When does March 9, 2022 start? When will it start on March 9, 2022? 202 1 65438+February 21. There are September 19 and September 29 before March 9, so when did March 9, 2022 start?

What time does March 9 start? 1March 9 starts from the first 19 day after winter on the solstice.

The calculation method is from the winter solstice to the winter non-union day (the first non-union day from winter to the future is called "Jiao Jiu", which means the beginning of cold), and every nine days are called "Jiu Jiu", the first nine days are called "Jiu Jiu", the last nine days are called "Er Jiu", the third nine days are called "San Jiu" and the fourth nine days are called "Jiu Si". At this time, it will be "nine peach blossoms" and "warm spring and deep days".

Jiujiu song:

From September 19 to September 29, fans never leave;

In 29 18, he took off his crown and put on his shirt;

3927, go out to sweat;

Four, nine, thirty-six, open-air rolling seats;

In 5945, autumn was like a tiger;

6954, too late to enjoy the cool;

7963, touching the sheets at the bedside;

In 8972, the coat was covered at midnight;

In 998 1 year, every family laid a coal foundation;

99 plus 19, the Mid-Autumn Festival is over.

What time does March 9 start? March 9 is the coldest time of the year.

There is no exact information about when the custom of counting nine originated. To be sure, at least in the Northern and Southern Dynasties, the custom of counting nine became popular. The Chronicle of Liang Dynasty and Jingchu wrote: "The number of winter solstice days, 998 1 day is the end of cold."

Is the coldest statement of "March 9" accurate? Data Emperor selected Beijing, Kaifeng, Nanjing and Xi 'an with a long history and complete meteorological data records, representing North China, Central China, East China and Northwest China respectively, based on the temperature data (195 1) of 60 years since meteorological records were recorded.

According to the data of 60 years from 195 1 to 20 10, the results of average temperature and extreme minimum temperature PK in these four cities during March 9 and April 9 are as follows:

Judging from the average temperature, except Xi 'an, the other three cities all support that "39" is colder than "49". What about the extreme minimum temperature?

Judging from the extreme minimum temperature, North China, Central China, East China and Northwest China, represented by these four cities, are also obviously in line with the statement that it is colder on March 9. The folk saying that "it's cold on March 9" seems to be well confirmed.

Why is March 9 the coldest?

We know that the earth absorbs the heat radiated by the sun during the day and radiates it at night. In summer, it absorbs more heat during the day and emits less heat at night, so it can retain some heat every day. In winter, less heat is absorbed during the day and more heat is released at night. Not only can you not keep it every day, but you should also use some heat left over from summer.

On the solstice of winter, the direct point of the sun is in the southern hemisphere, and the northern hemisphere absorbs less heat during the day, but fortunately there is still some stored heat. After the winter solstice, the stored heat is less and less day by day. By March 9, the heat stored in the northern hemisphere is the least in a year, so it is the coldest.

That is to say, when the solar heat absorbed by the ground is almost equal to the heat emitted by the ground, the temperature will reach the coldest degree.

"March 9 is cold", what about April 9?

In the Yellow River, Huaihe River and Yangtze River basins, "March 9" is still very applicable. Many partners in South China may have to raise objections, but those in the South are not as good as those in the South. Then let's take a look at the PK results of four provincial capital cities in South China.

Judging from the average temperature, April 9 in these four cities seems to correspond to a lower temperature. Although it is not cold, in South China, it is not true that it is cold on March 9. However, judging from the extreme minimum temperature, there was a cold low temperature in all four cities on March 9.

From this point of view, "March 9 cold" is not a universally applicable law. In the south of China, the cold of "March 9th" and "April 9th" have different experiences. Send a map of the coldest time distribution in the country, and friends from all over the country will take their seats, prepare the most cold-resistant equipment in time, and find the right time.

According to the statistics of perennial climate data in China, the coldest period of the year in most parts of northern China is 5438+ 10 in mid-June (5438+00 -20 in June), and in most parts of southern China it is 1 in late June. This year's "March 9th" is the middle of 10, from June 9th of 65438+ to June 7th of 65438+. For most parts of the north, "March 9" will be colder. However, for some areas in the south, the coldest in late June is 65438+ 10, which is April and September.

However, there are also some areas that are "different": western Sichuan and most parts of Yunnan are coldest in May 438+February at the end of June, probably during the winter solstice; The coldest time in Tibet and parts of Xinjiang occurred in early June of 5438+10.

It is worth noting that this map is based on the data of 198 1-20 10. With the climate change, from April 9 to May 9 (65438+1late October), many areas in the middle and lower reaches of the Yangtze River, such as Nanjing, Nanchang, Hangzhou and Hefei, became cold. Of course, from the comparison of the coldest areas in this picture, even now, "Sanjiu Leng" (65438+1mid-October) still has a "market".

The "March 9th Cold" is a climate generalization, which is still applicable to most parts of China, but it cannot be an absolute reference standard for a single year or two.

What time does March and September start? What's the weather like this winter?

1, cold air activity is frequent.

Around the early winter of this year, a cold wave affected many areas in China, and it snowed heavily in the north. Even the lowest temperature in Shenzhen, where the weather was warmer in the early winter, dropped to 5 degrees in the south. According to the latest forecast of national climate experts, cold air will appear more frequently this year, and there may be a cold wave in February and February 2022, which is three or nine days.

It was very cold at the same time last year.

In 20021year1month, North China such as Beijing and Hebei experienced several cold waves before and after, and the lowest temperature in history appeared. In the case of global warming, the same situation may occur, even lower than last year's temperature. Everyone should pay attention to prevention. Every year for three or nine days, it is either cold wave or rain and snow.
