The coldest months of winter are at their coldest months

Although from the winter solstice, the point of direct sunlight moves from the Tropic of Cancer towards the equator. But the weather in the Northern Hemisphere has not yet turned warmer. Because at this time, the cold air "accumulated" in the north continued to move south.

This extra bit of sunlight isn't enough to contend with. So the coldest time of the year is the Great Cold.

It's similar to how the hottest time of the day isn't noon. It was past 12 noon, although the sun was a little off. But the heat is still increasing.

So the hottest part of the day is usually around 2 p.m. The coldest time of the day is the time before and after the sun rises December 22 is just the lowest angle of the sun's altitude Not the coldest time Winter has three months, December, January, February, according to the normal law of nature, the midwinter season should be in January.

In addition, the Earth's movement to aphelion at the beginning of January receives the least amount of heat, so it should be the coldest month of January.

December 22 is the winter solstice, the sun shines directly on the Tropic of Capricorn, this day the northern hemisphere has the lowest solar altitude angle, this date is used to judge the direct sun point and the solar altitude angle, not to measure the temperature.

Because the warming of the earth's surface is not instantaneous, the radiation is at 12 o'clock at noon, and it takes a certain amount of time for the surface radiation to transfer the temperature to the atmosphere, so it is the hottest time of the day until around 2 o'clock in the afternoon.

12 o'clock is not the coldest reason, the same as above.

According to the solar terms, it should be around the winter solstice. And when the snow melts. It's from January to early February.

But it's not that the weather is cold that makes people feel cold, it's that there is no hope in the heart, no sustenance.

When a person has no motivation and courage to live, when he feels disheartened, it is extremely cold, that kind of bone-chilling cold.

The coldest time varies depending on the geographical location. The twelfth lunar month in the north is the coldest time.

It should be the wax moon, but now it is abnormal, and it is not necessarily.

The coldest months of the year are from December to FebruaryGenerally speaking, in the Northern Hemisphere, December is the coldest month of the year, which is the December of the Gregorian calendar. In the winter season, life is closed, and all things enter a state of recuperation and collection. Winter, that is, "the end, all things are collected", after the beginning of winter, all things begin to be closed.

The division of the four seasons reflects the characteristics of climate, phenology and other aspects. Now the four seasons are often divided according to the temperature change, using the modern scholar Zhang Baokun's "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.

There are a total of 81 days in winter, and the coldest case is Sanjiu, which starts on January 8 or 9 after the Xiaohan solar term, and those 9 days are the coldest conditions of the year. Normally, we will count nine as the beginning of the cold, and the end of the number nine also means the end of the cold.

Of course, it is because the climate is different in different places, and in some areas, the number of nine will be more than one nine. Depending on the region, the cold ends for a different period of time, usually from south to north, and the warm duration will be later. Of these, the southernmost part is not cold, and the northernmost part is warm after May.

On the winter solstice, the climate will be even colder next. This means that the coldest time of the year is just around the corner. Although the direct point of the sun slowly sways from the Tropic of Cancer to the north after the winter solstice, the kinetic energy of the solar radiation received by the earth is much lower than the kinetic energy lost, so the weather trend of the northern hemisphere map in the next month or two is to be colder.

Winter solstice

It is December 21-23 of the Gregorian calendar every year. During the winter solstice, the earth runs to the ecliptic longitude of 270 ° (the winter solstice point), the position of the sun directly hitting the ground reaches the southernmost point of the year, the sun almost directly hits the Tropic of Capricorn (also known as the winter solstice line), the sun is the most inclined to the northern hemisphere, the winter solstice is the shortest day of the year in the northern hemisphere, and the heat absorbed by the sun is also the least, which is the reason for the cold weather.

After the winter solstice, the direct point of the sun gradually moves northward, the days in the northern hemisphere begin to gradually become longer, and the height of the sun at noon gradually increases. From the climatic point of view, during the winter solstice, the average temperature in the northwest plateau is generally below 0, and the southern region is only about 6 to 8.

