Climatic and Phenological Characteristics of Mid-Autumn Festival

In autumn, the most obvious change of natural landscape is in trees. Urban society began to clean up a lot of fallen leaves, and many tourists flocked to the mountains to see the maple red.

Autumn is a transitional season from summer to winter. The lunar calendar is from beginning of autumn to beginning of winter from July to September, the solar calendar is from September to165438+1October, and astronomy is from autumnal equinox to winter solstice.

The phenological criteria studied by meteorologists are: after the summer heat, the average temperature for five days is below 22 degrees, which is regarded as autumn and ends below 10 degrees.

As can be seen from the date distribution map of beginning of autumn in China, Northeast China is the earliest place in eastern China. In autumn, the cold air from the north invades continuously, but its power is not very strong. In northern China, crisp autumn weather often forms, and in western China, continuous autumn rain often appears. The main meteorological disasters in autumn are: autumn rain in the west, cold dew wind in the south, frost and chilling injury at low temperature. Generally speaking, in autumn, the solar altitude angle decreases and the temperature decreases; The autumn wind is cool, the summer heat is gone, the fruits are covered with branches, and the fields are golden.

I hope I can have the bearing of the ancients. In the following autumn, I can feel the freshness and tranquility after the noisy summer, the short fragrance before the long winter, the heroism of "strong and firm autumn wind" and the helplessness of lamenting "terrible autumn wind and autumn rain". I will also be "felt" by autumn, but I will not be "sad" for autumn.

Moonlight is like running water, and running water is like boundless sky.

The hot and dry days in early autumn will be endless. I miss the moon that belongs to the Mid-Autumn Festival. Only in this way can people feel really cool and quiet. And the moon is often ignored by us in our daily life. Only when such a special day comes can people think of something about the moon.

The night is so quiet, with a hint of warmth in the silence, which makes the noise of autumn sound reach its climax in the treetops. The moonlight is blurred, swaying and unattached, creating a dense atmosphere, which reminds me of a sentence in Qin Guan's Walking on the Sand: When the fog clears, so does the moon. Memos with the word "fan" were captured.
