warned, "It may be unusually warm at night, especially in urban areas. This is likely to cause extensive damage to staff and infrastructure construction. Therefore, the most important thing is that everyone will make plans for the summer heat and consider adjusting their daily life. This high temperature will adversely affect physical and mental health. "

Why did the record-breaking high temperature happen? According to WMO data, this is also the first time that Britain has predicted that the temperature will reach 40 degrees Celsius. On July 25th, 2009, the highest temperature in Cambridge Botanical Garden was 38.7 degrees Celsius.

According to WMO, some physical models at this stage show that the probability that the highest temperature in remote areas of Britain will gradually exceed 40 degrees Celsius next week has already exceeded 50%.

NikosChristidis, a weather attribution expert from the British Met Office, said: "In a recent scientific study, it was found that the probability of extreme high temperature in Britain has been increasing and will increase again in 2 1 century."

He showed that climate problems have affected the probability of extreme environmental temperatures in Britain. In the present climate, the probability that Britain lives at 40 degrees Celsius is about 10 times that of the present climate.

He also thinks that the probability that the temperature in any part of Britain will exceed 40 degrees Celsius in a year is still rising rapidly. "Even according to the current commitment of energy conservation and emission reduction services, this extreme situation is likely to happen once every 100 years."

WMO thinks that because of the change of global climate change pattern, extreme high temperature is indeed accompanied by natural climate problems. However, in recent decades, the improvement of working frequency, duration and compressive strength of this kind of thing is obviously related to the observed global warming and can be attributed to human activities.

WMO said that although the ambient temperature rise of 1 degree Celsius seems insignificant, the extreme high temperature caused by it has long been obvious in the observed climate records, which has universal and important harm.

The advice of the British Meteorological Office in the face of extreme heat includes, "Pay attention to these people who may not be able to stay cool and humid. The elderly, people with basic diseases and people living alone are particularly dangerous. "

"Keep the room cool: draw the curtain cloth of the house in Chaoyang District to keep the indoor space cool, and remember that it is probably cooler outdoors than indoors. If you go outdoors, please consider using cool indoor space. " The Met Office said it was necessary to "drink plenty of water to prevent excessive drinking. At the same time, it is forbidden to leave everyone in a closed parking car, especially babies, children or small animals. "

In addition, try to reduce sunlight 165438+ 0 am to 3 pm, when ultraviolet rays are best. If you need to go out in high temperature, please walk in the shade, apply sunscreen and wear a wide-brimmed hat, and prevent energy consumption at the hottest time of the day.

Extreme heat has flooded Portugal, Spain and France. In Portugal, the temperature has reached 46 degrees Celsius. Because hot weather increases the risk of fire, most parts of Portugal have issued a red warning.

In recent weeks, fires have swept through France and other European countries, including Portugal and Spain. By the week of 15, 7300 mu of land resources were on fire in Gironde province in southwest France.

According to the weather warning in France in the last week, 15 is listed as a "red" warning area and 5 1 is listed as an "orange" warning area in 96 provinces of France. The extreme high temperature in the midwest of France is expected to reach the highest value on 19, and the temperature will soar to about 40℃, and there is also an abnormal high temperature of 45.7 degrees Celsius in Spain.

According to WMO, a recent model science study published in Nature Geoscience concluded that the expansion of the Atlantic azores high system led to the worst drought in Iberian Peninsula in recent 1000 years.

At this stage, the high pressure area in the British air will slowly move eastward, passing through central and southern Europe. Please reach the northern Balkan Peninsula in the middle of next week. This will lead to high temperatures in most parts of western and central Europe.

LorenzoLabrador, a scientific and reasonable senior official of the World Meteorological Organization's global atmospheric monitoring project, shows that high temperature is not the only adverse effect of extreme high temperature. "Stable and stagnant air is like an outer cover, which can capture air pollutants containing fine particles and increase their concentration near the ground. This has caused a decline in the air index and adverse health hazards, especially for vulnerable groups. "

"Similarly, sufficient sunshine, some high-concentration air pollutants and stable air are also conducive to the production of reactive oxygen species around the ground, which has adverse effects on people and green plants." He said.
