Will the beginning of autumn be "autumn"?

"The disturbing heat has not retreated, and the cool soaring dive has risen." Lilu autumn indicates that the footsteps of autumn are coming, but at this time, the temperature in most areas in my country is still higher.

The season in the sense of modern climate is divided by temperature. According to the meteorological industry standard "Climate Season Division", when the average temperature of the five consecutive days in a certain place is lower than 22 degrees Celsius, it is considered to be autumn. According to this standard, from the perspective of the 30 -year temperature distribution during the national autumn, except for the Daxinganling and Qinghai -Tibet Plateau, the average temperature in most areas of the country is higher than 22 degrees Celsius. There are more than 25 degrees Celsius in the ministry, region, southern Xinjiang, etc., so the autumn does not mean that autumn has arrived, and the summer heat in most regions is still heavy. It takes a period of time to truly enter the autumn.

The autumn time in all parts of my country is very different. The majority of Jianghuai, northern Jianghan, east of the southwestern region, southern Xinjiang and other places entering autumn in September; most of the south of the Yangtze River, central and northern South China and other places in October; Most of the Qinghai -Tibet Plateau and the northern part of Daxing'an Mountains have low temperatures in the summer and low temperatures, and there is no summer in the climate sense. Spring and autumn are connected, such as Lhasa, Xining, Kunming, etc.
