What season does aw stand for?
Autumn is one of the four seasons. In China, traditionally, "beginning of autumn" in the 24 solar terms is taken 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.
According to the average climate temperature of modern scholar Zhang Baokun, there are four seasons in a year. The index is that the average temperature is lower than 10℃ in winter, higher than 22℃ in summer, and 10~22℃ in spring and autumn respectively.
At present, the division of the four seasons in China is often based on the change of temperature, and the division of "climate average temperature" by modern scholar Zhang Baokun 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℃. 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". Entering autumn means that the hot weather has passed and it is beginning to cool down.
