After the summer vacation: Isn’t it nice to blow the air conditioner in the house?
People can't help but feel
What cannot be taken away from Chengdu
There is only endless heat
How hot is it in Sichuan recently?
Why is it so hot this summer? How long will
continue to be popular?
Let’s take a look!

This year’s first high temperature red warning signal
On July 30, Jingyan County, Leshan City issued
The province’s first
high temperature red warning signal this year
Jingyan County Meteorological Bureau said
The maximum temperature may rise to Above 37℃
Chengdu continues to issue high temperature orange warning
The Chengdu Meteorological Observatory confirmed the No. 21 high temperature orange warning signal at 9:40 on July 31: It is expected that in the next 24 hours, Chengdu Eastern New District, Jinjiang District, Qingyang The maximum temperature in most towns (streets) in District , Wuhou District , Chenghua District , Jinniu District , High-tech South District, High-tech West District and Qingbaijiang District will rise to above 35°C, with high temperatures above 35°C. Mainly appears from 13:00 to 18:00.
Why is it so hot this summer?
It is understood that the sustained high temperature in the Sichuan Basin is caused by the influence of high pressure on the mainland.
The large-scale warm high-pressure system that appears over Sichuan in summer is called the Tibetan high-pressure system when its center is in the Tibetan Plateau; when its center moves eastward to the middle and lower reaches of the Yangtze River, it is called the Tibetan high-pressure system. High pressure for mainland China. When the Qinghai-Tibet High pressure controls Sichuan, there will be obvious sunny and hot weather, but it usually only lasts for two to three days. Under the control of mainland high pressure, sunny and hot weather will occur for a longer period of time.
This time, under the control of high pressure in the mainland, the high-pressure system on the one hand blocked the cold air from the north from moving southward, and on the other hand, it also blocked the water vapor from the South China Sea from being transported northward. There is no confrontation between warm and cold air currents over the Sichuan Basin, only downdrafts, resulting in continuous fine weather. At the same time, because there is less water vapor over the basin and less clouds in the sky, the sun's shortwave radiation reaches the ground directly, causing the ground to quickly heat up, thus starting the sunny, hot and dry mode. How long will
continue to be popular as ?
On July 29, the highest temperature in Sichuan Province occurred in Neijiang, which was 38.5℃; Emeishan, Leshan, Jianweisite temperatures (38℃, 37.9℃, 38.2℃) all exceeded the historical extremes of July temperatures. values (37.8℃, 37.8℃, 38.1℃).
According to the latest meteorological data analysis, the Sichuan Meteorological Observatory predicts that the current sunny, hot and drier weather will last until August 3 in most of the basin.
The coming weather may reach new heights in many places. As of the afternoon of July 30, 7 municipal meteorological departments in the province, including Chengdu, Deyang , Mianyang , Meishan , Leshan, Ya'an , and Suining, have issued high temperature blue warnings, while Neijiang, Guang'an Seven municipal meteorological departments, including , Yibin, Nanchong, Ziyang, Luzhou, Dazhou, sounded higher-level yellow high temperature warnings.
It is expected that in the next three days, temperatures of 37°C and above may occur in eastern Chengdu (Longquan Mountain).
The Dazhou Meteorological Observatory predicts that starting from July 31, in the next 3-5 days, the daily highest values will be in Xuanhan, Kaijiang, Quxian, Tongchuan, Dachuan, Dazhu and other places. The temperature generally reaches 37~39℃.
Affected by the weakening control of the mainland high pressure and the eastward movement of the plateau trough, beginning on August 4, relatively weak rainfall occurred in the capital of Sichuan Province, dominated by scattered thunderstorms or showers, and the weather changed from sunny and hot to humid and hot.
Experts from the Sichuan Meteorological Bureau remind:
△ High temperatures will lead to a decrease in human immunity and increase the possibility of heat stroke. Relevant units and personnel should do a good job in preventing heat stroke and cooling down. Try to avoid outdoor activities during high temperature periods in the afternoon.
△ Pay attention to fire prevention, ensure power safety and public health safety, strengthen fire source management, and do a good job in urban and rural fire prevention; prevent epidemics.
△ Facility agriculture should provide ventilation and cooling to prevent high temperature heat damage.
△ Pay special attention to heatstroke prevention and cooling for the elderly, weak, sick and young.
