What are the climatic characteristics of winter in winter

The climate characteristics of each place are different.

Climatic characteristics.

The beginning of winter, which means that winter begins here, is traditionally the beginning of winter with the 24 solar terms "beginning of winter". "Beginning of winter" means that wind, rain, humidity, light, temperature, etc., are at a turning point, gradually transitioning from autumn to winter. In winter, the direct sun point moves south to the Tropic of Capricorn and then turns back to the north.

At the beginning of winter, the height of the sun in the northern hemisphere becomes smaller, the daylight hours are shortened, and the amount of solar radiation in the northern hemisphere is getting less and less, but because the heat stored on the surface in the second half of the year still has a certain amount of energy, it is not very cold. During the Mengdong (beginning of the winter solstice and light snow), when it is sunny and windless, there is often a "small spring" weather with a beautiful wind and sunshine, warm and comfortable, and there is a saying of "October Xiaoyangchun" in the folk. In some parts of the south, the early winter (Mengdong) is generally not very cold during this period, but as time goes on, the cold air frequently moves south, and the temperature gradually drops.

In the northern region, it is very cold from the beginning of winter to spring, and the climate change of several solar terms in winter is not obvious, and snow is the main feature of winter in the north.

In some areas of southern China, during the beginning of the winter solstice light snow festival (equivalent to the tenth month of the lunar calendar), there is often a period of warm weather like spring, so that some fruit trees mistakenly think that spring is coming, and bloom for the second time, which is the so-called "warm in August and warm in September, and there is a small spring in October". In the winter season, the so-called "cold in Sanjiu", "Sanjiu days" is usually not very cold. Taking the winter solstice as the starting point, every "nine days" is counted as a "nine", and the first nine days are called"Nineteen", the second nine days called"Twenty-nine", and so on, the coldest time of the year is"Thirty-nine days"。

Since the winter solstice, it has begun to enter the "39 days", and the strong cold air moves southward frequently, the temperature plummets, and the weather is cold. So, the real cold in winter is after the winter solstice.

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 vicinity, the snow in the winter heavy snow season is often not as large as the light snow season, 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.

The climate in winter is characterized by cold and dry weather. In the north, in the cold winter, ice and snow, many animals in nature have returned to their nests and entered a "dormant" state of hibernation. Even in the south, because of the cold weather, short days and long nights, most people relatively reduce outdoor activities, go to bed early and get up early; Usually, add clothes and quilts to avoid the invasion of cold waves.

Therefore, due to the cold climate in winter, various diseases caused by wind and cold, such as nephritis, pyelonephritis, enuresis, urinary incontinence, edema, etc., are easy to ** or aggravate. Winter is mainly cold, if people can not add clothes and quilts in time, it can make people's resistance decrease, the heart and stomach, lungs and other organs dysfunction, and even cause tracheitis, stomach pain, coronary heart disease**, so that colds, joint pain, cough, rheumatoid arthritis, hypertension and other diseases occur or aggravate.

The temperature distribution in winter in China is characterized by a large temperature difference between north and south, and the temperature is lower the further north you go. The distribution of summer temperature in China is characterized by the general high temperature in the north and south.

1. Characteristics and reasons.

The characteristics of winter temperature distribution in China are as follows: the temperature is lower in the north and the higher in the south; There is a large temperature difference between the north and the south.

Reasons: 1. In winter, the sun shines directly on the southern hemisphere.

The noon sun in the north is smaller than in the south, and the day length is shorter than in the south.

There is less heat than in the south. 2. The winter monsoon moves southward, passing through the northern region first.

In the process of the southward movement of the winter monsoon, the force gradually weakens due to the obstruction of many mountains, so the temperature difference between the north and the south in winter is large.

2. General law.

The climate is complex and diverse, which is one of the main characteristics of China's climate. China's vast territory, spanning many temperature zones and dry and wet regions, coupled with China's complex topography and disparity in terrain, has increased the complex diversity of China's climate. There is a large difference in temperature between the north and the south in winter, the south is warm, and the further north you go, the lower the temperature.

In summer, high temperatures prevail in the north and south.

1. It's cold and snowy.

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 protect against the cold.

Snow only falls in winter, the air is fresh and comfortable, and when it snows, it is generally colder, and there is less of the sound of animals crying and cracking oranges. 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.

2. The days are short and the nights are long.

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.

3. 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 is an energy-saving process in which animal hibernation slows down and decreases breathing, body temperature, metabolism and heart rate. Hibernation is an instinct for animals, and they feel they should do it.

Latitude location.

There is a large difference in temperature between the north and south in winter in China, the south is warm, and the temperature is lower in the north, and the reasons for the temperature distribution in winter in China are as follows:

China's north and south spanning latitude is large, the direct sun point in the southern hemisphere in winter, the lower the sun altitude angle in the northern hemisphere, the less solar heat is subjected to, and the south of China is more affected by solar heat due to low latitude and large solar altitude angle.

The north of China is close to the birthplace of the winter monsoon, which is obviously affected by the winter monsoon and the cooling range is large, while the south of China is far away from the birthplace of the winter monsoon and is blocked by the tall mountains, the influence of the winter monsoon is not obvious, the cooling range is small, and the temperature is high.

Winter monsoons. The winter monsoon refers to the wind blown by the cold high pressure of the continent in the monsoon region in winter. In the winter of the Northern Hemisphere, the northwesterly winds, known as the winter monsoon, prevail due to the interaction of the Siberian high and the Aleutian low.

The winter monsoon phenomenon in East Asia is the most typical, with stronger winds than summer monsoons. China's winter monsoon comes from the inland land, the wind direction is northwesterly, and the climate is characterized by low temperature and little rain.

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.

An idiom that describes a winter scene

The snow is white, the ice and snow are dancing, the wind and snow are blowing, and the cold is pressing.

Thousands of miles of ice, the sky is cold, the ground is frozen, the cold flowers are late, the sky is closed, and the three friends of the cold year.

The cold is like this, the east is cold, the ice is cold, the sky is cold, the ground is frozen, the day is long, and the snow is flying.

The snow is worse, the winter and summer clouds send charcoal in the snow, and the winter wax in October is full of snow.
