Autumn Weather:

According to modern meteorology, the autumn in the north temperate zone is on August 23 (summer heat) and November 20 (light snow); Autumn in the southern temperate zone falls on February 19 (Northern Hemisphere rain) and May 21 (Northern Hemisphere Lesser Man).

At present, the division of the four seasons in China is often divided according to the temperature change, and the division of "waiting for average temperature" by modern scholar Zhang Baokun is adopted. According to the average temperature method, there are two main criteria for judging the beginning of autumn: first, the average daily temperature between 10 22 for five consecutive days can be regarded as autumn and become a "simple standard";

The second is: the sliding average temperature of 5 consecutive groups is lower than 22. A set of sliding average temperatures refers to the average temperature of the day plus the average temperature of the previous four days divided by 5 to obtain the 5-day sliding average temperature, which is the "sliding mark". Entering autumn means that the hot weather has passed and it is starting to cool down.

Autumn is characterized by yellowing of leavesIn autumn, most deciduous plants and trees begin to lose their leaves. The leaves are yellow and curly. They fall from the trees and are blown away by the wind.

Autumn is one of the four seasons of "Spring, Summer, Autumn and Winter". In China, the "beginning of autumn" of the 24 solar terms is traditionally used as the starting point of autumn. Autumn means that rainfall, humidity, etc. tend to drop or decrease, and everything in nature begins to grow from lush to mature.

Other features of autumn:

1. The leaves are yellow.

In autumn, most deciduous plants and trees begin to shed their leaves. The leaves are yellow and curly. They fall from the trees and flutter in the wind. This also means that after late autumn, winter is coming.

2. Wild geese fly south.

Every autumn, the cold climate of the north is no longer suitable for the geese to survive, and the geese fly to the warm south.

3. Fruitful.

The fruit on the trees is lush in the autumn harvest time.

4. Foggy.

When the relative humidity reaches 100%, the water vapor in the air will condense into tiny water droplets suspended in the air, reducing the visibility of the ground. This weather phenomenon is called fog. They mostly occur between February and April in the spring.

In autumn, there are many scenes, such as dancing leaves, uniform geese flying south, and beautiful autumn chrysanthemums in full bloom.

1. You may not perceive the beauty of the fallen leaves everywhere, but hundreds or even thousands of fallen leaves dance, especially when they fall to the ground, covering the entire tree-lined path, giving people a rather pleasant feeling.

2. Wild geese flying south. Every autumn, the wild geese fly south is quite a spectacle. Because of the changing climate, geese have to go to warmer places, so they start their long journey in autumn.

3. Chrysanthemums, blown by a gust of wind, are the fragrance of chrysanthemums, and the chrysanthemums use their own colors and fragrances to praise labor and praise the harvest of the earth. Rice fields, golden fields shining in the sun, looking from afar, look like a golden ocean.

Phenological phenomena in autumn

Autumn begins at the beginning of autumn, which means that precipitation and humidity are at a turning point in the year, tending to decline or decrease; In the natural world, everything begins to grow from luxuriant to fruitful and mature.

Autumn is the harvest season, and many plants mature in the fall. In the autumn season, in nature, the yin and yang energy begins to change, the yang energy gradually retreats, the yin energy gradually grows, the climate changes from hot to cool, and everything grows with the cold and gradually declines, which is the season of alternating heat and cool.

As the temperature gradually drops, the leaves of many deciduous perennials will gradually change color, wither, and fall, leaving only the branches to survive the winter. And an annual herbaceous plant.

They will come to the end of their lives, withering to death.

Seasonal transitions encompass many climatic characteristics, and it is inaccurate to judge autumn based on temperature alone. The most noticeable change in autumn is when the leaves of the plants change from lush green to yellow, and begin to fall and the crops begin to ripen.
