The spring rain shakes the spring and clears the valley, and the summer is full of mountains and summers.

Autumn dew, autumn frost, little snow in winter and cold in winter.

The two festivals remain unchanged every month, with a maximum difference of one or two days.

The first half of the year is June 2 1 day, and the second half is August 23.

Beginning of spring:

February 4 -5 is the solar term that begins in spring.

Rain:

In February1August-20, winter went to spring, and the temperature began to rise, and the air humidity continued to increase, but the cold air activity was still very frequent.

Stunned:

March 5th (6th) means that the hibernating creatures in the winter dormant soil begin 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 at the equator, and day and night are almost the same length. 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 20, the rain increased, which was beneficial to grain growth.

Grain Rain

The long summer:

"Long Summer" on May 5th or 6th. Everything grows and prospers.

Xiaoman:

May 20th or 2 1 is called "Xiaoman". Summer crops such as wheat are full at this time, but not mature.

Many species:

Around June 6, when the sun moved to 75 degrees of the yellow meridian. Crops with awns, such as wheat, are mature enough to collect seeds.

Summer solstice:

Around June 22, the sun directly hit the Tropic of Cancer, and there was a phenomenon of "the sun arrived in the north, the day was long and the shadow was short", so it was called "summer solstice".

Slight heat in summer:

Around July 7th, summer came, which marked the hot season in most parts of China.

High temperature in summer:

Around July 23, it was around Zhongfu. 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.

Beginning of autumn:

On August 7th and 8th, the vegetation began to bear fruit, which was the harvest season.

Summer:

On August 23 or 24, "going out" means ending. By the end of the summer heat, the weather will be cool. As it is autumn harvest, precipitation is very precious.

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 22, the direct sunlight point returned to the equator, forming the same length as day and night.

Cold dew:

65438+1around October 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:

The first frost is around June 23, 10, and the first frost period in the Yellow River basin is generally in the late June of 10, which is consistent with the solar term of "first frost". Frost is very harmful to growing crops.

Beginning of winter:

Every year 1 1.7 or so.

Xiaoxue:

165438+1October 22nd is the "light snow" 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:

65438+around 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:

12 Around February 22nd, at this time, the sun almost points directly at the tropic of Capricorn, and the northern hemisphere forms a shadow from the south to the sun, short to the sun and long, 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.
