Song of the 24 solar terms and the moon
Beginning of spring: February 4th-5th is the solar term that begins in spring.
Rain: February1August-20 Winter comes and spring comes, the temperature starts to rise, and the air humidity keeps increasing, but the cold air activity is still very frequent.
Sting: March 5th (6th) refers to the winter when hibernating organisms in hibernating soil start to move. It was cold and warm before and after the shock, and the temperature and wind changed greatly.
Vernal equinox: On March 20th (or 2 1) every year, the sun shines directly on the equator, and day and night are almost equal. Overwintering crops in vast areas of China will enter the spring growth stage.
Qingming: On April 5th (or 4th) every year, the temperature rises and the weather gets warmer. Grain Rain: Around April 20th, the rainfall increased, which was beneficial to grain growth.
Long summer: "Long summer" on May 5th or 6th. Everything grows and prospers.
Xiaoman: May 20th or 2 1 called Xiaoman. Summer crops such as wheat are full at this time, but not mature.
Ear seed: around June 6, when the sun moves to 75 degrees of the yellow meridian. Crops with awns, such as wheat, are mature enough to collect seeds.
Summer Solstice: Around June 22nd, the sun shone directly on the Tropic of Cancer, and "the sun arrived in the north, the days were long and the shadows were short", so it was called "summer Solstice".
Slight summer heat: Around July 7, it entered a hot summer, which marked that most parts of China entered a high temperature season.
Summer heat: About July 23, just before and after the mid-fall. This period is the hottest period in a year in China's vast areas, but there are also abnormal years, "summer is not hot" and there is more rain.
Beginning of autumn: On August 7th or 8th, the vegetation begins to bear fruit, which is the harvest season. Summer: August 23 or 24, "going out" means ending. When the summer heat draws to a close, the weather will get cool. As it is autumn harvest, precipitation is very precious.
The Millennium: Around September 8, the temperature dropped rapidly and the weather was cool because the direct point of the sun moved southward obviously. Water vapor close to the ground at night forms white dew on vegetation, hence the name "white dew".
Autumnal Equinox: Around September 22nd, the point of direct sunlight returns to the equator, forming equal length of day and night.
Cold dew: around 65438+1October 8. At this time, the direct point of the sun continues to move southward, the temperature in the northern hemisphere continues to drop, the weather is colder, and the dew has a strong chill, hence the name "cold dew wind".
First frost: around June 23rd of 10, which is called "first frost". The first frost period in the Yellow River basin is generally in late June, 10, which coincides with the "first frost" solar term. Frost is very harmful to growing crops.
Beginning of winter: Every year165438+1around October 7th.
Xiaoxue:165438+1October 22nd is the "Xiaoxue" solar term. The influence of cold air in the north is enhanced, the temperature drops rapidly, and snowflakes appear in precipitation. However, this is the first snow stage, with less snow and fewer times. Most of the Yellow River Basin snows after the "light snow" solar term.
Heavy snow: around 65438+February 7. At this time, the direct point of the sun is close to the tropic of Capricorn, and the days in the northern hemisphere are short and the nights are long.
Winter solstice: around 65438+February 22, the sun almost points directly to the Tropic of Capricorn, and to the south of the day, a long shadow is formed in the northern hemisphere, making it the shortest day in a year. After the winter solstice, the days in the northern hemisphere became longer and the temperature continued to drop, entering the "March 9" with the lowest annual temperature.
Slight cold: around 65438+10.5, the climate began to get cold.
Great cold: 65438+1around October 20th, the coldest time of the year.