However, the influencing factors of temperature are more complex, in addition to natural factors, and human factors are also inseparable, such as exhaust emissions, coal burning, etc., will cause temperature fluctuations, and the coldest months in different regions are not the same.

November 7 this year is the 19th of the 24 solar terms - the beginning of winter.

Winter is one of the four seasons, the season between autumn and spring. Astronomically it is believed that it is from December to March, and it is customary in China to refer to the three-month period from the beginning of winter to the beginning of spring, and also refers to the lunar calendar "ten, eleventh (winter), and twelfth (wax) months", a total of three months.

The time is different in the northern and southern hemispheres. In terms of meteorological significance, in the temperate and cold zones of the Southern Hemisphere, winter falls in the month (May 21 and August 22 according to constellation standards), and in the temperate and cold zones of the Northern Hemisphere, winter falls in the month (November 21 and February 18 according to constellation standards).

According to the meaning of solar terms, winter begins at the beginning of winter and ends at the beginning of spring, while Westerners generally call the winter solstice to spring equinox winter. Climatically speaking, the average temperature is below 10 for 5 consecutive days to count as winter.

The small cold and the big cold are frozen into a ball. "A cold air after New Year's Day let Yangcheng know the colors of winter. Before and after the small cold, due to the sudden drop in temperature, the number of patients with colds in major hospitals increased sharply.

At present, many citizens exercise to enhance their physical fitness and resist the invasion of colds. However, experts in traditional Chinese medicine and Western medicine told reporters in unison that the morning in winter is not a good time to exercise, and improper morning exercise not only cannot strengthen the body, but may cause colds. The elderly are the main force of morning exercise, and they should beware of cardiovascular and cerebrovascular diseases during morning exercise in winter.

Summary. The coldest months of winter are the 10th and 10th months of the lunar calendar.

January, December" these three months.

What is the coldest month of winter.

The coldest months of winter are the 10th and 10th months of the lunar calendar.

January, December" these three months.

The coldest time is Sanjiu, which starts on January 8 or 9, and the next 9 days are the coldest time of the year.

December 21 or 22 is the winter solstice solar term, which means that in winter, the imitation stool begins to shiver and cold. January 5th is a small cold, and the coldest time comes. January 20 was a big cold and continued to be cold.

The coldest time is Sanjiu, which starts on January 8 or 9, and the next 9 days are the coldest time of the year. Ninety-nine days in the winter solstice solar terms to arrive at the time of the infiltration began to count, the day is called 19, after the nine days is called 29, a total of 9981 days, March 3 99 end. As the saying goes:

The heat is in the middle volt, and the cold is in Sanjiu.

December to February. In temperate regions of the Northern Hemisphere, 3 May is spring, August is summer, November is autumn, and December to February is winter. In the temperate zone of the Southern Hemisphere, winter is from June to August, summer is from December to February, autumn is from May, and spring is from November.

December to February. In temperate regions of the Northern Hemisphere, 3 May is spring, August is summer, November is autumn, and December to February is winter. In the temperate region of the southern hemisphere, June and August are winter, December to February is summer, May is autumn, and November is spring.

Winter is one of the four seasons, and the tradition is to start winter with the 24 solar terms, which means wind and rain, humidity, light, temperature, etc., at a turning point, beginning to transition from autumn to winter climate. Winter, that is, "the end, all things are collected", after the beginning of winter, all things begin to be closed. The division of the four seasons reflects the characteristics of climate, phenology and other aspects.

Now the division of the four seasons is often divided according to the temperature change, the air noise is the modern scholar Zhang Baokun's "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 be winter.

January to February are the coldest months of the year.

According to the statistical results of the multi-year average minimum temperature during the "Great Cold" and "Little Cold" solar terms, the average minimum temperature during the "Great Cold" solar term is lower than that of the Xiaohan solar term in most areas north of the Yellow River. In the area between the Yangtze River and the Yellow River, the "big cold" and "small cold" are as cold as ever;

In the area south of the Yangtze River, the "Xiaohan" solar term is colder than the "Dahan" solar term. However, this is based on the average situation, and whether the "big cold" is cold or the "small cold" cold is affected by many factors, and which one is colder needs to be analyzed in detail.

