What are the characteristics of the winter season? What are the characteristics of winter?

The main characteristics of winter are low temperature, fog, less insects, and relatively dry human beings. The whole winter includes six solar terms: the beginning of winter, light snow, heavy snow, winter solstice, small cold, and big cold. The day of the winter solstice is the day with the longest night and the shortest day in the northern half of the earth.

What is special about winter?

In winter, the weather is getting colder and colder, the northwest wind is blowing, and people put on thick cotton clothes, gloves, scarves, hats.

Geese and swallows flew south to spend the winter. The water of the creek froze, and the small fish played underneath. When it snowed, children played snowballs and had snowball fights in the snow.

The leaves of the willow trees have fallen off, leaving only bare branches, and some trunks are wrapped with straw to keep them warm. The grass also turned yellow. In winter, plum blossoms bloom.

In winter, bears, snakes, hedgehogs, frogs and many other animals hibernate. Cats and dogs have thick fur and are fat.

Stocking up on elite crops in winter. Folk are accustomed to take the "beginning of winter" as the beginning of winter, and the whole winter includes six solar terms: the beginning of winter, light snow, heavy snow, winter solstice, small cold, and big cold. The day of the winter solstice is the day with the longest night and the shortest day in the northern half of the earth.

Hello, feature one: cold.

Winter is the coldest time of the year. In the northern winter, the outside temperature can reach minus 10-20, and the cold winter can cause the river to freeze. People wear thick cotton clothes, gloves, scarves and hats to keep out the cold.

Feature 2: Snow.

Snow only falls in winter, when it is white, the air is fresh and comfortable, and when it snows, it is generally colder, and there is less of the sound of animal chirping. The snow in the south is like small particles, and the snow in the north is big and dry like tearing cotton. Ice cubes are hung in the low eaves of the house.

Feature 3: Short days and long nights.

Winter is characterized by short days and long nights compared to summer, and the day of the winter solstice is the longest night and the shortest day in the northern hemisphere. After the winter solstice, the days and nights gradually become the same.

Feature 4: Animal hibernation.

When the cold weather comes, the animals are unable to maintain the constant body temperature required for normal activities, so they have to find a place to hide and hibernate to survive the cold winter. Hibernation in animals is actually an energy-saving process, their bodily functions are slowed down, and their breathing, body temperature, metabolism, and heart rate all decrease. Hibernation is an instinct for animals, and they feel they should do it.

Cold, white, easy to feel lonely.

Features of winter:

1. Astronomy. In winter, the direct sun point moves south to the Tropic of Capricorn and then turns back to the north.

2. Phenology. Climatically speaking, the average temperature is below 10 for 5 consecutive days to count as winter. Winter in many areas means silence and desertion.

Organisms reduce their life activities when the cold hits, many plants lose their leaves, and animals choose to hibernate, some called hibernation. Migratory birds fly to warmer places for the winter.

3. Meteorology. In the Northern Hemisphere, winter is the coldest season, with temperatures that can drop below 0 even in temperate zones. During the winter months, many places experience snowfall, and the snow and ice in most parts of the north do not melt until spring.

4. Air humidity.

In summer, when the temperature is high, water is easy to evaporate into water vapor, so the more water vapor in the air, the more humid the air. In winter, when the temperature is low, there is less water vapor in the air, so it is dry. In geography, we call the degree of wetness and dryness of the air "humidity".

Of course, the reason why the air is dry in winter is not only the geographical reason that temperature affects the amount of water evaporated.

5. Animal hibernation.

In winter, many animals hibernate, and animal hibernation is actually an energy-saving process, their body functions slow down, and their breathing, body temperature, metabolism and heart rate will decrease. There is ice in winter, and skating on the river in winter. There will be no sweat in winter, and there will be proud plum blossoms in winter.

How beautiful winter is!
