There is no winter information, urgently needed

Winter? About that?

You have to go into more detail.

Winter is the fourth season of the year in some areas, and as the weather turns colder (except in the equatorial regions), it means silence and desertion in many areas. When the cold hits, organisms will reduce their life activities, many plants will lose their leaves, and animals will hibernate, some called hibernation. Migratory birds fly to warmer places for the winter.

Signs of life in winter.

1. Squirrels scatter and bury the good food when they are about to enter winter, and then sleep in the tree hole in winter, and get up when they are hungry to dig out the buried food and eat. In addition, they can put eighteen pine nuts in their gills and stuff them before going to sleep.

2. Praying mantis can make very large egg masses, with 300 to 400 eggs in one piece, which together with secretions form oocysts. On the outside is a thick protective layer that adheres to the sunny trunk and is not afraid of ice, snow and cold winds.

Winter, one of the four seasons, is traditionally marked by the 24 solar terms "Lidong" as the beginning of winter. In the winter season, life is closed, and all things enter a state of recuperation and collection.

The division of the four seasons reflects the characteristics of climate, phenology and other aspects. The four seasons are often divided according to the temperature change, using the modern scholar Zhang Baokun's "waiting average temperature" method, according to the average temperature of the four seasons divided by the average temperature method, the average daily temperature for five consecutive days is equal to or lower than 10 degrees Celsius is considered to enter the winter.

Climate snow is an important symbol of winter in the north, in the middle and lower reaches of the Yellow River in northern China and its nearby areas, the snow in the winter heavy snow solar term is often not as large as the light snow solar term, the main reason is that the light snow solar term is in front, the temperature is high, the total amount of water vapor in the air is larger than the heavy snow solar term, and the greater the possibility of heavy snow.

In fact, the solar term with the heaviest snow and the most snow in the middle and lower reaches of the Yellow River and its vicinity is neither "light snow and heavy snow", nor "small cold and big cold" (because the temperature is lower and there is less water vapor in the atmosphere at that time), but the rainy season in spring.

Beginning of winter: The sun is located at 225° ecliptic longitude, and the conjunction occurs on November 7-8; Light Snow The sun is at 240° ecliptic longitude, at the intersection of November 22-23; Heavy snow The sun is located at 255° ecliptic longitude, and the conjunction dates December 6-8; On the winter solstice, the sun is located at 270° ecliptic longitude, and the conjunction occurs on December 21-23; Xiaohan The Sun is located at 285° ecliptic longitude and is intersecting on January 5-7; Great Chill The Sun is located at 300° of the ecliptic longitude, and the conjunction of January 20-21;

Winter Fun. Grandpa Winter hurriedly took over the autumn girl's class and came to us, it brought a cold wind, brought a cold scene, and made us feel that winter was coming!

When I woke up in the morning, it was foggy. A milky white mist covered the land, and everywhere it was white. Walking on the road, you can't see the figure clearly from dozens of steps; From the dense fog, the buildings and trees in front of you can only be faintly visible.

In the fog, I heard the sound of the car but couldn't see the human figure, only the headlights were like eyes, blinking and blinking.

The cold brought by winter spreads everywhere, even when it is sunny and windless, the weather is dry and cold. The bare trees stood pitifully on both sides of the riverside road, and the once vigorous grass finally could not support it and withered yellow. The little flowers on the grass also fell asleep.

The north wind blew, and the little trees struggled in the cold wind; The grass crept on the ground, as if afraid of the sudden cold wind.

In such cold weather, you can also see some strong people who are not afraid of the cold wind. In front of the flag stand on the campus, green figures flashed one after another. It was a row of slim cypress trees, which were as rich and green and vibrant as they were in the cold winter.

On the side of Jiangbin Road, many iron trees are planted. Its narrow, slender leaves shimmer green in the biting winter, adding greenery to the white winter and embellishing the cold winter.

In the early morning of winter, it is very lively. In Riverside Park, people exercising can be seen everywhere. In the vast mist, the figure kept shaking.

The young people were dressed like athletes, and they were all in good spirits. They were running and jumping, full of vigor and enthusiasm. The elderly also stepped out of the house, radiant stretching out their hands, kicking and jumping on the grass.

Don't look at them as old people, they are no worse than young people in sports, and they stubbornly fight against the biting cold. Look over there again, even.

Seven- and eight-year-olds also exercised with the adults, panting and steaming on their heads. Behold, what a vibrant winter!

I love winter because it sharpens one's will and makes one stronger. Winter you're finally here and pure!
