Beginning of spring: February 4th or 5th is the solar term in beginning of spring every year.

Rain: February 19 or 20 Every 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 5 or 6 every year means that hibernating creatures in hibernating soil start to move in winter. 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 day 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 4th or 5th every year, the temperature rises and the weather gets warmer.

Grain Rain: On April 20th or 2 1 every year, the rainfall increases, which is beneficial to grain growth.

Long summer: On May 5th or 6th every year, everything grows and prospers.

Xiaoman: On May 2 1 or 22 every year, summer crops such as wheat begin to be full, but they are not mature.

Ear seed: on June 5 or 6 every year, when the sun runs to 75 degrees of the yellow meridian. Crops with awns, such as wheat, are mature enough to collect seeds.

Summer solstice: On June 2 1 or 22 every year, the sun shines directly on the Tropic of Cancer, resulting in "the sun arrives in the north, and the days are long and the shadows are short", hence the name "summer solstice".

Slight summer heat: On July 7th or 8th every year, the summer heat enters, which indicates that most parts of China enter the high temperature season.

Summer heat: July 22nd or 23rd every year, just before and after the upper abdomen. This period is the hottest period in a year in China's vast areas, but there are also abnormal years, "there is no heat in summer" and there is more rain.

Hot summer: On August 23rd or 24th every year, "hot summer" means the end. By the end of the summer heat, the weather will be cool. As it is autumn harvest, precipitation is very precious.

Bailu: On September 7th or 8th every year, due to the obvious southward shift of the direct point of the sun, the temperature drops rapidly and the weather is cool. Water vapor close to the ground at night forms white dew on vegetation, hence the name "white dew".

Autumnal equinox: On the 23rd or 24th of September every year, the direct sunlight point returns to the equator, forming equal length of day and night.

Cold dew: June 8th or 9th every year 10. At this time, the direct point of the sun began to move south, the temperature in the northern hemisphere continued to drop, the weather was colder, and the dew was cold, hence the name "cold dew wind".

First Frost: On June 23rd or 24th of 5438+1October every year, the first frost period in the Yellow River Basin is generally in the late of 5438+1October, which coincides with the "first frost" solar term. Frost is very harmful to growing crops.

Beginning of winter: Every year165438+1October 7th or 8th, beginning of winter.

Light snow: On June 22nd or 23rd every year,165438+1October, the cold air force in the north is strengthened, the temperature drops rapidly, and snowfall occurs in precipitation. However, this is the first snow stage, and the amount of snow is small and the number of times is small. After the "light snow" solar term, most of the Yellow River Basin snowed.

Heavy snow: 65438+ February 7th or 8th every year. 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: February 22nd or 23rd every year, 10. At this time, the sun shines almost directly on the tropic of Capricorn, and the northern hemisphere forms the southern part of the solstice, with short days and long shadows, which is 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: Every year, on the 5th or 6th of October, 65438/kloc-0, the climate began to get cold.

Severe cold: 65438+ every year1October 20th or 2 1 day, which is the coldest time of the year.
