The characteristics of autumn: the temperature drops gradually, the autumn wind is cool, the summer heat disappears, the fruits are covered with branches, and the fields are golden.
Autumn is the harvest season, and many plants mature in autumn. In the subtropical region of the northern hemisphere, the temperature in autumn is obviously lower than that in summer. As the temperature 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.
As can be seen from the date distribution map of beginning of autumn in China, Northeast China is the earliest place in beginning of autumn in eastern China. In autumn, the cold air in the north is constantly invading, but its power is not very strong. Autumn weather often forms in northern China, and continuous autumn rain often appears in West China. The temperature will gradually drop in autumn, but it is generally slower than in winter. Due to the difference of dry and wet conditions, there will be cold and rainy weather conditions or dry and cool weather conditions in different regions. In the cold late autumn, due to the large temperature difference between day and night, the water vapor transpiration during the day will condense at night, either dew or frost.
