Chongqing will take stock of China's top 10 furnace cities at 40 ℃

The super typhoon nibert, which is about to land in Fujian coastal areas, will not affect the weather in Chongqing. But the extreme heat is coming. According to the latest forecast of Chongqing meteorological station, the local air temperature in Chongqing will reach 40 ℃ in the next three days. It is expected that next week, thunderstorms will be held all over the country, and the high temperature is expected to weaken.

It was a little hot yesterday. After the solar term, lotus root, Monopterus albus and mung bean sprouts should be eaten. When going out around noon, you should pay attention to heatstroke prevention. It is reported that the cause of this round of continuous fine and high temperature weather in Chongqing is affected by the westward extension of the vice high, and most areas may encounter the highest temperature since June this year.

Recently, a list of Chinese "stove" cities has been widely circulated on the Internet. It is understood that this is the first time that the meteorological department has released to the public authority the situation of hot summer cities in China by comprehensively analyzing the meteorological data of China's provincial capitals and municipalities in the past 31 years.

In the list released by the National Climate Center of China Meteorological Administration, the researchers, based on the comprehensive analysis of meteorological data in the past 31 years, concluded that the top 10 capital cities or municipalities directly under the central government in summer are Chongqing, Fuzhou, Hangzhou, Nanchang, Changsha, Wuhan, Xi'an, Nanjing, Hefei and Nanning.

Among them, Chongqing, Fuzhou, Hangzhou and Nanchang, which are in the forefront, have been named "the new four Furnaces" by many netizens.

In this regard, researcher Zhang cunjie of the climate and climate change assessment office of the National Climate Center believes that the term "stove" reflects the intuitive feelings of the public, but there has been no clear definition and standard.

It is understood that in the analysis and research of "hot city", the factors considered include the heat index (an index which mainly considers the comprehensive influence of temperature and relative humidity on human comfort), the number of high temperature days, the number of continuous high temperature days, the average maximum temperature and the minimum temperature in summer.

According to the distribution of average high temperature days in China in recent 31 years, there are two regions with the highest number of high temperature days. One is near Turpan Basin in the east of Xinjiang, the other is the South China area of South China including Hangzhou, Nanchang, Changsha, Fuzhou and other cities.

No matter which version of the "four Furnaces", Chongqing has always been "on the list.". In the 35 years since 1981, the number of high temperature days in summer in Chongqing ranked first among 10 cities, accounting for 28.5 days.

According to the results of the study, Wuhan, Nanjing and other traditional "stove" cities known to the public in the past are still on the list, but they have dropped out of the top four. Zhang cunjie said that this is related to the interdecadal changes of China's climate. "Meteorological studies have shown that climate change in North and South China has oscillation periods of about 20 to 30 years. In terms of the whole 30-year time scale, the temperature growth rate of cities in the Yangtze River Basin is not as fast as other cities, especially slower than many cities in northern China. "

Under the background of global warming, China's summer heat is generally increasing, and the list of "Furnaces" is getting longer and longer. Meteorological data show that from 1951 to 2010, the national average temperature increased by 1.38 degrees, increasing by 0.23 degrees every 10 years, which is basically consistent with the global warming situation. The range and frequency of extreme high temperature events and high temperature days increased.
