How to correctly interpret autumn temperatures and weather?

Autumn’s beautiful names in ancient times include: the seventh month of the lunar calendar is called First Autumn, Mengqiu, Early Autumn, Early Autumn, New Autumn, and Last Autumn; August is called Zhengqiu, Zhongqiu, Mid-Autumn, and Guiqiu; and September is called Autumn. Late autumn, late autumn, cool autumn and late autumn.

In our country, the "beginning of autumn" of the 24 solar terms is traditionally used as the starting point of autumn. Entering autumn means that rainfall, humidity, etc. tend to decrease or decrease. In nature, the yin and yang qi begin to change, the yang qi gradually recedes, the yin qi gradually grows, the climate changes from hot to cold, and everything grows with the cold, and gradually declines.

According to modern meteorology, autumn in the northern temperate zone ranges from August 23 (summer heat) to November 22 (light snow); autumn in the southern temperate zone ranges from February 19 (rain in the northern hemisphere) to May January 21 (Little Full in the Northern Hemisphere).

Autumn temperature:

The Beginning of Autumn does not mean that the hot summer is about to pass. The Beginning of Autumn is still in the hot summer period and has not yet begun. The summer heat will not come until the second solar term in autumn. During the early autumn, the weather is still It's hot.

The so-called "heat is in the three volts". According to the calculation method of "three volts", the period from the beginning of autumn to the end of summer is often still in the "three volts" period, so the weather in early autumn is still very hot, and the real coolness usually does not come until after the Bailu solar term. The dividing line between hot and cold is in autumn, not at the turn of summer and autumn. The climate in autumn is divided into two stages. The early autumn is "sultry", and the mid-autumn period tends to be "dry" and "cool".

The autumn standard of climatological average temperature adopted in meteorology is that after the heat, autumn has entered when the five-day average temperature stabilizes below 22℃, and autumn ends and winter begins when it is below 10℃.
