There are heavy rains and high temperatures in many places in the south. Why is the south so badly hit this year?

According to the statistics of the National Disaster Reduction Center of the Ministry of Civil Affairs, since June 2, continuous heavy rainfall in southern China has caused floods, hail and geological disasters, resulting in the disaster of 200 counties (cities, districts) 1.76 million people in 8 provinces (autonomous regions) such as Jiangxi, Hunan and Guangxi, 9 people were killed, 5 people were missing, and1.20 million people were resettled urgently. More than 900 houses collapsed, and 1.3 million houses were damaged to varying degrees; The affected area of crops 1 13.5 thousand hectares; The direct economic loss was 2.88 billion yuan.

The Central Meteorological Observatory predicts that in the next three days, South China, Jiangnan and Guizhou will still be maintained? Rainstorm mode? . Sun Jun, chief forecaster of the Central Meteorological Observatory, said that the heavy rainfall in the south lasted for a long time this year. Compared with the same period of previous years, the rainfall in Guangxi, Guangdong, Hunan, Jiangxi, Zhejiang and Fujian is more than 1 ~ 2 times, and that in northern Guangxi is 3~4 times.

In addition, Meiyu in Jiangnan officially started on June 1 day, 7 days earlier than normal. After entering Mei, the intensity of precipitation in the south of the Yangtze River increased, and strong convective weather was active. Heavy precipitation may cause secondary disasters.

In the south? Flooded Jinshan? At present, the northern region has experienced a? Roast? Testing.

On June 3, the Central Meteorological Observatory issued the first high temperature warning this year. The highest temperatures in many places in North China reach 38 ~ 40℃, and those in Handan and Xingtai in Hebei reach 4 1.8℃, among which the high temperature at 19 observation station reaches or exceeds the extreme value in early June. Jinan and Beijing also experienced the first high temperature day this year. Due to the special geographical environment, high temperature weather also occurs in most parts of Xinjiang, and Aiding Lake in Gaochang District of Turpan City is as high as 45.8℃. Within a week, the Central Meteorological Observatory issued a three-day high temperature warning.

Many netizens exclaimed: It was so hot just after entering June. What can I do in July and August?

Although June and July are indeed the months with the highest number of high temperature days in some parts of northern China in previous years, there are also some high temperature days this year? Unusual? .

According to the data of the routine press conference of China Meteorological Bureau in June, the high temperature weather process in China appeared early, with a wide range and great intensity this year. On May 1-9, the earliest high temperature process occurred in the central and eastern regions since June 196 1, 49 days earlier than the normal value (June 19). In addition, the temperature is also higher than normal. In May, the national average temperature was higher than normal 1℃, the fourth highest in the same period since 196 1, and the highest temperature of 578 stations the next day exceeded the historical extreme value of the month.

After consultation with relevant units, the National Climate Center predicts that the temperature will be high in most parts of the country from June to August, and there may be staged high-temperature heat waves in western Huanghuai, Jianghuai, Jianghan, eastern Jiangnan and northeastern southwest China.

Uneven drought and flood? Why?

Wang Yongguang, chief of the National Climate Center, said that in general, June is also a time when precipitation in the south is relatively concentrated, but this time the rainfall intensity is relatively strong, such as the record-breaking local rainfall intensity, which is relatively rare.

Zhou Bing, director of the Climate Service Office of the National Climate Center, said that the high temperature in northern China in May and June was a weather process controlled by the continental high-pressure ridge. Under the control of the continental high, the downward current prevails, and solar radiation easily reaches the ground, so it is easy to appear this month? Barbecue day? . The promotion and intensity of high temperature weather also reflect from another side that extreme weather caused by global warming is increasing.

Zhou Bing also said that if the global climate continues to warm in the future, such extreme weather events will continue to increase.

China Meteorological Bureau held a press conference, saying that the climate situation in China this summer was generally on the high side, and extreme weather and climate events and precipitation were generally on the high side. More north and south, less middle? The spatial distribution of flood is heavier than drought, and there may be large floods in the middle and lower reaches of the Yangtze River, the middle and upper reaches of the Yellow River, the Haihe River Basin and the Songhua River Basin.

Global capital? Nowhere to run?

Not only in China, but also in the world, extreme weather is increasing. In May, the temperature of meteorological observation stations in 109 countries has reached or exceeded the extreme value in early May, and the locust plague that ravaged many countries this year is also related to the increase of abnormal weather.

The World Meteorological Organization (WMO) warned at the end of May that the northern hemisphere is entering summer, and it is expected that the record of high temperature will be broken again this summer, which may increase the illness of pneumonia patients, increase the infection rate and increase the burden on the medical system.

Studies show that by 2 100, most areas of India, Bangladesh and Pakistan will be close to the critical point of human survival limit, and the combination of high temperature and high humidity will also become a common phenomenon. Some researchers even predict that in another 50 years, the earth will have almost uninhabitable hot weather. ?

Combined with the increasingly frequent extreme weather in recent days, the above prediction does not seem to be alarmist.

The time for human beings to pay the price for their actions is getting closer and closer. If there is no substantive action, there will be more and more extreme climate on the earth, which will eventually endanger mankind.
