Autumn introduction:

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 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 lower than 10℃ in winter, higher than 22℃ in summer and higher than 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.

Phenology:

It is autumn in beginning of autumn so far, which means that precipitation and humidity are at the turning point of the year, and there is a tendency to decrease or decrease. In nature, everything begins to grow from lush to rich and mature. Autumn is the harvest season, and many plants mature in autumn. In autumn, in nature, the qi of yin and yang begins to change, the yang is fading, the yin is getting longer, and the climate changes from hot to cold.

Everything is born with cold and gradually falls, which is a season of alternating cold and hot. As the temperature gradually drops, the leaves of many deciduous perennial plants will gradually change color, wither and fall off, leaving only branches for winter. Panicum miliaceum will come to the end of his life, wither and die. Seasonal variation covers many aspects of climate characteristics.

It is not accurate to judge autumn simply by temperature. The most obvious change in autumn is that the leaves of vegetation change from lush green to yellow, and the leaves begin to fall and the crops begin to mature.
