What are the solar terms in winter? How many solar terms are there in winter?

The arrival of winter means that the weather will get cold. In the China lunar calendar, October, November and December are winter. So how many solar terms are there in winter? Let's take a look!

What are the solar terms in winter ① beginning of winter: 165438+ early October. Winter means the end, and it also means harvesting crops after harvest. There is a saying that radish and onion are "beginning of winter" in production, which means that these crops should be harvested and stored at this time. Astronomically speaking, from now on, winter will begin, and people will live in a relatively long cold season.

② Light snow:165438+1late October. At this time, the temperature continued to drop and it began to snow, but it was not very heavy. In the north of China, it's time for ponds and dams to freeze. When the cold wind blows, people feel that "the sky is crisp and the cold current is urgent" and "it is already hundreds of feet of ice on the cliff". At this time, the field is only for the collection and storage of Chinese cabbage. Farmland work basically stopped. Due to the continuous snowfall, there is a saying in the farmer's proverb that "there is a light snow all over the sky, and the next year will be fruitful".

③ Heavy snow: 12 at the beginning of the year. This solar term means that the temperature will continue to drop and heavy snow will come at any time, which will cause snow on the ground. Big means heavy snowfall. At this time, the earth froze and the pond froze. There is often a "heavy snow" that does not close the land, but it is said to be from the 3rd to the 5th. Once the clouds are overcast, people will think that in the severe winter, there will be magnificent pictures of "snow over the winter cloud Bai Yunfei, flowers bloom and flowers fall" and "there are no birds in the mountains, no footprints in the thousand paths, and the old people are fishing for snow in the cold river" at any time. Once it snows, the scenery in the north is covered with silver everywhere. When you see the snow-covered pine and cypress, you will think of Marshal Chen Yi's poem "The snow presses the pine and cypress, and the pine and cypress are tall and straight", and the integrity of being a man suddenly surges in your chest.

④ Winter solstice: 65438+late February. In the northern hemisphere, the days are the shortest (the so-called "winter solstice" is very short) and the nights are the longest. This is because at this time, the Arctic Circle in the northern hemisphere (that is, 66.5 north latitude) is in the extreme night period, just like the Antarctic is in the summer solstice (but only on the day of winter solstice). For the Arctic (that is, the area north of the Arctic Circle), the polar night can last 174 days. From the next day, the daytime time increased by 1 min for 20 seconds, and the nighttime time decreased accordingly. In life, people will feel that it gets dark early and dawn late, and it is difficult to know the night. "Winter" means "cold" and "to" means "to", which means it is colder when it is close. This solar term marks the beginning of cold weather. In the astronomical calendar, in order to show the beginning and degree of cold, in the printed calendar, "nine" is often used, that is, the so-called nine, two nine ... nine nine. Among them, "September" comes from "winter solstice", that is, the weather is cold in 8 1 day, and the third "September" (that is, the middle of January in the solar calendar) is the coldest.

⑤ Slight cold: 65438+1early October. "Cold" means cold. It shows that it has entered the cold season of the year, but it has not reached the coldest degree.

⑥ Great cold: 65438+1late October. Refers to the lowest temperature and coldest weather. This is the coldest season of the year. The weather is really chilly at this time, dripping into ice. When it snows, there is ice and snow everywhere. This is the reason why "Sanjiu" is usually cold. People who are used to working in busy farming season often transport soil mixed fertilizer to the fields at this time. This fertilizer is called "wax fertilizer" to keep wheat warm and safe for winter. In life, people will make various preparations for the upcoming Spring Festival and buy "new year's goods". Because the whole space of life is surrounded by cold, it makes people feel like they are in a natural "freezer", so food will not go bad if it is left casually for a long time.

What's the winter weather like in 20 17 in the northern hemisphere? In winter, the direct point of the sun is located in the southern hemisphere, and the solar altitude angle is small in the northern hemisphere. The atmospheric path of the same amount of solar radiation is relatively long, and more solar radiation is weakened by the atmosphere, so less solar radiation reaches the ground. At the same time, because the solar altitude angle is small, the same amount of solar radiation spreads over a large area, and the solar radiation per unit area on the ground is less. The temperature is relatively low.

How to keep fit in winter first: dress. It is very cold in winter. At this time, many people put on thick clothes to keep warm. But you know, at this time, the head, hands and feet all need to keep warm, which can never be ignored. Experts tell us that there is a very important role between the warmth of the head and the thermal balance of the body. Therefore, in order to be healthy, we should pay special attention to some exposed parts in winter, such as wearing hats and gloves.

Second: Exercise Many people stop exercising because of the cold weather, which is actually unscientific. When the temperature is low in winter, it is best for the elderly and children to reduce the number of outdoor activities, but don't stop exercising. Instead, we should do some simple exercise indoors, such as jogging, which will not increase the pressure on the heart and lungs, but also exercise. In addition, the exercise time is also particular, and it is best from 3 pm to 4 pm.

Third: Winter maintenance is a very important job. The colder the weather is, the more you should protect your hands and feet and form a good habit of rubbing your hands. Rubbing hands can not only promote the blood circulation of hands, reduce the possibility of frostbite, but also prevent colds and have a good health care effect on our brains. So rubbing your hands in winter is good for your health.
