How hot is this summer?A set of data will take you to understand

On the 17th, the latest data released by the National Climate Center of the China Meteorological Administration showed that the comprehensive intensity of my country's high -temperature heat wave incident has reached the strongest meteorological record in 1961.

According to the analysis given by the China Meteorological Administration, this high temperature process is characterized by long duration, wide range, strong strength, and extremely extreme.

This round of high temperature lasts 64 days is the longest in 1961

Since this summer (June 1st to August 15th), the average number of high temperatures in the country has reached 12 days, which is about 5 days than the same period of the year.

Among them, the high temperature days in North China, East China, Southwest and other regions are generally more than 20 days. Henan, Hubei, Anhui, Jiangsu, Chongqing and other high temperatures have exceeded 30 days.

As of August 15, the high temperature process has lasted 64 days, exceeding the longest 62 days in 2013, the longest time since 1961.

The maximum temperature of 262 meteorological stations breaks the historical pole value

At present, the national meteorological observation stations have monitored 1680 sites above 35 ° C, and 1426 sites above 37 ° C. Both are the second most in history, second only to 2017. (Platform: 2017 is 1762, respectively, 1443 stations)

In addition, a total of 914 national meteorological stations in the country have reached the extreme high temperature event standards. Hebei, Shaanxi, Sichuan, Hubei, Jiangsu, Zhejiang, Fujian, Guangdong, Qinghai and other places 262 national meteorological stations have the highest temperature or break through history. Extreme value, more than 187 stops in 2013 and 133 stations in 2017.

This round of high temperature with a coverage of 40 ° C is the largest in history

Data show that the coverage of the high temperature of 40 degrees Celsius in this round is the largest, reaching 1.365 million square kilometers, far exceeding 776,000 square kilometers in 2013 and 993,000 square kilometers in 2017. Many cities have set a high temperature record, such as 44.6 ° C in Zhushan, Hubei, 44.5 ° C in Chongqing North, 44.4 ° C, Wuxi 44.0 ° C, Hebei Lingshou 44.2 ° C, Tancheng 44.1 ° C, Zhengding 44.0 ° C, Yunnan Yanjin 44.0 ° C. The maximum temperature in these cities has reached 44 ° C and above.

What is the reasons for the high temperature of this round? Experts of the Chinese Meteorological Administration explained three reasons.

Gao Ge, Chief Meteorological Service of the China Meteorological Administration: First, the influence of the atmospheric circulation is abnormal. In this summer, the atmospheric Global system shows the control of consistent heating and high -voltage circulation systems, forming a large -scale overall global heating high -pressure band affected by the high -pressure system. The hot air will stay on the ground. hot. The second reason is that La Nina climatic incidents spanning three years have helped the atmospheric circulation abnormality. The third reason is the role of global warming and heating up. In fact, the instability of the global climate system has been increasing in recent years. Extreme weather and climate events have frequently occurred. The abnormal conditions of Guangbang, Force, and concurrency climate appear more durable and frequent. More areas have encountered more compound extreme events. Continuous high temperature weather has brought many adverse effects on human health and agricultural production.

There will still be continuous high temperature weather in the next ten days

According to the forecast of the Central Meteorological Observatory, in the next 10 days, there are still continuous high temperature weather in Sichuan Basin, Jianghan, Jianghuai, Jiangnan and other places, and the cumulative high temperature days can reach 7 to 10 days. Can exceed 40 degrees Celsius. After comprehensive research and judgment, the duration of the regional high -temperature heat wave event in my country will continue to be extended, and the comprehensive intensity will be further enhanced.
