A good paragraph describing the fallen leaves in autumn:
Picking up a few fallen leaves that fell in front of my feet like elves, I was surprised to find that the fallen leaves in autumn are also like this. Colorful: the rich green has not faded away, but has added mature golden color; it may be old, with only a brown face. Although it is not as colorful as the sunset, and although it is not as gentle and elegant as the willow tree, it is enough to move people's hearts. Green like jade, brown like night, gold like clouds... intertwined into a colorful picture on the ground.
Autumn is a season of maturity, but it is also accompanied by the autumn wind sweeping the fallen leaves, ruthlessly blowing the autumn leaves from the trunks and branches of life. The fallen leaves are like the dusk of life, in the wind of autumn. , in the baptism of endless years, slowly withering away her life, she devoted her life to nature, and she locked her love for life firmly on the trunk of life. Maturity is a kind of life. Perfection, with the advent of autumn, the fallen leaves slowly shake off the wings of life in the cool air. Her withering, her drifting, and the following of her soul all go with the dripping of natural wind and rain. Break away and merge into the new natural heart forever. Walking is to better stay in the natural scenery. Walking is for new life, new life renewal and dancing space.
I bent down to pick up the fallen leaf and looked at it, thinking about how it looked when I was young. It must be verdant and tender, and must have clear veins, but even if it has a shocking brilliance of life, it cannot deviate from the laws of nature. As the clouds roll in and the tide rises and falls, its soft leaves dry up unconsciously, and the orange patches on the leaves are the imprints left by the wind and rain.
In autumn, the most obvious changes in the natural landscape are on the trees. A large number of fallen leaves will begin to be cleared in the city, and many tourists will flock to the mountainous areas to watch the red leaves. Autumn is the third season of the year, the transitional season from summer to winter. The lunar calendar is from the beginning of autumn in July to the beginning of winter in September. The solar calendar is from September to November. The astronomical period is from the autumnal equinox to the winter solstice. The standard for meteorologists to study phenology is: after the heat, autumn is considered to have entered when the five-day average temperature stabilizes below 22 degrees, and autumn ends when it falls below 10 degrees.
There are six solar terms in autumn, namely: Beginning of Autumn, End of Heat, White Dew, Autumnal Equinox, Cold Dew, and Frost Descent.
The temperature will gradually drop in autumn, but generally more slowly than in winter. Due to the difference in dry and wet conditions, different regions will experience cold and rainy, or dry and cool weather conditions. In the colder late autumn, due to the large temperature difference between day and night, the water vapor that evaporates during the day will condense at night, either as dew or frost.
In autumn, the direct sun point gradually moves southward from the northern hemisphere. After the autumnal equinox, it crosses the equator and the sun shines directly on the southern hemisphere. From the northern hemisphere, the angle of the sun gradually becomes lower, and the difference between the length of day and night becomes smaller. During the autumnal equinox, day and night are of equal length. In autumn, the distance between the Earth and the sun gradually gets closer. Viewed from the ecliptic plane, the Sun is located against the background of Leo, Virgo, and Libra.
