As the saying goes, "cold is in Sanjiu, hot is in Sanjiu", which means that the coldest time of the year in China is in Sanjiu days, and the hottest time of the year is in Sanjiu days. With the arrival of the winter solstice, it has officially entered the number nine cold days. The number nine, also known as the winter ninety-nine, is a method of calculating the date of spring flowers and cold days, and also represents the long and cold after entering winter. As the cold air continues to move south, everyone is more concerned about the cold and weather conditions this winter, counting nine cold days from the winter solstice, a total of eighty-one days, every nine days for nineteen, three nine forty-nine is the coldest time in winter, so which day is the third nine this year?Why is it the coldest?Is it warm for the Chinese New Year this year?Let's find out!
The number nine, also known as winter ninety-nine, is a relatively primitive method for calculating the cold and warm among the people in China. Winter is cold and long, and the ancients invented the method of counting nine in order to overcome the cold of winter and pass the time of boredom in winter. We are most familiar with the number of nine songs, "1929 don't shoot, 3949 walk on the ice" is about the cold scene in winter.
Generally speaking, among the nine cold days, three.
The coldest time is September and April 9th, and this period is the coldest time of the year. When you spend nine cold days and count nine hundred and eighty-one days, it is full of vitality, deep spring and warm days, and spring ploughing is timely. But our country is vast, the corresponding climate varies greatly, some places are warm in spring, some places are still very cold, there is no spring breath, "full of vitality, deep spring and warm day" corresponds to only some parts of our country, not all parts of the country, so the number nine is suitable for the cold and warm changes before and after the winter solstice in our country. In some cold regions, the temperature in winter and spring is minus Celsius, and the change in temperature is not obvious around the winter solstice.
At the beginning of our country, we did not count nine from the winter solstice, but the "winter solstice" counted nine, that is, the first "non day" after the winter solstice is the time to enter nine. But this method is very troublesome, because the time of the first "non day" after the winter solstice every year is almost different, and it is very inconvenient to calculate.
This year's winter solstice falls on December 22, which is the start of the number nine. After the winter solstice, the sun slowly moves north, the day time in the northern hemisphere slowly becomes longer, the winter solstice reaches the peak of the yin energy, the object pole must be reversed, and the yang energy begins to slowly generate after the winter solstice, so there is a saying that "the winter solstice is a yang birth".
19: From the winter solstice on December 22, 2023 to December 30, 2023;
Twenty-nine: from December 31, 2023 to January 8, 2024;
39: From January 9, 2024 to January 17, 2024;
Forty-nine: from January 18, 2024 to January 26, 2024;
Five-nine: from January 27, 2024 to February 4, 2024;
Sixty-nine: Beginning on February 5, 2024 and ending on February 13, 2024;
Seventy-nine: Beginning on February 14, 2024 and ending on February 22, 2024;
*: From February 23, 2024 to March 2, 2024;
Ninety-nine: Starts on March 3, 2024 and ends on March 11, 2024.
The winter solstice is not only the beginning of the number nine, but also the day when the sun reaches the Tropic of Capricorn, when the nights are the longest and the days are shortest, and then the direct point of the sun gradually moves north, and the daylight hours in the Northern Hemisphere gradually increase.
During this time, due to the longer nights and shorter days, the ground begins to dissipate more heat at night and absorb less heat during the day, which eventually leads to the heat being beyond its means.
Three. During the 9th and 49th periods, the heat of the ground reaches the minimum, and the surface temperature is also at the lowest. At this time, although the solar radiation has begun to gradually increase, the increase rate of the surface temperature is relatively slow due to the large specific heat capacity of the ground material and the low surface temperature.
Therefore, the period of 3949 has become a period of frequent cold waves. A cold wave is a sudden southward movement of a cold air mass from a high latitude, causing widespread windy and snowy weather and drastic cooling. During the period of 3949, once the cold wave moves south, due to the low surface temperature, the temperature will plummet, making 3949 the coldest period.
The Spring Festival in 2024 is on February 10, and the time period of June 9 is: February 5, 2024 - February 13, 2024, so the Spring Festival in 2024 is the sixth day of June 9, at this time the weather has been significantly warmer, there is an old saying "Five nine six nine, see the willows along the river", at this time people can already enjoy the beautiful scenery of the weeping willows. And the beginning of the spring solar term in 2024 is on February 4, the Spring Festival has been after the beginning of spring, at this time the yang energy rises, everything is reborn, the main climate characteristics are wind and day warm, the temperature rises, from this point of view, the Spring Festival in 2024 is relatively warm, not too cold.
But even though it may be warmer during the Spring Festival, it is still necessary to guard against the possibility of "cold spring". Spring is generally in the alternating season of winter and spring, the weather often changes greatly, and the cold air is frequent, and it is easy to have cold weather in spring. If the beginning of spring is too early, even if spring has come, the weather will still be as cold as winter, but the cold of spring and the cold of winter are not the same at all.
The above is an introduction to the number nine cold days and the coldest in Sanjiu, which were used in the past to advance the weather conditions of the first winter, and they are all the experience of the ancestors. But now the climate has changed from before, and there are more accurate weather forecasts, but the weather forecast is sometimes not necessarily accurate, and can only play a leading role, so these proverbs of the ancestors can only be used as a reference, and they are not necessarily accurate. The weather is ever-changing, and there are many factors that affect it, so you can refer to it and be mentally prepared. Do you think it's going to be cold this year?
