It's raining.

Fight with others. The meridian of the sun is 330 degrees. At this time, the spring breeze blows all over, the ice and snow melt, the air is moist, and the rain is increasing, so it is called rain. People often say: Spring blossoms, rain is busy to send fertilizer.

This solar term means that after beginning of spring, the weather will get warmer, the spring thunder will start to sound, and all kinds of hibernating animals that are dormant in the soil will wake up and start to move, so it is called a fright. During this period, the eggs laid by overwintering insects will also begin to hatch.

As the saying goes:

Scared, warm and harmonious, toad sings folk songs.

Surprised as a plow, the vernal equinox is full of gas. The earthquake does not reach thunder, and the rain is like a dragon.

(4) vernal equinox

Fight with others. The meridian of the sun is 0 degrees. The sun is above the equator at the vernal equinox. This is the 90-day vernal equinox of spring. On this day, the northern and southern hemispheres are equal in day and night, so it is called the vernal equinox. After this day, the direct position of the sun moves northward, and the days in the northern hemisphere are long and the nights are short. So the vernal equinox is the beginning of spring in the northern hemisphere.

Overwintering crops in most parts of China have entered the spring growth stage. Agricultural proverbs in various places include: spring equinox comes first, rice competes for money (Guangdong), spring equinox is rainy, summer equinox is on fire (Sichuan), spring equinox is rainy, everyone is busy, first plant melons and beans, transplant rice seedlings (Hubei), spring equinox grows vegetables, summer picks melons (Hunan), spring equinox grows sesame beans, and autumn equinox grows wheat and garlic (Anhui).

The bucket refers to the southeast. The meridian of the sun is 45 degrees. Now it's long summer, and since then, everything has flourished. Traditionally, long summer is regarded as one of the most important solar terms when the temperature rises significantly, the summer heat approaches, thunderstorms increase and crops enter the peak season.

(8), Shoman

Nailing. The meridian of the sun is 60 degrees. Since Xiaoman, summer crops such as barley and winter wheat have borne fruit and full seeds, but they are not yet mature, so they are called Xiaoman.

(9), awn seed

Beidou points to itself. The meridian of the sun is 75 degrees. At this time, it is most suitable for sowing grain crops with awns, such as late rice, millet and millet. If you plant awns and crops after this time, it will not be ripe. Meanwhile, awn refers to crops with awns, such as wheat and barley, and species refers to seeds. Awn seeds indicate the maturity of awned crops such as wheat.

Before and after ear planting, the rainfall in the middle and lower reaches of the Yangtze River in Central China increased and the temperature rose. In the rainy season, the air is very humid, the weather is extremely sultry, and all kinds of utensils and clothes are prone to mildew, so it is also called mildew rain in the middle and lower reaches of the Yangtze River in China.

(10), summer solstice

Beidou points to B, and the sun meridian is 90 degrees. When the sun is at the summer solstice at 90 degrees of the yellow meridian, it is almost directly above the tropic of cancer, and the sun is the highest in the northern hemisphere at noon. This day is the longest day and the shortest night in the northern hemisphere. From this day on, it entered the hot season, when everything in the world grew most vigorously.

Therefore, in ancient times, this day was called the northern solstice, which meant that the sun moved to the northernmost day. After the summer solstice, the sun gradually moves southward, and the days in the northern hemisphere become shorter and the nights become longer.

(1 1), Xiao Shu

Fight each other. The solar calendar is 105. It's already very hot, but it's not the hottest time yet, so it's called Xiaoshu. At this point, it is already around the beginning.

(12), great summer

Fighting refers to C. The meridian of the sun is 120. The summer heat is the hottest solar term in a year. Before and after the next day's duty, high temperature weather of 40℃ often appeared in many places in the Yangtze River Basin. Do a good job in heatstroke prevention and cooling. There is a lot of rain in this solar term, so we should pay attention to the flood control and waterlogging prevention in the proverb that mice are flooded in the summer heat.

Beidou points southwest. The solar line is 135. From this day on, autumn began, the autumn was crisp, the moon was bright and the wind was clear. Since then, the temperature has gradually decreased from the hottest time.

(16), autumnal equinox

Fighting refers to yourself. The solar line is 180. The autumnal equinox and the vernal equinox are the same. The sun shines almost directly on the equator, and day and night are almost equal. From this day on, the position of direct sunlight continued to move from the equator to the southern hemisphere, and the days became shorter and the nights became longer in the northern hemisphere. According to China's autumnal equinox theory, this day is exactly half of the ninety days in autumn, so it is called autumnal equinox. But in astronomy, it is stipulated that autumn in the northern hemisphere begins with the autumnal equinox.

(17), cold dew

Nailing. The solar line is 195. After the white dew, the weather turned cold and dew began to appear. When the dew is cold, there is much dew and the temperature is low. So some people say that cold is dew, white first and then cold, which means that the climate will gradually turn cold. Water vapor condenses into dew.

(18), first frost

Fight with your fingers. The longitude of the sun is 2 10. It's already cold, and there is frost, so it's called the first frost.

(19), beginning of winter

Fight refers to dry. The meridian of the sun is 225 degrees. Traditionally, our people think that this day is the beginning of winter. Winter, as the end, means that after a year of field work, crops will be harvested.

(20), Xiaoxue

Fight against yourself. The meridian of the sun is 240 degrees. The temperature dropped and it began to snow, but it was not the season of heavy snow, so it was called light snow. Before and after the light snow, it began to snow in the Yellow River basin (snowfall in the south is two solar terms later); In the north, it has entered the freezing season.

Astronomy stipulates that this day is the beginning of winter in the northern hemisphere. After the winter solstice, the direct sunlight gradually moved northward, and the days in the northern hemisphere gradually became longer. As the proverb goes, eating noodles on the solstice in winter will make the day longer.

(23) slight cold

Fingers crossed, the yellow meridian of the sun is 285. After the slight cold, it began to enter the cold season. Cold air is cold for a long time, and slight cold means that the weather is cold but not extreme.

(24), severe cold

Fighting refers to ugliness, and the sun is 300 yellow classics. Great cold refers to extremely cold weather. Around the Great Cold is the coldest season of the year. The great cold occurred just after March 9 and at the beginning of April 9. As the saying goes, walking on the ice in 3949.

After the severe cold, spring came and the weather became warm. At this point, the earth made a revolution around the sun and completed a cycle.
