The average annual temperature of my country's watches rises significantly

Beijing Evening News (Reporter Luo Qianwen) Yesterday (3rd), the China Meteorological Administration held a August press conference and officially released the "Chinese Climate Change Blue Book (2022)". "Blue Book" shows that the global warming trend is still continuing. In 2021, many climate change indicators such as the average temperature of China's surface, coastal sea plane, and many years of frozen soil activity layer have broken observation records.

"Blue Book" shows that the global warming trend is still continuing. In 2021, the global average temperature is 1.11 ° C higher than the level before industrialization (1850 to 1900), which is one of the seven warm years since the complete meteorological observation record. In the past 20 years (2002 to 2021), the global average temperature is 1.01 ° C higher than before industrialized. In 2021, the average temperature of the Asian land surface was 0.81 ° C higher than the perennial value (the Blue Book from 1981 to 2010), which was the 7th high value since 1901.

At the same time, China's heating rate is also higher than the global average at the same time, and is a sensitive area for global climate change. From 1951 to 2021, the average annual temperature of the Chinese surface was rising significantly, with a temperature increase rate of 0.26 ° C/10 years. In the past 20 years, it has been the warmest period in China since the beginning of the 20th century; in 2021, the average temperature in China is 0.97 ° C higher than the annual value, the highest value since 1901.

In terms of precipitation, "Blue Book" shows that from 1961 to 2021, China's average annual precipitation was increasing, with an average increase of 5.5 mm every 10 years; the annual precipitation continued to be more annual since 2012. In 2021, the average precipitation in China was 6.7%more than the annual value. Among them, the average precipitation in North China was the largest since 1961, and the average precipitation in South China was the least in nearly ten years.

From 1961 to 2021, China's extreme heavy precipitation incidents increased. Since the late 1990s, extreme high -temperature events have increased significantly, and the average intensity of Chinese typhoons has increased. In 2021, the average number of warm days in China has been the largest since 1961. The maximum temperature of 62 days such as Yuanjiang (44.1 ° C) and Sichuan (Fushun 41.5 ° C) exceeded the historical pole value. From 1961 to 2021, the average daily dust of the northern region decreased, and in recent years, it has reached the minimum value and has risen slightly.

In addition, global glaciers are in a state of ablation and retreat, and have accelerated melt since the mid -1980s. The Glacier No. 1 in Urumqi River, Tianshan, China, the Glacier Glacier in the Altai Mountains, No. 12, Luxou, Qilian Mountains, and the Xiadong Kima Glacier in the Yangtze River Yuanyuan District are accelerating the ablation trend. In 2021, the east of the glacier 1 and west of the Urumqi River, the end of the glacier 1 and the west branch of 6.5 meters and 8.5 meters, respectively.

According to the "Blue Book", China's overall vegetation coverage has increased steadily, showing a trend of turning.

This summer my country's regional high temperature intensity is the third strongest since 1961

Beijing Evening News (Reporter Luo Qianwen) The National Climate Center introduced yesterday that according to the latest monitoring and evaluation, the comprehensive intensity of the regional high -temperature heat wave event since June 13th has been ranked 3rd since 1961, second only to 2013 and 2013 and 2013 and 2013 2017.

Since the summer of this year (June 1st to August 2nd), the average number of high temperatures in the country is 9.2 days, which is 3.6 days more than the same period of the year. It is the most history since 1961. Southern North China, Huanghuai Middle and West, Southeast of the Northwest, Jianghan, Western Jianghuai, Sichuan Basin, most Jiangnan, central South China, and most of Xinjiang, western Inner Mongolia and other places are generally more than 20 days. Huanghuai, Jianghuai, Jianghan, Jianghan, eastern Jiangnan, Sichuan Basin, and western Xinjiang high temperatures are more than 10 days.

According to the monitoring and evaluation of the National Climate Center, since June 13, my country has emerged for the first regional high -temperature weather process this year. This process has the characteristics of long duration, wide range, strong strength, and strong extremes. As of August 2, the high -temperature incident has lasted for 51 days, covering an area of ​​more than 5 million square kilometers, affecting the population of more than 900 million people, and the maximum temperature of 131 national meteorological stations reached or broke through the historical extreme value. Hebei Lingshou (44.2 ° C), Tancheng (44.1 ° C), Zhengding (44.0 ° C) and Yunnan Yanjin (44.0 ° C) have the highest temperature of 44 ° C or above.
