Autumn is one of the four seasons. Traditionally, China takes "beginning of autumn" in the 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 turn from lush to bleak. At present, the division of four seasons is often based on the average temperature of modern scholars. The index is that the period when the average temperature is below 10℃ is winter, the period when it is above 22℃ is summer, and the period when the average temperature is 10~22℃ is 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.

Autumn characteristics:

Traditionally, China takes "beginning of autumn" in 24 solar terms as the starting point of autumn. The word "autumn" consists of the word "grain" and the word "fire", indicating the maturity of the five grains. 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 four seasons in China are often divided according to the temperature change, and the "climate average temperature" of modern scholars is adopted. According to the weather average temperature method, there are two main criteria to judge autumn. First, the average daily temperature for five consecutive days 10℃-22℃ can be regarded as autumn and become a "short mark"; Second, the moving average temperature of five consecutive groups is lower than 22℃.
