Autumn:

It is one of the four seasons: spring, summer, autumn and winter. China traditionally takes beginning of autumn in 24 solar terms as the starting point of autumn. Entering autumn means that rainfall and humidity tend to decrease or decrease, and everything in nature begins to mature from lush. At present, the four seasons are usually divided according to the average temperature of modern scholar Zhang Baokun.

Its index is that the average temperature is below 10℃ in winter, above 22℃ in summer and between 10 ~ 22℃ in spring or autumn. Autumn is a season of alternating hot and cold. Early autumn is still in the heat, but it hasn't come out yet. This is the hottest, wettest and sultry period of the year. After late autumn, it is sunny during the day, cool and dry at night, with large temperature difference between morning and evening, less rain and insufficient water. Therefore, autumn dryness has become the main feature of late autumn.

Overall characteristics:

Traditionally, beginning of autumn in 24 solar terms is the starting point of autumn in China. Autumn is composed of the characteristics of grain and fire, which means the maturity of grain. After entering autumn, in nature, everything begins to mature from lush. Its climate began to change from rainy and humid in summer to dry and rainy in autumn.

The division of four seasons in China is often based on the change of temperature, using the "average temperature" of modern scholar Zhang Baokun. According to the weather average temperature method, there are two main criteria to judge autumn. First, the average daily temperature for five consecutive days is between 10℃ and 22℃, which can be regarded as autumn and become a "short mark"; Second, the moving average temperature of five consecutive groups is lower than 22℃.

A set of moving average temperatures refers to the average temperature of the day plus the average temperature of the previous four days divided by 5 to get the moving average temperature of five days, which is a "sliding scale". Autumn divided by temperature means cool weather.