I think the coldest time of winter is usually around January, when it is really cold, and the cold air has basically arrived, and it even snows in some places.

It is supposed to be the coldest period from January to February every year.

According to the statistical results of the multi-year average minimum temperature during the "Great Cold" and "Little Cold" solar terms, the average minimum temperature during the "Great Cold" solar term is lower than that of the Xiaohan solar term in most areas north of the Yellow River. In the area between the Yangtze River and the Yellow River, the "big cold" and "small cold" are as cold as ever; In the area south of the Yangtze River, the "Xiaohan" solar term is colder than the "Dahan" solar term. However, this is based on the average situation, and whether the "big cold" is cold or the "small cold" cold is affected by many factors, and which one is colder needs to be analyzed in detail.

The coldest time varies depending on the geographical location. The twelfth lunar month in the north is the coldest time.

Singles' Day. Generally speaking, Singles' Day is probably the coldest day in winter for single people.

When is the coldest?

December 21 or 22 is the winter solstice solar term, which means that it has entered winter and is starting to be a little cold.

January 5th is a small cold, and the coldest time comes.

January 20 was a big cold and continued to be cold.

There are a total of 81 days in winter, and the coldest time is Sanjiu, which starts on January 8 or 9 after Xiaohan, and those 9 days are the coldest time of the year. Ninety-nine days in the winter solstice solar terms when the arrival of the beginning of the calculation, the day is called nine, nine days after the call two-nine, a total of nine nine 81 days, the solar calendar March 3 ninety-nine end.

As the saying goes: the heat is in the middle, and the cold is in the three-nine.

January is the coldest month around the Great Cold, and July is the hottest around the Great Summer.

What are the hottest and coldest days of the year? This problem is one place at a time on the planet.

So should the areas to the south or north be brought forward or postponed when agricultural production is carried out?

Autumn ripens to the south, and wheat to the north. Typical crops such as corn ripen first in the south and then in the north, while wheat is the opposite. For example, wheat, Binzhou and Jinan are 150 kilometers away from north to south, and the wheat ripening time is 10 to 15 days apart.

"The small cold is better than the big cold", that is to say, the small cold is colder than the big cold. Because "Ninety-Nine Song" thinks that it is a little cold, according to the saying "cold in Sanjiu". Xiaohan has a total of 15 days, of which 12 days are in the "three.

Nine, forty-nine", so it is inferred that the temperature is the lowest during the small cold period.

In China, it should be the three days around the Great Cold in the 24 solar terms, which should be the coldest days of the year according to the Chinese lunar calendar, but with global warming, and the influence of regional factors and other factors do not seem to be so accurate Related information: January 20 or 21 is the "Great Cold", and the original meaning of the Great Cold solar term is the coldest period of the year. However, except for South China, the coldest period in other places in China is in "March 9", that is, in mid-January.

The Great Cold Solar Term is mainly in the "Forty-Nine" and "Five-Nine", and the temperature has begun to rise slowly. Despite this, cold and dry weather is characteristic of the Great Cold. The three solar terms of "winter solstice", "small cold" and "big cold" are called "midwinter" by Chinese people.

In the middle of winter, there is an average of about once in 5 days or so cold air south, and cold waves, frosts, and heavy snowfall are the main disastrous weather in midwinter. There are 20 days with low temperatures below 0 and 3 snowy days in January. The Great Cold is the last solar term in the "24 solar terms", and the "Spring Festival" in many years is in the Great Cold solar term.

As long as people do not violate the agricultural season and arrange their production and life according to the characteristics of the weather, they will be able to pursue advantages and avoid disadvantages, improve the economic returns of industrial and agricultural production, and enhance the people's physical fitness, so that they can happily spend the Spring Festival.

In Beijing, January and December are the coldest months of winter.

December to January is the coldest time!

I think the coldest day of the year should be heavy snowfall. And I don't know why, as long as this day comes, it will be almost cloudy, and it will be drizzling and the wind will be biting.
